Goodyear Endurance Tire / Pressure

[switters]

I just read this and a bunch of other threads on tire pressure. I have a FC 23FB with the GYE ST225/75R15. It seems from Goodyear's own load information chart that at 65 psi I would be rated for a load of 10,000 lbs. with 4 tires. Since the GVWR of the 23FB is only 6,000 lbs., wouldn't this be plenty in terms of pressure and a good compromise between maximizing fuel economy and going for a decent ride/less shifting of contents in the trailer?

I bought a TST TPMS and I have to decide what upper/lower pressure limits to set on the sensors (as well as what tire inflation I want to start with cold).

You might find that a bit firm for a 23’ @6,000 lbs (which is more like 5,250lbs (ish) weight on the axles after you remove tongue weight which falls on the TV.

My 30’ loaded has 7,500 lbs on the axles when hitched and I run at 65lbs for what it is worth.

I run our 2020 28 International at 78 PSI per the dealer recommended and as set by them when we rolled from the dealership. In the Summer here in the Carolinas it easily gets into the 90+ degree range which drives my PSI up significantly into the 90s.

Cold inflation pressure is the only one that matters.
(With an exception of underinflated tires which heat up excessively)
All tire manufacturers know and understand the inflation pressure increased when the tires are used in service and that is OK.

My guess is your original tires were a 65 psi rated tire. Your new tires are load range E and 80 psi rated.
I run 80 psi, which matches the door sticker

On my 2020 25RB I start at 65 PSI cold on my Goodyear Endurance tires. On the road they reach 75 to 80 PSI depending on the heat by the end of our daily trip traveling through Montana, Wyoming, Colorado, New Mexico and Texas in July and August.

Based on the Goodyear chart they say 45 PSI cold based on my weight. I am not willing to go down that low, so I figured 65 would work just fine. We've logged over 8K miles doing this and zero issues thus far.

Just scrolled thru all the comments on this thread and looked at the Goodyear tire information. I didn't notice any comments on exceeding the tire rim limits. If one cleans all the brake dust off the inside of the rim there is a note to not exceed 65PSI on my aluminum rims. Goodyear plainly states this on the printed info.
I have been running my Carliles at 70psi

So the reason for my post is these GYE were first introduced in early 2017. How has the performance been? Blowouts, maintain air pressure when stored, uneven wear?

My Carliles have been on for 3 years now and am going to replace them soon.

I HAVE USED ALL THE OTHER BRANDS OF TIRES ON MY TRAILERS OVER THE PAST 15 YEARS AND AM CURIOUS AS TO THE PERFORMANCE OF GYE

Rim engineering is complicated like most things. The weak point will be the stem and is designed to fail first. So You will want to replace the stems if they were not replaced to match the tires. The rest of the rim will be over designed with respect to pressure and for aluminum rims you can go to 80 or even 100 psi with the proper stems.

Online reports about the Endurance has been good to excellent. I have not seen any reports of unassigned causal failure but they don't have many years so it is still early.

Great. Even wear (or no wear) Don't seem to build up much heat (+9psi)

Blowouts

Nope!

Yes!

uneven wear?

Nope.

I'd buy them again. I kept the 15" rims.

I bought a TST TPMS and I have to decide what upper/lower pressure limits to set on the sensors (as well as what tire inflation I want to start with cold).

When we had our 1975 Overlander, it had a GVWR of 6200. I ran Load Range C Yokohama LTs (no longer available) at 45 to 50 psi (which was their maximum) and never had an issue.

Load range D tires are 65 max, and Es are 80 max. This does not mean they need more air pressure to carry the weight.

I run 55 psi in the GYEs on our 22FB and the tires run cool. If I had a 23 tandem axle, I wouldn’t go over 50.

My GYEs are 3 years old now and about 18000 miles. Normal wear, no significant loss of air, balanced nicely.

I run them at 65 psi and things stay put inside and no rivets are popping.

The new Defender Michelin with the same specifications says 2,271 pounds at 50 psi. Andy still recommends 44 psi for the new version of the tire for his installations.

My TPMS reports that is a good number from the heat rise in the tires.

The lower recommended pressures guidance applies best to smaller tow vehicles towing relatively large trailers, the combinations Andy most frequently sets up. Pressures near true load on the trailer tire give higher cornering slip, so the trailer tracks a bit wide reducing lateral forces on the rear tow vehicle axles in hard turns. This helps reduce oversteer instability common with these overweight setups. However this also complicates the high inter ply sheer multi axle trailer tires experience thus increasing risk of ply separation so be aware of the trade off. If your tow vehicle is near or over capacity (its unfortunate I have to even say over) near minimum pressure may be appropriate, if not give yourself at least 15-20% or more load capacity with at least a few extra psi and reduce tire failure risk.

I also run 65lb on my GYE’S and no issues
1975 27’ Overlander

Thanks, everyone. I set them to 60 psi and drove from northern Utah to Zion yesterday. They got up to 70-74 psi while driving in 95 degree temps. Felt like a good, smooth ride. Fuel mileage might have been a bit worse than when the tires were at 75-80 but definitely less bouncy.

I finally wised up and bought a TST for my 25' Intl Serenity. When doing set-up I ran into questions about setting the maximum temperature alarm and the pressure ranges. I see a lot of debate here. I've always run at 80PSI following the sticker on the trailer, but the conversation has me considering a conservative decrease to 75. My question mainly relates to temperature. Should I leave the default in place or adjust the high temp alarm. I'm running stock Goodyear Endurances. Thanks all in advance.

I checked with my Airstream dealer and called Goodyear. Both said follow what the manufacture sticker says which is 80 PSI. Dealer said that 75 to 78 would be fine also.

This is my understanding: Generally speaking, higher pressure in tires leads to lower temps at highway speeds and visa versa. Lower pressure means more movement in the tire materials and that results in the extra heat. I don't know that 5 psi makes that much difference, but if you are thinking that running lower pressure results in less heat, I believe that is wrong.

The GoodYear tires do NOT say "Inflate to 80 psi". Instead, they say, "FOR MAXIMUM LOAD, inflate to 80 psi."
Are you at the load limit? What is the load limit? Look at the weird GoodYear inflation chart.
Maximum load for 225-75 x15 is 2830 pounds. Multiply by 4 tires and you get 11,320, add tongue weight (not on tires) and you have a GVWR of roughly 12,320 pounds.
Are you telling me that your Flying Cloud 25 weighs 12,000 pounds??? No? Then you're not at the maximum load.

I inflate to 65. Why? I made it up just like everyone else.

Don't make up stuff. That can lead to a bad vacation.
BTW the OP does not have a FC. The trailer is a 30' International.

There should be vehicle manufacturers label. Especially for a 2020 model. In this case the manufacturer is Airstream. The trailer will have a label, sticker or placard on it. Similar to the attached. May not be in the location shown. May be on the forward frame section. The owners manual may show location as well as same label.

Tire manufactures have inflation tables for the tires in generic use. Not knowing what vehicle it will be used on. The vehicle manufacturer has a specific vehicle design when tire pressure is specified. And different loads do make a difference.

Let me see if I can catch you up. A few years ago Airstream went from recommending something like the 65psi on the placard you attached to 80psi, which is the maximum pressure of the OEM Goodyear Endurance tire. Apparently, the higher pressure reduces harm from something called interply shear (search for that phrase on this forums), but is, obviously, well in excess of the Goodyear load carrying charts pressures. Goodyear has said its inflation charts are under review and so it is hard to tell what is right. Me? I'm like you. My placard says 80psi and that is what I use. Some say that is unneeded and too harsh on trailer and contents. Some say Airstream knows what is best.
