Sorry bout not getting back been a bad couple of days! Anyway, I bought these tires from 4wheelparts.com along with 4 rims (ar-40?) for about a grand back in '99. I run them with 22-24 psi and my guess would be arond 30-35000 miles (mostly road English 4x4 parks aren't that great) The reason for the "oval" call came from a buddy of mine who is an advid 4x4 guru (although in a jeep) and noticed that when i was driving the left rear well would "bounce" or roll like an egg from tip to tip so this weekend i am going to remove it and see what i can find. I will let you know whats up with it after then.
