Tire Replacement Advice

[Papahoosh]

After 18 months of stationary, we decided to take the RV out for a 120 miles road trip. On the way back to our RV lot, I received a warning from the TPMS and pulled into an open parking lot and noticed our Goodyear Endurance started to separate (tire pressure was checked before leaving - very disappointing). Now, I am thinking about Sailun s637T G/14PLY, but the cold PSI is 110 and my other three tires are 80. I looked inside the rim and did not see what PSI I could use. Should I stick with ST235/80R16 E/10PLY Goodyear Endurance?
Note: during the 18 months of stationary, I was turning the tires every other month, so it wasn't on the same spot for too long. Any other good tires with similar specs as the GY Endurance out there? I really don't want to replace all four tires. I am sure I can't have one tire at 110 and the other three at 80 PSI. I read the PSI should be the same on the same axle.

If I found what you found, I would assume that the other three tires are in the same shape as the one that just failed. Just sitting in one spot for months and months is hard on tires, and Goodyear Endurance seem to be losing their luster, as far as reliability is concerned. I would change out all four if I changed out one, since it failed, basically, while it was sitting in place. In any case, I would want all four tires the same. Besides, unless you measure the overall height of the tire, you can't be sure it will be the same diameter as the rest.


And I wouldn't replace them with more of the Endurance tires. Sailun tires are rated, in the size you would use, at around 4,000 lbs. carrying capacity. Much more than you really need, but some feel that there's no such thing as too much tire. I'm not one of them.

I agree that all tires should be replaced. Not going to comment regarding brand or size.

Then you have to think, if one tire has come apart, what are the other 3 like. IMO, a lot depends on what trailer model you have and what the loaded weight is as to how much tire pressure you should run. Yes tires setting is hard on them especially setting on dirt, grass or any place they are setting in damp wet surfaces. Sun/heat is a determining factor also.

But in any event its a "real good idea" to run the same size, load range and #ply on the tires all around but for some owners not necessarily the same brand name. But Me, I run all the tires from the same brand manufacture. That's just me. We run Sailun on the axles but the spare tire is a Westlake "G" rated tire same size as all the others..

Now we have a Solitude, 16,800 GVWR, 7000 axles with ST 235x80xR16 Load Range G 14 Ply. I don't care what the speed rating is, never consider it, never look at it, always run 65-70 or below mph.
Loaded weight @ 16,000. So I initially run them at 105 cold. I would never run them on a Solitude below 100psi no matter what the loaded weight on them was, but that is just me.
Max load on our Sailun tires is 4080# each at 110 psi. That kind of 14 Ply tire on an Imagine for example is way overkill. But maybe on like a Reflection 337, yes.

We have been running Sailun tires now for about 4 years, love them.

Another vote for Sailun. We're on our second set only because I drove for over 200 miles on my first set after breaking a leaf spring without knowing it. It messed the tires up pretty badly, but they didn't fail. That told me that these are some pretty tough tires. I wouldn't put on anything else on the market right now.

You can always run them at a lower pressure if you don't need all of their capacity. If you do that, an added benefit is a little better ride.

One important consideration is what are your plans. If you are just going to sit in place for a couple years then wait and replace all four at that time. But if you're planning more road trips then consider the above recommendations.

Is the 110 psi that you mentioned maximum tire pressure rating? If so, look to see what the minimum rating is for the tire and stay above it. Look at the load rating for Goodyear Endurance in your size at 80psi. Apply enough pressure in Sailun to match the load rating for Goodyear Endurance at 80psi. Ride still could be stiffer with Sailun, even at a lower pressure, but I have no experience with Sailun including relative ride quality...

I'm impressed that you turn tires every other month, which should be quite helpful to tire life! I take most of load off tires when in storage through leveling system, but this is not normally reasonable to do. As you likely know, taking RV for a spin monthly goes a long way but is even less practical.

Finding pressure ratings on rims can be a challenge...

Your wheels are rated for 3300 lbs (that is stamped right into the wheel). I did not see max psi. At 3300 lbs your maximum tire pressure is probably 80 psi. I would call the wheel manufacturer before you do anything

I'm on my 2nd set of Sailun S637. First set was 4 years old and never had a problem, only changed them because they were 4 years old. Had about 27,000 miles on them. 2nd set has been on for 2 years and still have never had a problem. Have about 15,000 miles on this set. It is the only tire that will go on my trailer. Trailer weighs 16,500 pounds with 3,000 hitch weight. I run them at 100lbs cold.

When I store my trailer, I put all the leveling jacks down, which takes some weight off of the tires. I also have Goodyear endurance tires. Considered going with the Sailun, but thought they were overkill. My next set of tires I’m looking into Hercules, which have more plus than a good year endurance. Maybe give them a look. Also, hopefully when you store your trailer, you’re putting wheel covers on the tires. If not, you should be. Goes a long way towards tire longevity.

We bought our trailer in August '23 and in November '23, at about 1,500 miles, we had sidewall failures on two of the GY Endurance tires (within 12 miles of each other). To say the least I am not a big fan. We replaced all 4 tires on the side of the road with same size and rating Carlisle tires and they have worked well for about 10,000 miles. I will probably upgrade when these tires need to be replaced as I don't like to operate so closely to the "max" rating. I like a bit more safety cushion.

 

[poohbear]

I had put Sailuns on our other 5er 3 years ago and I thought they did a great job replacing my GY's. I never ran them at 110 but did run at 90psi as the gvwr was 14500. The tire dealer installed them at 110 but the ride was terrible on the rv.
Our 397 has the Coopers on it and I was skeptical but they are doing great. many years ago I had a customer that was a Cooper dealer so I tried to shop there for my company vans. Those coopers left my techs on the side of the road often so had to find another brand.

Those wheels can't take a 110psi tire. If you are going to 110psi tire, get wheels to match. Or..if I were you..buy another set of 80psi Endurance tires. Or one if you only do a 120 mile trip every now and then.

 

[Chaps2018]

Good point! The rim’s max pressure should be stamped on the back side of the rim.

Also, you will want to check Sailun’s inflation tables for the proper PSI based on the trailer’s weight. You can reach out to them via website they are very helpful.

Tire pressure is directly related to load capacity per tire. If one tire has separated I’m not so sure I’d trust the others.
You can cry once, or cry 1000 times (okay, 3 times in this case).

I ran my first set of Sailuns for 6 years, and they were still looking good when I sold the trailer. IMO, you can't beat 'em. I definitely wouldn't get rid of them after only 4 years.

I might buy Sailuns in the spring. I have 4 Endurance tires from 2018 on my trailer now. I had the dealer switch the rims and tires from my previous trailer because I had 110psi Hi-Spec rims on it.
My six year old Endurance still look fine from the side but while replacing the bushing and equalizers I noticed cracks in between the tread blocks.
But I would never put 110psi tires on original factory wheels that came with 80psi tires without verifying the capability of the wheel.

 

[Lavarocked]

Sailuns were my replacement for my stock Goodyear tires, never an issue on my 312BHTS. Guess what I’m installing this spring on our 367 BHS how that the warranty expired on the Goodyears

 

[Joe1967]

I had Goodyear Endurance on my 31MB from the factory. After three years, they still looked like new from the side (less than 10,000 miles), but they were all splitting between the tread blocks.
