Dear tri--  I was about to tell you to look in your owner's manual, until I looked in the owner's manual and they do not tell you.  Instead they tell you to look at the tire placard which is affixed to the inside of your console box lid.  They also remind you that your car does have a low pressure sensor and the car will tell you when you are low.  If you ever need to look at the owner's manual and have lost yours, go to--  http://www.courtesyparts.com/nissan-manual/pdf/2003-Nissan-350Z.pdf.  You will find it there.   Good luck from Bovan.

hey genius....it says on the tires.....and u can also look at the sticker put on the door well on the driver side.

hey genius...it does NOT say on the tires, thats the maximum pressure the tire can handle, has nothing to do with what you should be setting tire pressure at.

There is however on a sticker attached to the door pillar...

i use 34psi in the front and 37 in the rear, works well, helps generate a little bit of turn in oversteer.

hey genius...isn't that what i just said????  and tire pressure should be how you want it, they can be softer or harder.....and u use hte mx pressure as a guide line....

lol nice

you see what mark does, he uses custom tire pressures...maybe u shouldn't try and correct someone next time.
