    Air bags leaked at different rates over the year as I chased the problem down. I think I finally have that beat. They are rated for more than they are carrying.

    My 3/4 ton Suburban runs load range E tires. And I have never had a set of any brand on it since 1995 that wasn't 80 psi loaded and 50 PSI minimum for unloaded ride quality. Ride sucks with 80 in the fronts but tire wear is a lot better.

    No you don't need to have a RAWR of 10k to take advantage of LRE tires. The typical LRE tire can only support around 3300# so a typical truck can overload LRE tires with as little as 7000# on the rear axle which includes the empty weight of the rear axle.

    My F350 has a RAWR of 6600 as I recall and is limited by the LRE tires.

    A LRE tire with a max psi rating of 44 psi is bogus. What is the max payload of this supposedly E rated tire?

    I dont have experience with truck tires specifically but Ive learned to somewhat ignore the door rating over the years. Seems most manufacturers choose that more for ride comfort and road noise. Even on my sedans I always end up running quite a bit more pressure for better grip and MPG.
