tire pressure
For 2003 G35 Sedan with Sports Sepspension it is 215/55/R17.
Whatever size you want.
P215/55R17
I had a similar problem on my 2006 G35. All I had to do was check the tire pressure on all wheels and fill them back up to spec; the light went off by itself.
Too early to predict.
Fill tires to 30 pds.
215/50/17
Changing brake pads is a simple task to maintain the car. Lift the car, remove the tire, brake shoe and the old brake pad, put in the new brake pad, replace the brake shoe, tire and lower the car.

Inflating a tire with air is a physical change because it is not changing the tire chemically. It is only changing the physical appearance of the tire.
