I merely stated the facts regarding the failures. I drove the rig to Alaska in '15, a total of almost 11,000 miles with no tire problems whatsoever. On that trip I ran them at 85 PSI (cold) which is a bit above recommended pressure. Recently, it was recommended by a local tire dealer that I should not run at more than 80 PSI (cold). I followed that advice. I'm now thinking that a little higher pressure would be better for the tires. I am running a TPMS and at 80 PSI (cold) have been seeing pressures of 90 to 95 PSI while running. As I recall, during our AK trip, running pressures were staying in the high 80's at 85 PSI (cold).
Tires are Load Range E, 10 Ply Rated and were on the MH when I bought it in late 2014. Date code shows they were manufactured in 2013 and at the time of failure had approx. 16K-18K miles on them.
BTW, the MH data plate states LT235-85-16 tires, Load Range E and 80 PSI.
Regarding the cupping. The tire shops that replaced the tires stated that they see cupping quite often on TOYO tires, but continue to sell them on price point.

Did you put the same tiers back on?
The thing you need to do is weigh your coach and get the axil weight's best practise is each wheel. Then you will know if your weight is corect or you are over on a given wheel or axel.
Alwas run/ajust your preshure to what the max weight is on that axil/wheel weight. Anouther way to say it is what ever tire is careying the most weight on a axel use that weight to set your preshure for that axel.
I would run the new tires at the max preshure on the sidewall till you have weights.
Heare is a link to the toyo tier preshure guide.

Interesting.... cupping or scalloping around the edge of the tread on one side or the other, almost always indicates worn or bent suspension parts. Adjustment of wheel alignment alone seldom cures the problem.

It has nothing to do with the tire manufacturer or manufacturing of tires, if I were you I'd start by finding a tire store that knows what they are talking about.

Hope you get it all figured out

Bill

I am with you I Don't think edge cupping has anything to do with the tire. A trip to Alaska would be a good place to bang up your suspension.
After re reading some of the OP's post I am wondering why would you put the same tiers back on if they were so bad??? I would at least go to a larger tire with a higher load rating.
