Severe Tire Blowout
 
Has anyone had an experience like this....We are driving along towing our x23b , when the left rear tire blows, tearing it to shreds. While the AAA guy is replacing with spare, we notice that all the other tires are worn down to the steel belt on the inside of the tire only..i had to crawl to
the nearest tire dealer , get four new tires but now what?

Question: what would cause this? Appears to have 'lost camber' according to the dexter manual....please help!

Bucko06 08-31-2016 06:51 PM

Have you weighed your unit? I am thinking that weight causes axle deflection which could give camber in a tire.

norty1 08-31-2016 07:00 PM

Is this a new rig. You may need the axle alignment checked and a trip to the scales.

RickAE 08-31-2016 07:08 PM

Some of the White Hawk TT had been built with the wrong axles. Mine had to be changed. Don't know if this is your problem, but read the thread shown below. There is information to contact Dexter in that thread if there is something wrong with the axles.https://www.jaycoowners.com/forums/f3...ted-15137.html

Jagiven 08-31-2016 07:16 PM

A little more info could be helpful. How old of a htt? Are they the original tires? Do you check the tires often, ie wear, tire pressure? How fast do you tow? Have you ever checked your weight to ensure your not overloaded?

As for wear, I had that issue with one tire, but it was due to how I have to back into my driveway.

Blowouts on trailers usually are not good.

Severe Tire Bliwout
 
thanks for the replies...we've had the trailer almost two years now and have put on probably 7,000 miles, then this happens ...the load was not excessive ...the only new thing i did was have about 6 gallons of fresh water in tank , seems like about 60 lb , again , not excessiive.

I was driving on a bumpy road when it happened but I've been on far worse with problems like this.

I have read posts that talk about poorly rated axles, but wouodnt that have happened much sooner than now.

Also what i dont understand how i seemed to lose camber, ie i guess the 'natural' bend was lost in BOTH axles at the same time??

bankr63 09-01-2016 12:56 PM

The first step for me would be a trip to a CAT scale to find out exactly what the load on your trailer is. There is a bit of natural camber in regular axles that flattens out as load is added. But if overloaded, they will over deflect and wear the inside of the tires. I am not sure if the Torflex setup does the same thing? Regardless, you may be surprised at how much all of your trailer cargo actually weighs out to when you have less than 800 lbs to play with (the 23B actually has a fair bit less CCC than our 19H, so I know how tight it can be).
I did bend the axle on our pup trailer after hitting a large road swale with a near full load. I wasn't overweight, but that big a bounce certainly stressed the axle beyond its limit and "reversed" the camber on my axle, and after that my tires would wear out in a couple of short trips. It is possible that a road hazard has caused a similar problem with your unit. If your weights are okay, then it is time to start looking at the axle geometry to understand what is wrong. Just like a car, things can get out of alignment, especially after encountering a road hazard.

TWP723 09-01-2016 01:03 PM

I think you have the wrong tires on the unit or they're just worn and need replacing. I seriously doubt anything's wrong with the axles.

DanNJanice 09-01-2016 02:18 PM

I have a 27RLS with close to 10000 miles on the original "china bomb" tires. I do not see any unusual wear. If you are seeing the belts starting to show at 7000 miles, then IMO something is wrong. I would do as others have recommended, first check your weights, if OK, then start looking for axle/alignment issues.

Update and requested advice on Severe Tire Blowout
 
Hi and thanks all for feedback...it all helps. To recap, we were driving in Maine , near the end of a 2,000 mile, three week road trip, when a tire blew to shreds on my Jayco x23b. As the very nice AAA guy was putting the spare on my left rear of a dual axle set, he pointed out We Had a much bigger problem....all the other three tires were worn right down to the steel belt showing, all on the INSIDE of the tires. So, we crawled to a tire dealer in Harrington,Me, where we met another super nice and honest guy who ordered four Goodyear ST175/80r13's for next day delivery. His price was LOWER than the Walmart online price!
Then, we limped into Bangor,Maine, to McKays RV , a Jayco dealer, who said he could take a look the next day, so we once again overnighted unscheduled.
Mike Sr, another super decent and honest guy, told us we were ok to drive the remaining 600 miles to my dealer in Ontario, but that I should get new axles and new tires , under warranty , the two year one from Jayco, once we got back.

