A cause for tire blowouts?

I believe that uhaul runs a bias tire on their trailers. They also post do not tow over 45mph all over the trailer.

Anybody know what tires U-Haul uses on their trailers?
Friends picked up a brand new 6x12 from U Haul. It was dark out and it didn't occur to me to look at the brand, but those were some hefty tires. Didn't look like your typical ST trailer tire judging by how deep the tread was on them.

Obviously, RV and boat trailer manufacturers are simply willing to take the cheapest way out. On the other hand, many people with tire problems have them under inflated and are not always careful going over curbs and railroad tracks.

Have you tried to find high quality ST tires locally? I don't think that there are enough good ST tires in North America to service the industry. The manufacturers have to go to China because not enough North American tires have been built. Great tires for heavier trailers are Maxxis M8008's, Goodyear G614's, Bridgestone R250's and Michelin XPS Ribs. (Some are LT 10 ply truck tires.)

I'm switching over my new trailer tires to Bridgestone Duravis R250's, and there's a $70 rebate until 8/6/2014.

I have ST tires on my trailer and always have.

I have had Goodyears and China junk and anything in-between on my trailer. All most always at 70+ MPH. In Utah at 80 for hours at a time in hot weather this summer.

One blowout in my life. Almost certainly a low tire nail deal.

So no, I don't believe they are hurting tires.

Tires blow for many reasons.

Last year I used my spare for about 50 miles, put it back on the spare rack and it blew up one day, just sitting there.

The culprit was mostly age, but it's hot, cold, you run over stuff, etc. etc.

I kind of believe that tires are cheaply made, but as to proof of why they fail when there's so many different things...

That's a good point Winged One... never thought about that.

On our last trip, 6 states, 3400 miles... I saw more than a few fivers and TT's pass me up (and I was doing between 63-65) like nothing, and thought well, they are probably some people who will later complain about cheap tires blowing up.

Regardless of the reason for 65mph, that is what they are rated for, and unlike other ratings, there is nothing that will increase that rating. I guess I'm just not in that much of a hurry while towing to feel like I need to do 70 or 80 down the highway, meanwhile risking over-heating the tires.

I find it interesting that the weight police are so adamant about the ratings manufacturers indicate for weights and say we should all stay well under those weights, but when it comes to tires, the China Bomb police totally discredit the speed and weight limits on tires and call foul.

I have towed the stretch of I-10 between California and Phoenix at over 75 MPH (the posted speed limit) many times with the factory GY G's on our heavy Mobile Suites with no ill effects. Also have done the same with the GY H's I have now.

Kinda sucks coming back into Cal where is limit is 55 for trailers, feels like you are crawling!

the delivery drivers are paid by the mile (one way) and not by the hour .... the bottom line is they really don't clear much money per trip so they have to make as many trips as possible .... that doesn't excuse exceeding the speed limit but it does provide a motivation .... they are liable for damage done while in transit .... I don't know if they would be held liable for a damage from a tire failure while .... I have seen campers with axles not properly aligned that literally wore the tires out while on the way from the factor to the dealership

So the LEO's look the other direction in all the states that they pass through?

Wouldn't commercial haulers that consistently drove that fast would be racking up tickets and have insurance problems?

The whole 65MPH speed restriction to get the inflated capacity rating is the root of the problem. A trailer that weighs 14K to 15K on cheaply made tires that weigh 35 pounds. It just does not compute, we would not accept this with a new car or pickup, so why do we accept with a 60-80K new trailer?

I hear that some manufacturers are now installing the LRG Sailun S637's. I know that are Cardinal club has gotten Cardinal to offer GY G614's as a factor upgrade.

I have also wondered about damage during delivery and also from sitting on the dealers lot or at home. Some of Goodyear's recommendations for tire storage including on a vehicle require some effort that I am not sure dealers or even some owners go through.
