hi, i was wondering what psi i should put my stock RS-As at? i guess id like to add that im more of an agressive driver so im a lil more sided to performance than comfort u might say. also everything is stock, rims and tires.

The inside of your driver's side door will tell you the proper psi for your stock tires. Anything different could cause undue wear on your tread and decrease gas mileage.

I believe it's 30 PSI all around.

Make it a minimum of 30 psi on COLD tires.

I just set my tires today at 34 psi front & 32 psi rear at 11C/52F on cold tires.

hmmmm, i just did mine to 35 front and 30 rear. ive heard u should go to the max
(44) i dont know tho

NO!! Don't EVER set the tires at max pressure COLD. ****, don't even set them at 40 cold.
I've found the best pressure is right around 32/34.
Any more and you risk blowing a tire on hard bumps.

Also, I said 30 cause that's the door sticker says.
I keep mine at 34 front and 32 rear Hot. That works for me. Of course, when I have V rated tires on the car, it tends to cup them.
But, I don't care. 34 is a good all around pressure for my driving style.

Unless your driving a 1 ton 3500 dully truck, then you don't need to go to 40 psi.

thats wat i was thinking too, cuz air expands wen it gets warmer.......
so 35F and 30R is good?

Well, is that 35 front 30 rear cold pressure?

If so then I would lower the 35 to probably 34 or so, cause even though 1 PSI seems small, when your 35 psi tire gets hot, it will go up to about 37 maybe 38, and that's starting to push it.
If you set it at 34 cold, it's still a little high, and your tires will cup (if you don't know what cupping is I can send you a pic of my old nitto's that I had), but it's less of a risk of a blow out.

32 Cold is a good pressure in my opinion for pretty much all cars out there running on stock wheels and tires.

but max is 44, not the high 30s, i cant imagine it would go up by 10 psi, i live in wisconsin not arizona or somethin haha

or should i have them = 35 front, 35 rear instead of 35 front and 30 rear

I put 35 PSI all year

Cardude, If you want to keep the front at 35 psi, then I would up the rear to 32. just to even things out a bit.
If your really concerned about what tire pressure you should run at, call your local tire shop and ask.

WilliamGT, I don't know what state your in, but if you experience snow at all, that 35 in winter is a bit high. It' actually better to have a lower psi in winter. Better traction for snowy roads.
But if your in a place that never gets snow, then 35 works I guess.

I think it's more of a preference thing, but you have no idea how many people I've seen at the side of the road that have shredded their tire cause they put the pressure at the max. One good pot hole and it's all over.
Tires is one of my more passionate subjects. This is how I think about it.
You can have 500 whp, and torque out the door, but if your tires can't handle it, why bother?

i just got new stock tires and they put them at 34f and 32 rear but like he said he is not down here in arizona lol

^^ Lucky. No snow for you.

05-06-2007, 11:19 PM
so i should put the rears at 32? or should i just even it out and put the rears at 35to match the front? haha

05-07-2007, 01:53 PM
any other ideas?

05-07-2007, 02:07 PM
dude, i think anywhere between 30-35 and youll be fine. i do 32 all around.

05-07-2007, 02:23 PM
jeeze, how many more answers do you want? between 30 and 35 is fine, beyond that is preference.

05-07-2007, 04:42 PM
so if i put the fronts at 35, wat should i put the rears at?

Zomgz 19 posts later were still talking about tire psi.

how about 33? or you could just try different ones all together and see what you like best, then report back to us with your findings.
