I have a 2005 G35 coupe with sport suspension. Rear wheels are the 19 inch that come with the car. I took it in for the 30k mile maintenance, and the mechanic told me my rear tires are bald. These are the original tires, so I guess I got my money's worth out of them. Front tires are still ok (7/32nd inch tread).

1. How can I find out what kind of tires I have? I want to shop around to see what the best price is. Infiniti said $380 per tire.

2. If I want to upgrade, what should I look at? I'm pretty happy with the way the car runs now, so unless there's some real benefit, I'd probably be happy with getting the same tires.

Thanks for all the great help you guys provide.

 

just read the brand & size tire right off the sidewall. All the info you need is right there. check out tirerack.com to compare prices. dealers are always going to be more expensive.
by the way, I would stick with the same tires. why run mis-matched tires. (meaning the rears are going to be a different brand than the fronts)
I cant believe you got 30k miles out of the rear. Im assuming your not a spirited/ occasional aggressive driver huh.
