30 psi cold all around. It is very smooth with that pressure.

Re: What's your tire pressure? (CarolinaC5)
after the tires are heated up .. after five minutes of driving I check to see that they are at 30 psi... That is a Hot reading ..... this number fluctuates because of road surface temps... Black top in the summer can get to 160 degrees... it will effect your tire presser..so I adjust the temp.. on a season level.. 25/25 psi cold in the summer.. 29/30 in the colder months.. to achieve a 30 psi at run temps.. I have 37000 miles on my original run flats.. 3/32 in the back/ 4/32 in the front.. Ill get 40,000 miles out of these tire.. and they are even all the way across.. the center tread is 3/32 the outside tread is 3/32

Re: What's your tire pressure? (CarolinaC5)
Ever notice the pressure recommendations are different on the tires versus the sticker in the door jam (forgive my ignorance, as I know there is a technical name for this sticker).
I THINK the tires say 37, which is what I filled them to after getting it out of winter storage last spring. My DIC started going nuts:
LF HIGH PRESSURE *blink, blink, blink* RR HIGH PRESSURE *blink, etc.*
30 is what I keep 'em at.

The pressure listed on the tires is the Maximum pressure you can run them at. The sticker on the Driver's Door is what you should go by.

Re: What's your tire pressure? (CarolinaC5)
I ran my RunCraps at 32psi (cold) and got 35,000+ miles on them (with some tread left over!).
I just put on a set of Michelin Pilot Sports and I'm still set at 32psi.
:cool:

They should be 30 psi all around COLD (not driven). That reading on the tire wall is usually the maximum psi cold...
Note: moving your car raises the pressure quickly. I believe the sensors don't read correctly until 11-15 mph. So as soon as you pull away check before they get hot, and when you get to an air pump-guestimate how many pounds they need-and then drive around like an idiot :conehead trying to adjust them to within 1 psi of each other...
Note, the 18's out back tend to run 1 psi hotter than the ones up front-and every ten degrees of ambient temps raise/lower the psi by about 1 psi.
Even if the car is parked, and the sun is hitting one side and the other is shaded for a while-expect a slight difference in temps.

Re: What's your tire pressure? (Evil-Twin)
why would you want to check them before they get too hot??? they see that hot temp... for your whole driving experience.. the reason most ppl wear out their tires is that at 30 psi cold.. they get to 36/37 hot.. whicj raises the center and causes pre mature wear... HOT is were you want to get your rreading from.. cold is were the car is not moving.. the tires never wear out when they are cold.. cause the car isnt moving.. and ambient means nothing .. what does mean something is the road temperature.. black top can get to 160 degrees F. on a 95+ day with a lot of traffic.. same conditions on a cement road.. is 30 to 40 degrees colder .... check your tires when they are hot.. keep them at 30 psi...
Just keep this in mind and be careful with tire pressures.

Re: What's your tire pressure? (Evil-Twin)
Dude, flat out...tires are to be checked cold, just like you don't check your car's oil right after you've driven it...
Inconsistencies abound in vehicles. The only thing that really is an acurrate measurment is when it is "cold." Certain racing tires perform better at certain psi's and heat ranges, but these are race tires...Goodyear's are to be kept at, and run at 30 psi, COLD (though some my find advantage ot over/under inflation for the track-depending). There performance, tread, wear rating is based upon when they warm up to 32-37 psi-based upon driving and environmental conditions.
