Tire Pressure for Non-OEM tires (05 tC)
 

should i use the same tire tire pressure recommended by toyota/scion for my 18 inch tires ? when i bought the car it came with 17 or 16. i just a tire mounted and the guy there said they just put 32 psi on all tires !!!!

you can still go w/ oem specs, thats what i did and no problems

OEM pressures is what you want to follow.

32 psi is good, no matter the size tire you got... :clap:

that's what you should do anyway.

32/29 front/rear

OF course, if you do autox it, I recommend 43 front, 39 rear. But, be sure to lower it back to spec after each event, or you will wear the tires badly and unevenly!

It is obvious that I am itching for autox to start back up this spring huh? :D

i kept my oem wheels at 35-37psi as well as my new wheels.

At the place where I get my tires rotated (America's Tire), they do 31psi f/r.

Regardless of what the tire places say, run 32 front/29 rear. The cars weight distribution is where those numbers come from and you will get optimal wear characteristics that way.

If you run a tad higher to get a tiny bit more mileage, I would go 35/32, but I wouldnt go much higher. I ran the first set of tires on mine at that for a long while, and it was ok, but you could start seeing that it wore in the middle slightly more than the edges.

And of course, rotate at every oil change.

Been running my stock Yokos at 36F / 32R since new. Now after 2 yrs and 10k miles, wear is fairly even, actually a bit worn on the edges, more than in the center, since I"m fairly aggressive with corners/turns. Better mileage & performance than the stock reco pressure from scion/toyota, so I'm sticking with it, and have been doing the same on all my cars for over 30years.

i run 28 in the front and 32 in the rear, but i have a traction problem. but if your just cruzin then eom tire pressure is fine.

.. it's supposed to be 32 front... 29 rear

higher psi in front... :question:
