I boosted mine into the low 40's. I have 235/45-17's

As the tire get wider, pressure increases or you'll be bashing the rims.

Thats what you want at the track. My 18's are run at around 40psi. I think the tire says 44psi.

oh my bad,i really haven't seen what low pros have on the side , i was just assuming that all tires were around the same PSI.

Your a complete idiot if you dont know how much pressure to put in your tires, and it almost always says on the side of the tire

My tires say 44psi max on the stock tires, I put them up to 42, then tire kingdom dropped them to low 30's :wtf:

should I put them back up to 40ish? better gas mileage?

well 40psi would cause the center to wear faster i would suggest to put in what the car tells u to but in it should b on the drivers door
