Just looking to see what everyone runs their tires on? I usually run them on the recommended psi that is on the tire or more but i got an oil change and they said my tires were low and so they put i don't even know how much into them and i should have asked because it feels like a whole different car the ride is great. so what is the "best" psi for tires for regular road use?

 

i just checked all my tires today cause my car was pulling to the right. my right tire was at 20 psi. the driver front was at 40 psi. the only two that were ok were my two rear at 30 psi.

after that my car became back to normal

 

I found that slightly over-inflated (i.e. 40-42 PSI depending on the tire) run better overall.

 

on the road, i run 35 all around.
today on the track, i dropped it to 30 and it rose to 38 psi.
running falken rt-615s btw.

 

jus do what the sticker on the door recomends ,you will be best off

 

When tire pressure is quoted it is always specified at room temperature (cold) when you are running track (such as Auto-X) over-inflated tires will provide you with a harder sidewall, thus eliminating sidewall flex, and making your turns more precise

 

For daily driving, I run 35 psi in the front and 32 in the rear. For autocrossing, around 38 front and 35 rear, then I play with it as the tires warm up and I get a feel for how the car is handling.

 

well yea..for the first few hot laps, i left it at 35..then it rose to 40something...falken says the tires shouldnt be at such a high psi, so i dropped it and rode 38 around for the rest of the day..

 

The stiker recommand 32 psi put I run on 35 in front and 32 in rear. I drop presure in winter for better grip.

 

Federals up front, 40 PSI both
Falken Ziex in back at 35PSI..

At the track 20 up front and 40 in back.

 

I run 37 all around and when its warmed up its at about 45psi

 

does that go for aftermarket rims with different tires too?

 

nah different tires n different sidewalls are different.. but if u just maintain a 35psi all around you should be fine.. track stuff is something else...

 

i find that more pressure in the front seem to handle better

 

How did I not post in this thread originally?

36PSI on stock size, DD tires.

For the "race tires" (215/40/17).....depends on the course surface and amount of grip/rollover. Last event I ran 32 PSI in the rear and 35 in the front I believe (slick surface). Actually the fronts were different due to a heavy right handed biased course. I think my left front was at 37, while the right was at 35.

With a grippy surface or heavy load on one corner I will raise the pressure a bit to compensate for rollover.
