Questions: Are folks running the PSI listed on the sticker for their RVs? Example: max cold air pressure is 80psi. Is this where you are setting the tire pressure?

Also, are you guys torquing your lugs to 100 ft. Lbs. or whatever the decal states above the wheels? Just validating. Mine states 80 psi on the Goodyear Endurance tires and 100 ft.lbs. on the lugs.

Yes... these tires turn into grenades easy enough as it is. Make sure that your cold pressure is what the sticker says. They will go above that in use, so not air down to try and get back to the cold pressure while hot.

My camper (36ft Grand Design Solitude) tires are also Goodyear Endurance (I got rid of the china bombs) that I run at 80psi and 130 ft lbs.

I have the 305RE, they are G rated tires on the camper.

OK, that prompts 2 questions.

When did GY start making G rated Endurance?

Why are they only inflated to 80PSI? (G rated would be 110PSI max)


ETA: Seems GY updated their load inflation chart and the 235/85R16 is rated to 110PSI through the rating classification is still vague.

Do you have a pic of the sidewall if that's the size you have? (I have 235/80R16 on my reflection and they're only max 80PSI.)

On your 235/80R16’s do you run 80 psi cold? Same tires I have. Confused a bit here. I thought the 80 psi on the side wall is the max, not necessarliy what they should be inflated too.

Load range E is 80 PSI max cold.

Best to run 75-80 PSI on these trailers regardless of load. If I was putting E rated tires on a lighter (under 12-14K) trailer, I would follow the chart closer and wouldn't run them at max, that would just beat up the suspension.

With truck/car tires it's best to follow charts and even the chalk test for even wear and best ride. With trailer tires, they usually age out before wearing out and you want them to run cool.

Great thing about these GY Endurance is they are ST tires (sidewall flex) yet carry an 87MPH max speed rating. I've been very pleased with the GY's.

Thanks for the info. I was leaning towards 70-75 psi to allow for growth due to temp.

Don't do that. Temp/pressure allowance is built into the construction and specs. Common mistake that leads to tread separation and blowouts due to heat buildup.

You have a 16K GVWR trailer running on E rated tires, put them at 80 PSI cold and monitor with a TPMS.

Absolutely. The engineers who design tires determine the proper cold inflation pressure for the rated load. You are expected to follow that information and cold fill to that level and not at all adjust down as the carcass warms.

But what the hell do I know. I'm just an idiot engineer at a nuclear reactor. Your all right, you know more than the design engineers and should do things your way.

I'm confused by your statements in relation to quoting my post.

On one hand, you agree with what I said. Then you imply that I recommended anything different than cold inflation. Perhaps you meant that jab at someone else.

P.S. It's "You're all right," ;)

Sorry, I was agreeing with you and smacking my head at the few posts above.

I use Skype typing on my phone, I don't care enough to correct a long as an average person can figure it out. I never saw the interest in going around correcting others and acting as grammar police. But it's cool, everyone is looking for some way or some thing that gives a feeling of superiority. I'm sure that each and every one of us has some thing that sticks in our craw.

ST are the best bad idea to come to the tire industry. Ever notice that trailer tire manufacturers and resellers are the cold who stand on the mountain tops crying the loudest about the benefits of the ST while farmers and other hard core people have been swapping to LT tires to fix the ST tire issues for decades? Coincidence? Kind of doubtful.

ST tires are a combination of marketing and bean counters. Get them made cheap, sell them high, market them as the best choice and convince the unwashed masses to literally buy into the line of manure.

You win. You have a large percent of trailer owners convinced that imported, light weight, cheaply produced tires are actually the better choice over a quality HD LT tire. Imagine being in the backside of that money farm!

You keep using the word "You" and throwing barbs about things I never said. Still confused.

The "correction" was a sarcastic response to your pontification. Forget I said anything.
 
I'm confused as all hell in this thread. I agree, ST tires are perfectly fine. I've been using them for decades and have hundreds of thousands of miles pulling with them. For the record, the ENGINEERS that design tires take into consideration the performance profile of intended use, which is one of the major differences. There's a difference in the forces applied to the tires with respect to acceleration and deceleration, as well as differences in sidewall stiffness. But hey, I suppose anybody can believe whatever they want. As somebody from a farming community, with a ton of livestock, and a ton of trailers, I guess we all lived in isolation and missed that whole switching to LT tires thing......
