I shouldn't have used the word theory--I have to agree that Michelin should know what their tires are good for. And I am not a tire expert, just one who has driven over 70k miles annually for the last 39 years. Two blowouts in all that driving--just lucky, I guess. But
most of that driving is in pickups and cars, not towing trailers. But, have been towing trailers since 1979 and never have had a trailer tire blowout, believe that or not. Statistically, I am way overdue for a $$ disaster?
Looking at the Michelin and the tread depth and the weight rating, I am not worried that I might go over 62--or 65--or? I check pressures and temps daily--more often when I travel TX hiways in 100+ temps, and the tires have never seemed to get hot enough to worry that something is going to happen.
Now a near disaster was the DRV factory letting my trailer out the door when it weighed dry at 15815 with a 16000 GVWR and the 16" GY tires.
I didn't buy it new, but it is rediculous for the seller AND buyer to put a trailer on the road with 185lbs of cargo capacity. That is one of the reasons GY 16" tires were failing on DRV units, I think.
I have the 17.5 tires now, but still have the 7K axles--would like to change them out to 8K, but in THEORY, I am under the axle capacities.
