I have an 06 350Z GT. GT rims 19" in back 18" front. They have the factory shipped Bridgestone R50A Potenzas front and back. Does anyone know what the ideal tire pressure (72 degree day) settings are? Thanks in advance.

 

Owners manual is your bestfriend.

you can also look at the tire loading information in the sill of the drivers door.

I run 35 in mine, but i believe 32 is recommended?

 

also remember to fill/ check your tires when the tire pressure inside is the same as outdoor air temp. in otherwords. let your car sit for at least 4 hours after driving and allow your internal air temp in the tires to return to whats known as "cold" pressure.