We drove back all the way at 50mph or so on the brand new Goodyears, without a problem, but presumably with the tires wearing unevenly once again.

So now my trailer is sitting at my dealer's,waiting for inspection . Questions I have, begging for feedback:

1. The Dexter axle manual says that when all tires wear out on the inside of the tire,it's due to 'loss of camber' and alignment is the remedy.Anyone else had something like this happen to them?

2. Steve, Mike's service manager told me they don't do alignment, they replace the axles. Has anyone had any experience with axle replacement? We are still in the two year warranty period.

3. I am fearing I am going to get told there's nothing wrong with the axles by my dealer, who is fairly small and is having a trailer axle guy from down the road look at it. Can anyone suggest what would be my next step?

4. I've done a lot of reading about this and it seems there are tons of measurements that can be taken, but with my pea brain, I find it hard to understand what's what. If I get given a bunch of numbers, is there anyone here who can interpret them for me? Or can you tell me what numbers I should be asking for, with respect to camber, axle bend, etc?

5. Overloading was not and never has been an issue with my towing. On the day when the tire blew out while driving, there was not more than 400 lb in and on the trailer, including propane tanks and batteries, and my side sticker says my max is 572 added lbs. We've never ever had enough extra weight in the trailer to get anywhere near that. Would anyone agree with me that when all four tires wear all evenly in the same place down to the belts exposed, overloading in this scenario is anyway highly unlikely ?


6. Ever since we got the trailer, I've noticed that the rear tires are tilted off-vertical when parked, especially when parked on an angle. I've always been told 'that's normal'... Anybody else ever noticed this degree of 'camber'?

7. Some would say, well you should have noticed that when you periodically checked your tires. A month ago when I was towing home thru my city, a guy followed me home to tell me he thought my tires were 'bent on an unhealthy angle' while driving. He and I both looked from the back and it was noticeable but not excessively while parked. We certainly didn't see any belts showing on the tires. I called my dealer the next day and was told 'that's normal. Also when I tightened all the wheel lugs before leaving for this recent trip , I never noticed any wear on the inside of any tire. Either it wasn't there or its in a place when you just can't see it without pulling the tire off. My question here is, how long would it take for all 4 tires to wear this badly... A long period of time, eg 10,000 miles, or could it happen in just a few hundred miles of driving?

Sorry for the length, but my reading of these forums tells me there are some very intelligent and knowledgable folks out there who can help me get through this. At the very least, we've all been there (or somewhere around there) and done something like this. If You are one of the experts on this, or have had a similar experience, please post?

DanNJanice 09-04-2016 10:17 AM

IMO, if the tires noticeably tip out at the bottom (or top for that matter) something is wrong. I have heard that trailer axles are designed with a bow in the axle. When installed in a trailer, the trailer weight flattens out the axle to its proper running position. If the axle is installed upside down, then you get the excessive angle of the tires. I have no experience with this, I just heard about it on these and other forums.
If you keep getting the "run around" try taking the trailer to someplace that specializes in repairing all types of trailers.

Jhowemca 09-04-2016 10:56 AM

I'd say if a good samaritan took the time to follow you home to tell you something looked wrong with the tires, then there must be something very wrong. That happened a while before the blowout, so it's been going on for a while. Not something that just happened the last few hundred miles.

I know you said there was no way the trailer was overloaded.
Without knowing that, I would say the axles have both been overloaded causing them to bend. 572lbs comes easy.

The other thing it could be is the wheel bearings. We still don't know how old the HTT's is. I assume it is pretty new as you mentions the warrantee is still in effect.
After the first few hundred miles did you tighten the wheel bearings?
Something that's often overlooked that the dealer should be on top of but usually is not.
Most of the time it doesn't cause a problem, a lot of people only put a few hundred miles a season on their trailers so when they have the wheel bearings repacked after a season or two they get tightened then.

