Problem is with mine, when a TPS gets to 36 PSI, my dash becomes lite up with a low tire pressure warning. I got 15K out of a set of PR2's running 42 psi. I live in the North Cascades so twisty roads are common place. I never had a tire slip out except when there were tar snakes in Utah in the middle of summer.
@Conrad, your right 42, sorry, @Tim, my low pressure comes on at 31, so did my 08.
On my pressures, I manage about 7-8 K on the front and MAX 3500 miles on the rear, told you I ride it like a 1400, Roads here in Louisiana blow, so many straights, now my ZRX 1200, I can easily get 10K out of both tires, because I baby it.
Plus I got too much money it to throw it around and smash it....
