first i'am just new in here and my question is i have volk racing G-tc rims 20' front tires 245/35/20 and rear 275/30/20 what PSI should be?

 

Welcome.

Start with the recommended pressure. Watch for uneven tire wear. Adjust accordingly.

 

what is your suggestion for psi?

 

Same as the OEM tire. 35 PSI.

 

i run 33 all the way around, 295/35/20

 

What do the sidewalls on the tires say for inflation pressure in PSI????

 

is this question directed at me?

 

What is marked on the sidewall of a tire is maximum pressure, not a recommended cold pressure. Never inflate a tire to what it says on the sidewall.

davidv is someone whom you should trust.

 

50 maximum psi press said on the tires nitto nt555

 

oh, and iirc 35psi is cold pressure, as in not driven on in the past few hours.

 

Best way to find out is call the company that makes your tires and ask them recommended psi for your size tire. It all depends on the footprint of your tire, meaning amount of tire contacting the ground at any given time. You cannot go by stock tire sizes because it is completely different size.

 

thanks

 

295/35/20?

That size doesn't fit our car. The correct size for the rear would be 295/25/20.

275/35/20 = rear, sorry.

 

The tire pressure number you see on the sidewall is its maximum pressure used to determine the tire’s overall diameter at full inflation, and has nothing to do with the pressure you use on your Z.

Regardless of the tire brand (and its maximum pressure value), you inflate your tires to the psi that Nissan recommends for the Z.

Davidv posts the correct information here. Inflate your Z tires to 35 psi.

+1. The man knows his stuff.

 

I know my Vredesteins say the max is 51 psi but mine arent that high. I also cant remember but I think my stock tires on my 03 had a max of 51 but neither is actually inflated that high. But if both have the same max you should have an idea of the ride on both. Remember one thing though with the 20" tires you have a smaller sidewall so you might wanna run a lil more pressure.

 

+1. Look on the inside of your door panel where it contains the manufacturer's information. It should tell you the psi you should be running at. It's 35 psi.
