Tires

I have a North Point Bunkhouse with 255/85/16 Goodyear tires. 10 ply. I want to change to a 14 ply tire that is rated for heavier loads. I want to change to a 235/85/16 G rated. Can I make this change.?

That is all I have to say.

You don't indicate where you are located. If you have a Discount Tire or similar near you why don't you contact them and ask? You may get some advice here but to tell you the truth I would not change tires and drive off down the road on what I got as advice here. No offense to anyone on this site but few here are experts.

Keep in mind that changing to a tire that "might" be good for heavier loads will not increase what you can carry.

what is the gross weight of the RV? Is it materially more than the overall capacity of the tires? Sounds like you have the Goodyear 'Beast' tires already, which are well regarded overall. If you put tires that have a much higher capacity, keep in mind that generally also comes with a much stiffer sidewall, etc. Can result in a harder ride, both for you and the interior of the RV.

CAG is also correct that it would have no impact to the cargo capacity of the RV, as that has other dependencies, such as springs, axles, etc.

The proposed 235 tire is narrower than the oem tires. So, they will fit under the 5ver.

The real question, are the rims able to accept a narrower tire? There should be a label possibility on the backside or in the rim. If you cannot find it, contact Jayco with your vin number, they will have you contact the frame provider and they can tell you what rim you have. From there you will know for sure.

If you have a Discount Tire near by, they might be able to tell you.

Rims handle the higher tire pressure? I assume a load range G will take more than 80 psi.

have you looked at the weight rating on your current tires? Nothing wrong with them....I would keep them. Goodyear Endurance are good tires and they well exceed your axle rating and are speed rated to 87 mph

My 2015 323LKTS, 12,995 GVWR, came with load range E tires. They went bad in less than 2 years. I upgraded to same size in load range G, but they were so much larger they scrapped the wheel well. I had to life the rig by putting the springs on top of the axels. Since then, the Load range G tires have performed much better. Have a tire pro give you exact measurements on both the 10 ply and the 14 ply. It's kind of trial and error to see if they will fit on each different rigs. Also, finding out how much air pressure your rims are rated for is necessary.

you can put your two different tire sizes into the calculator and it will compare the size changes. https://tiresize.com/comparison/

the load rating of that Goodyear Endurance tire ST255/85R16 is 4080 lbs. at 80 lbs psi. The G rated tire is actually less at 3750 lbs. @110 psi

Look into the Sailuns S637; they are 14 ply, G rated, equal to the GY 614, but at 2/3 the cost of GY

LegalEagle · 03-02-2022, 11:10 AM

I forgot to mention, the 14 ply I purchased at Discount Tires are Carlise trailer tires. Have performed well.

Carlisle trailer tires were china. So they are US made now? Goodyear endurance were the only US made trailer tire. I'm curious about these US made Carlisle tires.

You are correct. While Carlisle tires has 2 manufacturing plants in Tennessee, their specialty tires, which include trailer tires, are still made in China. Sorry for the misrepresentation on my previous post.

Your wheels will be another determining factor if you can put on G rated tires.
My 17 Northpoint 375 has 10 ply E rated Goodyear Endurance tires on it right now with no issues. Before I put them on i considered G rated tires, so I contacted the wheel manufacturer to see if the wheels would handle it. They informed me there are stamping marks on the back that indicate weight limits and such. They did say my wheels will handle G rated ones because the G rated tires were an option anyway.
Check out your wheels.

Ok thanks! I thought they made a change that I didn't hear about. Far as I know the only ST tire on the market that is US made is the Goodyear Endurance tires. The only tires I haven't had blow excluding when I switched over to US made LT tires prior to the Endurance coming onto the market. I couldn't even tell you how many china bombs I had let go. My insurance company said it's a major issue with China tires when they paid out my claim for damage when the one tore the trailer all up. They said they can't get any recoup money from the China manufacturers.

What they do in China is when they have enough complaints they just change the name of the company.
Note the speed rating on made in China tires, most of them are below freeway
speeds. A lot of them do not have a speed rating.
My last 2 Jayco's had Goodyears.

When I went from the stock E rated (80psi) tires to the G rated 14ply 235/85R16 (110 psi) tires on my trailer I checked the wheels and they are stamped on the back 110 psi. I bet yours are too.

Also my Sailun S637 tires are rated for 4080lbs.

Over the years, I've finally had to quit buying Chinese tires. Learned my lessons the hard way with Goodyear Marathons and two other brands made in China. Very expensive blowouts on the highway, even sidewall bubbles sticking out an inch. Lots of camper damage. I do realize all Chinese tires aren't bad, maybe I've just had bad luck with them. But, not going to take a chance again.

I agree 100% that a lot of China tires are junk (like the ones that came on my trailer) but these Sailun tires are tough. I've run them for 7 years with no issues at all.

Glad to hear that! 7 years should be a good test. I'm sure all tires from China aren't bad, but I sure had a streak of bad luck with them.
