How much tire pressure?
How much tire pressure should I be running for the front and back. I have the 17/18" set up. Will I have to reprogram the tire sensors once I get the right amount of tire pressure in the tires? My car is a 2000 C5 if that helps. Thanks!

For instance, before I drove up to PA I inflated my tires to 29 psi COLD in near freezing temperatures. That night, on the way up, the tires eventually rose to about 31-32 psi. The next day, warmer temps set in at about 55 degrees. Suddenly my WARM temp tires after driving were up at 34-35 psi range. Hope this helps.

I keep the tire pressure at 32PSI (cold) year round' and the ride, handling and longevity (40K on previous set) of this make of tires has been great.
Good luck...

I'm certainly no tire expert, but wouldn't "switching" from a run flat tire with steel sidewalls, to a non runflat tire, without the steel sidewalls, creates a totally different situation with regards to tire pressures??
It's kinda like comparing apples to oranges... Even thought they're BOTH tires, they're certainly different in construction, which might necessitate a difference in tire pressures??

I think the reason the GY EMT recommended tire pressure is 30 PSI (cold) has to do the presence of thick steel sidewalls in it's construction.
30PSI (cold) in my non-funflat tires, has resulted in a lot of "sidewall flex", because there are no steel sidewalls helping out. This made for a lousy handling car and uneven wear on the outside edges of the tires....due to underinflation.
Based upon my experience, I would recommend 32PSI (cold) as your non-runflat tire pressure...year round.
Good luck.....

If your sensors are already programmed to the car, then no need to do anything just because you add air. The sensor will pick up the change once you drive the car.
