I bought new a Toyota Hilux pickup with factory Bridgestone LT tires. They came with 45 psi on all tires from the dealer, and that's what I have kept them at since. I load only light to medium loads at the back and only on occasion. I have yet to rotate the tires, which are only at 7000 mile mark. The rear tires are fine, with nice equal wear, but BOTH fronts now show some heel/toe wear throughout the whole circumference. The affected tread blocks are the row just inside of the middle of the tire tread. The inner and outer shoulders are OK. The wear is obvious and affects the trailing edge of each tread block.
I am going to cross rotate the 4 tires this weekend front to back and will have to check the front suspension factory alignment later. If the alignment is not correct, then obviously I will have to adjust 'em and go with factory specs. But if the alignment turns out to be good and at factory specs, I'm inclined to change the toe, in an effort to improve the wear situation. Should I go to slightly more toe in or toe out?
Finally, should I also experiment with front tire pressure? I'm at 45 psi, and the manual says inflate the fronts to 42 psi.
