im running powerking lowboy 7-14.5 bias 12 ply tires on my trailer... i have lost count of how many tires ive had that have come apart. the tread gets chucked right off the tire. i think i was at about five tires.... just added two more after summerbash.. that makes seven frickin tires.. im lucky i made it to the house.
what gives? ive noticed most of the tires seem to go south on hot days. had three of them come apart on i84 on my way to idaho once.
any input? need radials? trailer alignment?
im kind of ruling out a mfg defect... lol..

Spend a little more and get radials imo.

Are you filling the air to the maximum pressure. I just put new tires on my trailer and Schwab told be to keep them at about 5-10 psi below the maximum pressure as they Will gain pressure when they get hot on the freeway. I know this pressure is stated when the tire is cold, and I know that the tire will gain pressure when driven, and I know this is what the tire should be made for.
But, when we aired our tire back up after camping on the dunes to drive home I filled my tires to 70 psi (80 maximum). When I got t the first rest stop on I5 the tires were at 85 psi. So I would guess that if I had filled them to 80 psi they would have been at 95 psi. So I would be Leary of having that much pressure along with a heavy load.
Just my theory.

Tire pressure rating on the side wall says cold psi because they know they gain pressure as they heat up. Dont adjust your hot psi to cold psi

I understand the cold hot thing. Just saying Les Schwab sugested keeping them a little lower.
Rockdog has new tires on his trailer and believe he had them up to max cold psi and one of his tires pealed a tread off.
I've never run powerking tires, but they could have had a bad run on them.

were the tires overloaded? I was losing tires for a while and just bumped up the weight rating and problem solved.

tread failures are usually manufacturing issues.

mine are dynatrail radials 1820 lbs that's 7280 total and last time I hit the scale it was 7400 with the crew cab on it. and about 7000 with the blazer so looks as if when these wear out I'm bumping up a range like Poorboy did.

With the Jeep in our hauler we weighed 11K on the trailer and 11K on the truck. So, that's just about maxed out. |

I ran within my weight range of the trailer but barely, the issue i think I had was if the truck wasnt loaded perfectly then one axle was taking more load than the other and there for overloading the tire. The new higher rated tires fixed the issue.

I run my tires at 50 psi cold. I was running pretty much maxed out with the blazer on them. I have yet to loose tire other then being warn out. And i for a side wall when i curbed it. I have had the trailer for 8 years and have put one full set of tires on it. I only buy radial because the the bias cup and hop real bad when it was empty.

100 sounds ok for 12 plys. could still be a heat issue depending on how the trailer tracks and how much weight is on a particular tire.

Those are moblie home tires they are a soft compond and also are made for limited use as moblie home axless are rated for one time use as most of there bearing have plastic bearing holder. On other hand my old trailer with i put a td9 dozer on and pulled my old scout on for years i never had problems with.there is a lady off johson creek that sells 14.5 tires i found her in nickle ads years ago sell moblie home axles i remeber ad saying ask for molly if it helps

If im understanding what ive read about these wheels/tires... Those are the only tires for those rims. You cannot buy a radial for a 14.5 rim... I have two spares for my trailer, that are radials, on 15" rims, when i test fit them on the trailer, i notice that the hub hole of the rim doesnt fit over the little "shoulder" on the wheel mounting surface of the axle. So the tire sits a little crooked and wobbles... Basically what im seeing is i have two options, Grind the 15inch wheels a little bit, so it fits over that shoulder, the tapered lug nuts will center the tire, theres seems to be no purpose for that shoulder/lip. Or get new axles, wheels, tires.... At that point, i may aswell sell my trailer and put a down payment on a new one lol... Im not too fond of the first option haha  |
