My tires are fine at 25psi. I am not going to sue anyone for a tire malfunction becuase I am running less air than Jeep recommends. At 33psi which is recommended by jeep I was wearing the centers down. I dropped to 25psi and have about 10k on them at that pressure and they are evenly wearing, the sidewalls show no extra buldging, extra heat or any other indications that they are under inflated. When checked hot they show 29-31psi which is a 50 degree tempuraturer inside the tire, which is what should be going on. Of course that changes when towing and I bump them up to 40 in the rear and 35 in the front for that. I regularly tow 3000+ pounds on a trailer behind the jeep. With 15k on them they still have 12 out of 16/32nds of tread left, evenly across the tire. I should manage nearly 60,000 out of these tires, based on 4/32nds of tread use for every 15k. ( of course we'll never know becuase they are comming off next week)
So if they are not the victim of too much sidewall buldge/flex, which causes more heat near the shoulder of the tire, and they are not running hotter than they should near the shoulder of the tire which cuases belt to sidewall speration, and bead retention isnt an issue what is going to be the cause of this blow out?
Radial ply ratings dont stand for the number of body plies, they only stand for the strength of the tire based on the old ratings of bias tires. In fact most LT trucks only have 2 or 3 ply bodies.
So why should a Load range e tire get more air than a load range c if you arent carrying more wieght other than for bead retention, which in my case isnt an issue?