You are racking up miles faster than most so if this is a new trailer that never had the bearings tightened it could be the cause of the problem.

Any new trailer, or new axle, or new hub, or new bearing needs to break in. Then be re tightened.

Good luck!

The Logans 09-04-2016 10:59 AM

I think that Jayco will do right by you... If what the dealer tells you after the inspection isn't what you want to here, contact Jayco directly!! It's not unusual for the communication between the dealer and Jayco to get a little, well, confused.

Jhowemca 09-04-2016 11:09 AM

When I tightened my wheel bearings after about 400 miles they were loose.
With the tire off the ground and grabbing the tire at 12 and 6 o'clock I could rack the wheel 1" top and bottom.

So if you've driven thousands....

1. The Dexter axle manual says that when all tires wear out on the inside of the tire,it's due to 'loss of camber' and alignment is the remedy.Anyone else had something like this happen to them?

Yes, on our 1007 pup. This isn't 100% the same as your situation as the pups have "normal" axles. You actually have Torflex axles that are more integrated into the frame.

2. Steve, Mike's service manager told me they don't do alignment, they replace the axles. Has anyone had any experience with axle replacement? We are still in the two year warranty period.

We had two choices, replace the axles, or find a truck repair place that does alignment on large semi-trailers that might try a much smaller axle. Unfortunately our repair shop could not find a replacement anywhere in Canada, so after much discussion we decided to upgrade our TT after our Jayco dealer offered excellent trade-in value. He would get the part from Jayco US over the winter. FWIW - I was surprised at how inexpensive trailer axles are (when you can find them).

Note that an axle swap for you won't be quite as easy as a standard axle because of the way the torflex mounts. a standard axle is literally four bolts.

3. I am fearing I am going to get told there's nothing wrong with the axles by my dealer, who is fairly small and is having a trailer axle guy from down the road look at it. Can anyone suggest what would be my next step?

I would probably get down on my belly and take some pictures that clearly indicate the toe out of the wheels. Then approach Jayco and see what they say. The toe is going to be pretty obvious if someone actually stopped you to comment.

4. I've done a lot of reading about this and it seems there are tons of measurements that can be taken, but with my pea brain, I find it hard to understand what's what. If I get given a bunch of numbers, is there anyone here who can interpret them for me? Or can you tell me what numbers I should be asking for, with respect to camber, axle bend, etc?

Dexter has manuals for this, but I expect different numbers for different frame/axle combos. I wouldn't sweat the numbers too much

5. Overloading was not and never has been an issue with my towing. On the day when the tire blew out while driving, there was not more than 400 lb in and on the trailer, including propane tanks and batteries, and my side sticker says my max is 572 added lbs. We've never ever had enough extra weight in the trailer to get anywhere near that. Would anyone agree with me that when all four tires wear all evenly in the same place down to the belts exposed, overloading in this scenario is anyway highly unlikely ?

IMO the only thing that causes this inside tire wear is axle de-camber. okay, the loose bearing is possible too, but I expect that would cause a lot of heat problems and shimmy alongside. There are two probable causes for the de-camber; either constant overloading or road hazard (that's what happened to my pup). Just like your car can lose alignment after hitting a pot-hole, similar things can happen to your trailer. As you said in your first post, you were driving a very bumpy road - do you do this often? Note that overload will correct itself by unloading the TT. If you still show off camber with all your cargo removed, then the problem is more likely to be a bent axle.

6. Ever since we got the trailer, I've noticed that the rear tires are tilted off-vertical when parked, especially when parked on an angle. I've always been told 'that's normal'... Anybody else ever noticed this degree of 'camber'?

When you say "off vertical" do you mean camber or caster? Often when backing into a tight spot, your tires will appear to have an off caster (side twist) from the turning forces while backing. If at all possible, it is best to unload the tire forces by finishing with a short straight back or forward movement. A bit of camber-in (tilting in at the bottom so the tires are a bit to the outside edge) is normal in an unloaded trailer and should flatten as cargo is loaded. Camber-out is not normal.

