What tire pressure do you guys recommend im on 17" xxr rims with bridestone potenza re960 all season/performance tires im at 34 psi all around which is factory

 

Factory pressure is set dead cold so it'll go up like 5*when hot.
So account for that if you put in 34psi in the day.

 

So leave it the way it is?

 

i've found that 33f/30r rides the smoothest. i'm on 18s w/eibachs.

 

Factory.

For a 2k and 2k1 it is 33 in the front and 30 in the rear. I think 2k2 and 2k3 is the same, probably other model years.

Always go with factory regardless of tire size and type.

 

For my I35 on factory 17s, 32 PSI is the spec on all corners. I run 33 to account for temp fluctuations.

 

Well, I have a 2kSE with 17" wheels, and my previous tire was the RE960. I feel the optimal pressure is about 34-35, but I usually start them at 36. I check them when they feel soft, and discover the pressure is down to 32, so I pump them up to. And so it goes ...
