Should I replace all my tires of just 2?

niknak · 04-03-2021, 06:45 AM

My 2018 White Hawk 26rk is going on a trip from Wisconsin to Glacier in June. It has the Goodyear Endurance 205/75-14. They have between 7-9k on them. There is very little weather checking and no bulges, they also hold air really well. There are two of the tires that are around 4 and maybe even 3/32nd and the other two are 6 or 7/32nd. I'm wondering what is suggested or what you would do, just replace two or replace them all. I do plan on upgrading to a 5th wheel when the market settles down a little more or at least wait to see if it ever does.

2/32 is the rule of thumb. If they are equal on both axles I would just swap them front to back and then replace after the trip. If you decide to replace them I would definitely do all 4.

I should of added that I did rotate them already. Thanks

Also, the trip to glacier will be about 2500 miles

Thats a great trip, we did it a couple years back.

3 years old, I would travel on them. I was going to add I would rotate them, but it sounds like you did.

I would also grease the bearings before you go, if you, if you have never done it.

Age with trailer tires is more damaging than miles. Most don't travel much but do sit, get warped into funny angles while backing, hit curbs and sit in the sun on one spot on the tire for long periods. Dry rot kills tires faster than miles.

I have dealt with Discount Tire for 50 years. The general rule with most that I talk with there suggest three to four years for trailer tires due mainly to what I mentioned above. Three for standard tires, four for the top of the line tires. Your are living in a different weather environment that I and many will tell you that they drive much longer on a set. That's fine but my view is than a new set of tires every 3-4 years is worth what happens when one blows in the middle of no-where.

Thanks, I did grease and inspected the bearings last year about 1000 miles ago.

I'm excited for it, we live right on the mn/wi border.

Ya, I'm feeling like it's on the line of replacing them. The one advantage is that I would keep the best one or two for extra spares.

I really like the Endurance tires. I just wish they came with more than 8/32 tread when new. I have 12,000 miles on mine and they all are down to 3/32. I've also noticed that they have increased in price by about $10 (Discount Tire) over the last few weeks.

Ya, going up in price like everything, but that's fine, these have been trouble free for me on all our journeys. I'll pay the extra $10.

My $.02 worth. If one asks that question, it is time to replace all. Don't wait.

Okay...I guess.

Change every tire.
Doing so would give you peace of mind.
The Discount Tire store I use in Albuquerque says when the tread wears to 3 or 4 32nds, it's time to change. Not everyone agrees on those figures.
As others have said on this thread, the age of the tire is critical. Every tire has four numbers, inside of an oval, that tell you when the tire was manufactured. The oval is about an inch wide, a third-inch tall. It's on a sidewall. Usually, on the inside sidewall, which means squirming on your back to find it. A flashlight helps.
Examples of the numbers: 0419, means the tire was manufactured in the fourth week of 2019. A 3820 would mean the 38th week of 2020.
On our Melbourne, I changed all six tires this past fall prior to a 4,000-mile trip. The two front tires had excessive outer tread wear, due to never having been rotated. Tread depth was around 6-32nds, which means the tires still had some life. But I did not want to worry about tire failure.
We opted for Coopers, from Discount Tire. So far, so good, after about 10k miles.

If in doubt, change them out. Its not worth the trouble if you have a tire failure in the middle of nowhere. Glacier is a great place but some areas are a bit out of the way.

RV & boat tires age from sunlight and / or sitting on dirt surfaces.

Okay, thanks. Now to convince the spouse we need them after buying a lithium battery and portable solar panel.

If your lithium battery and/or solar panel failed you will still be safe. Just remember your safety rides on your tires

I know, it isn't sounding I take lightly. They just aren't that old and only the two have the lower than optimal tread. I also always put boards under them and don't let them sit on dirt.

EBCTrekker · 04-11-2021, 03:30 PM

I've always leaned toward being more cautious with tires. They are a pain to fix / replace if they fail in a bad spot. Not to mention the damage that can occur if something unusual happens such as a tread breaking free.

Tireman9 · 04-14-2021, 12:53 PM

Have you learned WHY you got different wear rate?
Is the wear uniform across and around the tread surface?

niknak · 04-14-2021, 02:13 PM

It is uniformed across the tread.

It would depend on tire load range for me, our 2018 Outback blew a tire on the interstate last October, we bought the unit new in January of 2019. The tires looked new but were load range “C” . I chose to replace all four with load range “D” tires, I prefer the heavier construction of the tire.