7. Some would say, well you should have noticed that when you periodically checked your tires. A month ago when I was towing home thru my city, a guy followed me home to tell me he thought my tires were 'bent on an unhealthy angle' while driving. He and I both looked from the back and it was noticeable but not excessively while parked. We certainly didn't see any belts showing on the tires. I called my dealer the next day and was told 'that's normal. Also when I tightened all the wheel lugs before leaving for this recent trip , I never noticed any wear on the inside of any tire. Either it wasn't there or its in a place when you just can't see it without pulling the tire off. My question here is, how long would it take for all 4 tires to wear this badly... A long period of time, eg 10,000 miles, or could it happen in just a few hundred miles of driving?

Once I hit the road hazard, I destroyed a new (beginning of season) set of tires in one trip of about 500km. It did not take long at all! My guess would be that you hit a road hazard about two trips ago based on timing and comments you made in your post - large swale or speed bump with all 4 axles. Do you recall such an incident?

Sorry for the length, but my reading of these forums tells me there are some very intelligent and knowledgable folks out there who can help me get through this. At the very least, we've all been there (or somewhere around there) and done something like this. If You are one of the experts on this, or have had a similar experience, please post?

The above are my opinions based on personal experience. They may or may not represent your actual situation - just trying to sleuth it out from what you have posted.

Note also that the 23B has the lowest CCC of all of the Jayco HTT's. Your axles are pretty close to capacity before you start loading - this was a design tradeoff that Jayco made. Actually Jayco often makes this tradeoff to keep the towable weight down and attract more buyers. It is even possible that your TT was damaged when delivered - perhaps a road hazard on the delivery trip to your dealer. PDI isn't so stringent that it will catch this kind of thing. If you find you have to swap out the axles, give some serious investigation to installing a different heavier load axle if at all possible. There will be less likelihood of a recurrence.

Good luck!

tires
 
I know kinda off subject but anyone know what is the max pressure a tire should reach if cold pressure is 85 psi going down the road for an hour or so ???

norty1 09-05-2016 11:04 AM

It depends on many factors. Speed, ambient temp. , type tire, road condition etc.
on interstates at 60-65 mph mine run about 10-15 deg over ambient temp.

Thank you for this very valuable feedback! A few comments, using my numbers above to relate to what you said on each point:

1. It sounds like your dealer found it impossible to find a replacement axle. I was hoping that Dexter would just ship another pair of axles for me....not necessarily going to be the case, or were your axles maybe just 'Rare'? I too am in Canada...does that make it harder to get them?

Also, I did start a claim with my insurance company as well. Am I better off going with my Jayco warranty or with the insurance claim, is another question that I thought of?

5. Regarding thinking about some preceding driving experience, at the beginning of our trip, we drove thru Montreal on HWY 40 and they were the WORST roads we have ever driven on....the pavement was just covered in patches and dips and what all ....it was an hour of pure hell. We put another 1,200 miles or so going out to PEI then back thru Maine where this all happened. From your post, it sounds like that would be enough miles to wear the tires down to the belts?

7. That Montreal experience seems to describe exactly what you say here in point #7 feedback, with the miles you project being put on after the experience all compressed into the fact that we were at the beginning of a 2,000 mile trip.

A follow up request for feedback.... It is true that the wheel bearings are right about at the point where the Dexter manual says they need to be serviced...12,000 miles. You describe overheating and significant tire wobble as symptoms of that problem...on our trip back with new tires, I constantly checked the hubs with the back of my hand for heat buildup and never any.

Would this lack of heat in 700 miles, the fact that the hub/spindles showed no 'searing' or anything when the dealer was putting new tires on, and the fact that all four tires showed the exact same wear pattern to the exact same degree....does this rule out wheel bearings, or is it still a possible cause of what happened?

Thanks again for everone's time reading this and especially to the last poster!

