I was worried about that before I did some major driving.

So when my tires came in they had a sticker on the boxes saying they were filled to 44psi and should be adjusted to obtain good tread wear. The max on the tires is 50psi. What do I set them at??

I'm currently running 255/35/20 in the front at 36 psi and 275/35/20 in the rear at 34 psi and I like the ride quality at these pressures. My tire shop recommended I run them at 40 psi , but that's to harsh a ride for me. You want to make sure you don't go too low , I was running a previous set of KDW2's at 32 psi in the front and 30 psi in the rear and that was too low. The tire wear and the ride were perfect , they had 18K miles on them and still looked new. However because the pressure was too low , the tread started to separate with hair line cracks on the edge, so make sure you don't go too low. I read somewhere one time that a rule of thumb was 2 psi above OEM pressure for every inch increase in wheel diameter ...
