However, depending on if you got the sport package, the tires may be rated for 45PSI for normal driving (tread ware). Most vehicle manuals will say 35PSI to be on the safe side (as most tires are rated at 35PSI), but newer tires these days are rated much higher for daily use. For track days, it's good to air them down to about 30PSI. They're perfectly safe (and definitely going to have more life) at 45PSI if you're not tracking the car.

sports package tires here and the tires clearly say DO NOT EXCEDE 40 PSI. i hate to say it but i am going to listen to it.
front tires 37.5, rear 38 and 39. There all set to 35.5 now, it gets cold here lately so tonight they will be at 35, will put them at 35 even in summer time.
