What is the factory recommended tire pressure on the 205/55 R16 factory rims and tires? My stock size was 195/65 R15 and was to be at 30 PSI cold.. Just got a set of 2000-2002 Z24 rims for my 2001 Cavalier and got new tires on. I don't want to run them with the wrong pressure, so figured I'd ask. Of course my door sticker only tells me the PSI for my 15" wheels, and the owner's manual only tells me to read the door sticker (Super helpful!). I was hoping it would have a chart for the 3 wheel sizes Cavaliers came with. Online searches have come up with nothing. Hoping a Z owner can help me out.

I have to admit I LOVE the way the car looks with these rims on it.. Makes me wonder how I went a year without them! Check out my profile for before and after pics if you are interested.

Thanks!

30-35 psi is what i run mine at , usually closer to 35

Factory rating was I think 28. I never ran that in mine, I always ran about 32. 28 is very comfortable ride wise, but very sloppy.

I run mine at 35 psi. Anything between 30-36 or so will work.

it should say on the sidewall of the tire but if it helps i run about 34

dear lord dont listen to that logic! that pressure marked on the side is the MAXIMUM pressure the tire can handle, not what is ment for your car.

*disclaimer* - i am an expierienced tire installer, but this is my own personal opinion. please, do not attempt to increase your vehicles pressure untill you have a grasp of what you are doing. i can not be held acountable for your safety.

off of the top of my head, it works out to about 30 or 31 psi (going by memory of my pressure tables). i do run mine over the factory settings for 2 reasons.

first, running your pressures a little bit higher will improve handling. it will get rid of your understeer. cars are designed to understeer because, well, people suck. the average person cant drive for beans! if the car were to go into oversteer, they wouldnt not be able to control it.

the second thing is for a bit more even wear. this also depends on the car and tire on that car. the cavaliers tend to wear the shoulders a little bit faster than the center of the tire when running them at the recomended pressure. so, when the pressure is increased a little bit, it generally evens out the wear.

like i said above, most people cannot handle and correct a vehicle once it has been placed in an oversteer condition. if increasing your pressure over the factory recomended pressure OR equivilant pressure able to carry the vehicle load capacity in plus sizing applications, increase the pressure the slowly and gradully until you are comfortable. do not increase the pressure any further if you are not comfortable.



Injection is nice but id rather be BLOWN!