Many RVs play the weight game; it seems especially prominent on some of the Jayco Ultralight HTTs. The x17Z plays it awfully close to the vest. The one I had years ago had about 300 pounds left after the propane tank, battery, and HW tank were filled. That's not a lot of anything to be honest. Its the primary reason I dumped the trailer way too early - I was afraid to put anything in it.

freemanbobj 09-06-2016 08:40 AM

You raise an interesting concern here... And to add to it, all the brochures and online specs for a 2014 Jayco x23b state the GWVR as 4995 lb , with CCC of 995 lb.

Yet I'm pretty sure that the sticker on the side of my trailer says 572lb CCC ( don't have it in my driveway, it's at the dealer's)

What's up with that?? Anybody else have two different numbers like this?

Lolead 09-06-2016 10:36 AM

One way to check camber is with a carpenters level, The trailer must be parked on a hard, level surface and this will not be anything exact. Simply place the level against the tire, although the wheel rim would be much better, as vertical as possible. Now you should be able to tell by the bubble if the wheel is out at the top, positive camber, or out at the bottom, negitive camber. I would check each wheel against the other, this should tell you if something is amiss in the axles.

Sorry for the confusion on my part. My trailer tires run 100 psi cold and increase in pressure and temp accordingly. The psi goes up also according to speed and ambient temp. I have seen them as high as 117 psi in very hot , 100 degree ambient temps.

My TPMS is set to alarm at over 20 psi high. They have never gone over that.

The truck tires run 60 and 80 psi and also track those same parameters.

A little bit harder to get one in Canada perhaps. No my axle was not particularly rare: '08 Jayco 1007 pup. My Jayco dealer service department is about 45 minutes away on the other side of the city. My servicing dealer is not a Jayco dealer, but is a large dealer 10 minutes from home. The service advisor there came from my original Jayco dealer a few years ago and knows the line well. They were looking for an axle "in channel" from Dexter in Canada with no success, it was also late season. Eventually they could have gone to Dexter in states, but time and cost become an issue.

Also, I did start a claim with my insurance company as well. Am I better off going with my Jayco warranty or with the insurance claim, is another question that I thought of?

I would pursue both; Jayco is pretty good at goodwill. They may step up. But if you think that it was a road hazard, your insurance is the better way to go.

5. Regarding thinking about some preceding driving experience, at the beginning of our trip, we drove thru Montreal on HWY 40 and they were the WORST roads we have ever driven on....the pavement was just covered in patches and dips and what all ....it was an hour of pure hell. We put another 1,200 miles or so going out to PEI then back thru Maine where this all happened. From your post, it sounds like that would be enough miles to wear the tires down to the belts?

I think it depends on how badly out of alignment the axle is. Certainly was more than enough mileage for mine, but the alignment problem on our pup was very noticeable if you really looked at it.

7. That Montreal experience seems to describe exactly what you say here in point #7 feedback, with the miles you project being put on after the experience all compressed into the fact that we were at the beginning of a 2,000 mile trip.

You want to repack your bearings long before you get them so dry that they overheat, so yes, follow Dexter's recommendation. We don't do high mileage, so I tend to do mine every other year, but most people recommend every year. I would think that loose bearings as described would be more likely to lead to pitting of the races. Scoring, heating and scorching would be more related to too dry or too tight. Loose or too tight bearings are generally caused by a poor technician; once adjusted, the pin or retainer in the castle (or castellated) nut should prevent them from changing adjustment.

The fact that everything is wearing evenly is what leads me think it is an axle issue. Bearings usually fail or are mal-adjusted individually, leading to a problem with one tire, not all. With a standard axle, a broken spring might be to blame for rapid tire wear, but Torflex doesn't have springs.


Thanks again for everone's time reading this and especially to the last poster!

Good luck with the your situation. Get this taken care of before you wear out the new set of tires.

What's up with that?? Anybody else have two different numbers like this?

The brochure number is based on a completely empty trailer and no options. The number on the trailer sticker is based on YOUR unit as it rolled out of the factory with all options added and full propane tanks, but no water.

These manufacturer numbers do change over time as well. I based my comments on 2011 model because that's the brochure I have. In that year the 23B was rated GVWR of 4950 and CCC of 780 lbs. I suspect the axles on your 23B are the same as on my 19H as the GVWR (in 2011) was identical for both.

We had a 256RKS that we had a similar situation happen. Driving on I-40 to the Grand Canyon was rough with lots of construction and pot holes. Once we returned home, about 1000 miles later, we noticed one of the rear tires was worn down to the steel belt on the inside. We immediately replaced the tire and kept the old one for reference. Our dealer took one look at the trailer and asked if we knew how we had bent the axle. The only thing we could relate to was back to the rough road on I-40 even though it had not seemed that rough. He immediately asked who our insurance was through and started the insurance claim. The insurance adjuster approved the claim without any questions. The axle ended up costing $1250 of which we just had to pay our deductible of $100. Since the trailer only had about 3000 miles on it they simply transferred the brakes and wheels to the new axle. Never would have thought to file an insurance claim without the dealer's suggestion.

Thanks to all for posts ... Okay so my dealer says axles are bent and is waiting to hear from Jayco. Here is my hopefully next-to-last question:

All four tires were worn down right to the steel belts on the inside but otherwise had lots of tread on them.

On four new tires we did drive home some 700 miles without ncident.

Question: is there any way to determine when this bent axle condition was introduced , if we have put 10,000 miles total on the trailer.... Shipped from factory? After 1000 miles? After 9,000 miles?

You might guestimate based on your 700 miles if there is noticeable wear already on the new tires. If the inner tread looks to be about a quarter gone compared to the outer after 700 miles, then wear through might take about 3000 miles. But that would only be a wildly rough estimate.

Hi there , if you’ve been following my x23b saga, you will know that we found all 4 tires worn on the inside down to the steel belts. As predicted, my dealer is telling me that I overloaded the trailer and bent the axles.

Which led me to ponder the life of my trailer on this earth since I first laid eyes on it, almost tearing up as I do, Kleenex at hand.

We had our trailer for 22 months. For 19 of those months , or 85% of the time, it sat in our driveway, unloaded.

For about 60 days, or 10% of the time it sat in a campground.

About 80% of that 60 days, we were inside our trailer. That's 400lb of weight.
During those camping days too you can assume that on average, each of the water tanks was half full, so 50 gallons total at 10lb == 500 lb. Add in the allowed 632lb of CCC, so while camping on a site, the trailer was theoretically loaded with at least 1532lb, on average.

So to capsulate its short life, 85% of the time the trailer sat almost empty, in our driveway and 10% of its life it had more than 1532lb of weight on its axles, while we were actually camping.

Finally the last 4% of its life was spent 'on the road', with more than 632lb theoretically loaded into it. I've tried several times to add up rugs,chair, food,lpgas,batteries,tools,power cables,blankets, mattress covers, sundries and just can't get well past the 632lb allowed , enough to cause both axles to sag downward during that 4% of the trailer's life.

No matter. Does it not seem more reasonable to assume that the axles bent or sagged downward when the trailer was its heaviest for the longest period of time, that is the 10% of its life when we were inside it camping?

So, is Jayco telling me that they are happy to sell me a Jayco X23b light weight trailer and take my 20$k, but that I should never expect to be able to sit in it or actually Use it for camping??

The best answer to this is that you have the stab jacks down when you are in the trailer camping. They will be taking up much of the weight from living in the TT, not the axles.

You need to weigh the trailer on a CAT scale. No amount of guessing at weights will tell you what you need to know.

Weight adds up really fast!

And I really doubt your axles got bent sitting in a campground. As mentioned above you would have had your jacks down and even 1500lbs static load is probably less stress than 600lbs load bouncing around going down the highway and over bumps.

Hopefully your warranty covers you. Although it might not if the dealer thinks you overloaded the trailer.

Cheers

You may need to see if your tires are inflated properly.
If you haven't weighed your trailer, you should be running your air pressure at the maximum cold pressure. Typically on a 15" trailer tire it is 65 lbs.

I teach tire safety seminars all over the country. If you have questions please do not hesitate to contact me. I will be happy to answer your questions.

You will get all sorts of comments on forums. Most of the time they are very accurate but sometimes...

Let me know if I can help
