Trailer tire pressure?

[yelbike]

It's been 20 years ago, but I know at least a couple of manufacturers who said to never run less than 80% of the rating on the tires. Forget what the door post number shows. So with 80 on the tire, you were good at 70; could go as low as 64, but to run then at 40 is probably just asking for a tire failure.

I think i just had the wrong tires really. LT E rated on a 1500 tahoe was overkill. I wonder if the low pressure led to early tread wear as I wasn't impressed with the wear. I got about 60-70km out of Good year dura track. 265/75/16.

Probably right. In the early '90s, some 3/4 ton GM pickups and suburbans came with some Uniroyal tires rated for 80 psi and door stickers for 50 psi. The ones I saw had bubbles on them from the rubber separating from the cord. Even though Uniroyal said it was from running them underinflated, we were allowed to warranty them.

My F350 dually 4x4 crew takes E rated 16" tires...
Max inflation is 80#...
I typically run the fronts @ 70# and the rears @ 50#...
Unloaded @ 80# all around will jar your teeth...

I had the opposite problem...My truck had GoodYear Eagles that GMC said to inflate to 30psi...The dealer inflated them to 40 after a warranty wheel replacement and all 4 centers started wearing off before I noticed it...Deflated to the door sticker and the wear stopped..This was most likely aggrevated by the fact that my tires are almost a foot wide. Sometimes the guys that built the truck know the numbers....I never follow the max sidewall pressure on anything and I've never blown a tire in my life....I follow OEM instructions--give or take.

I've never blown a tire in my life....

Fortunately, tires have improved so much that actual blowouts are rare now; they do happen, but not nearly as often. I've only had 2 in my life; a right rear on a '56 Merc doing over 100 mph in '58 and a left front on a '66 Chevy doing over 100 mph in '66.

Quick note...
I definitely don't see many trailer tire problems as there were years ago.
Maybe because when they let go, there is nothing left to inspect after you pull off the highway.
Carlisle is a good brand.
Bias seems to last longer than radials.
Many people either over-load the trailer and or under pressurize the tire.

Boy, you must work for Carlisle. I maintain about 75 trailers and they are by a long shot the worst. The newer Goodyear Marathons are not any better and bias tires bring on a whole other set of problems.

On our trailers we run Greenball Towmasters or Maxxis along with a few sets of Gladiators. All in radial with quality metal valve stems, tires balanced, and ran at max inflaton with no issues. All are changed after 6 years of service no matter the miles unless they wear out earlier. Average trailer gets 5,000 per year and during long layups they are placed on jack stands unless empty.

These are all 10,400# to 25,000# gvwr trailers with the vast majority being tandem and tri axle 6,000# Dexter and Alko equipped axle trailers.

Bias last longer than radials? I assume this is a typing error?? The exact opposite has been true as long as I can remember.

am i the only guy that runs correct load rating trailer tires on a trailer?

I see other peoples trailer with (P) passanger series tires on them..

+1
I run load rated (greenballs) on my trailer (80psi)

I got to say that the Greenball's and Maxxsis are by far the best that I put on my 30' fifth wheel...
Numerous blow outs with the Carlisles...
I've got both in radials on my camper now and have not had any issues...
