Do more plies in a tire help prevent blow out problems?

6 ply Load Range C 2150 pounds @ 50 PSI
8 ply Load Range D 2150 pounds @ 50 PSI 2540 pounds @ 65 PSI
10 ply Load Range E 2150 pounds @ 50 PSI 2540 pounds @ 65 PSI 2830 pounds @ 80 PSI


For my trailer I would need the 2150 @ 50 PSI - would buying the tires with more plies give me more protection against the 'blow out' problems that are the subject of so many other threads? Or is blow out not related to the number of plies and max load rating? My present wheels will 'take' 65 PSI, so I could go with the Load Range D or E tires & the higher PSI, if that helped the problem. My inclination is to go with the D tires and run them at 50 PSI - is this the right way to go? The two extra plies over the C tires would give me some safety margin against a blow out?

Thanks in advance for your opinions & info?

Yeah! If you are going with 2150 then your problem with be solved. I am not sure but I think.

What I can't get over is the goofs who buy 6000 pound 454 cu in vehicles and complain about the mileage. Duh, what did they think?

Amazing some people. I feel like asking if they are stupid.

Thanks Vinnie

I just ordered the exact same tires (2) for my single axle '64 Safari. I will plan to run them at 65 or 70 psi. I will certainly report how they perform. At Discount Tire the Maxxis version was $30 more per tire.

If you have steel wheels that have been in service for an extended period of time, you must replace them when you increase the tire load range.

If not, they will split around the inner circumference, as per wheel manufacturers warnings.

That can happen going from "C's" to "D's" as well as going from "D's" to "E's".

Good to know, and I should have stated that I also ordered new Aluminum Wheels, also rated for 2800# each.

Good, now that worry is over, but "E's" are not recommended by Airstream.

Also, you should probably install the wheel balancers, since next to no one can balance the tire, wheel hub and drum, as an assembly.

I am very happy with these tires so far. We are staying in Grand Canyon right now and have traveled some rough road at high temperatures. I set the cold tire pressure to 65lbs. On the hottest part of the trip when i pulled over at a rest stop i checked the pressures and they were 71psi. So when they heated up they increased by 6 psi. I purposly put a few things on the counters while traveling and to my amazement they rode right where they sat. These trailers are amazing how they ride. There was a crazy section of I-40 that had rolling dips on the road. The sign warned of it but I had no idea it would be as bad as it was. I expected to find everything on the floor when we stopped but it was all intact and in good order. Even though the tires are load range E the trailer is heavy and I think they suit my application well. I hope they work well for you too.

Thanks Vinnie
