What should be the correct tire pressure?

fuapiti · 10-29-2007, 05:29 PM

Ok, so I got some SSR wheels and some Potenza RE01R tires from the TireRack (Awesome service), the set came with 35-40 psi already in, I know this is way to much but I dont know what the correct psi level (F&R) should be (for daily use). I thought maybe the recommended psi levels for the stock 07 STi wheel/tire combo should work since my set is the same size, but I'm not sure since the tires are different.

If anybody knows please let me know, I'll appreciate it!

If it helps the wheels are 17x8 and the tires are 225.45.R17...

Thanks guys!

start with 33 in the front and 32 in the back and feel free to play around with it. Anything between 30 and 35 will not hurt anything.

try 35 that way u could save some gas mileage too.

what ever you do run slightly more in the rears b/c our cars love to squat under heavy accleration, not to mention thats what its suppose to be any ways, run like 32-35 front 34-37 rear

^ no that's incorrect. It's recommended to run more pressure front than the rear - this is due to the weight distribution f/r and keeping tire heights close to even for the benefit of the diffs- right in the owners manual

I'm running RE01R's as well- daily driving 35/33, for autox 37-40/33-36 dependent on surface/conditions.

Yeah I thought that was kinda off, 35/33 makes much more sense...

Thanks anyways guys!

Then why do you allude to the fact that you know the recommended psi levels for the STI tires here?

Big Sky · 10-31-2007, 07:27 PM

from the 04 FSM the STi is 33/32 don't know on the 05+'s

Nose Nuggets · 10-31-2007, 07:47 PM

who cares what the stock pressure is. your tire pressure should be based off the max PSI of the tire you have.

No man, I'm asking the recommended psi combination for a wheel/tire combo that is the same size as the OEM STi one (07 at least). I mentioned it just in case somebody here owns an STi and could give that info to me.

Sorry for the confusion!
