19" Tire Pressure Question
 

Hey guys,
Really simple question. I just wanna make sure I don't under inflate the tire. But can anyone tell me the correct psi to have the tire set at for 19" rims? I have all 4 set at 37 psi right now (what manual says for the 18" stocks).

Tires are 245/35 & 275/35

Tire pressure will not vary by tire size, it goes by vehicle weight. What the manual says for stock 18's, holds true for aftermarket 19's. I personally run 36psi all the way around on my 19's.....

ah gotcha. I didn't know that. Learn something new everyday.

thanks!

19 inch tires are bigger than 18 inch tires so you have to add one more inch of air pressure.:)

Ha...Ha... :icon18:

I did get the joke, but others might take this seriously and have a misunderstanding.

Just so that it is clear, tire pressures remain the same, independent of the wheel size. 35-37 psi is a good starting point no matter what wheel size or tire size you have on your 350z car.

Hey guys, thanks for the info on tire pressure. I do have a question for you though.. I have z-rated tires on 20'' wheels and was wondering what the correct PSI should be... also please state if it's the correct psi you're listing is when the tires are cold or hot. Thanks!!!

No matter what the tire size, the PSI is the same depending on what your car should be. Stock PSI can be found on the sticker inside the driver door sill or in the manual.

vo7848 already gave an excellent answer.

This really was a great answer thank you. My Z. just to keep this thread fresh
