For what it is worth, here is my experiance with the wife's ride.
99 Trailblazer - Factory tires - Goodyear wrangler a/t's I think
Max pressure was listed at 44 psi, I ran 40, everyone told me
that it was to much, pulled them off at 95,000 miles and still
had a ways to go on the thread indicaters, replaced with set
of Michelan cross terrain suv's, Max pressure is listed 36 psi,
running 30, and I hope they outlast the darn blazer. My $.02
P.S. - at 118,000 miles now & brakes are OE & still look new.
