take a bb gun to em. the birds not the tires 
for the tires, the higher the psi, the more ur wheels are prtected from potholes and such
yeah BB GUN em down! Just remember, the higher the PSI the less traction you'll get...BUT you will gain gas mileage with higher inflation. I would reccomend around 30 on the street and 25 @ the track. I had the 712's on my 17's in a 205/40/17 and i kept them around 30/32 for daily driving, felt great and gripped well. Just be careful on those tires in the rain when you are turning, they kind of suck in that situation.
