Base Wheels for the Track, Tire Size?
 

What size tire is ideal if i want to do a track day? (without rubbing of course)

2011 370z on Stock Suspension
- No Spacers

Front:
- Wheel: 18x8
- Tire: _______

Rear:
- Wheel: 18x9
- Tire: _______

p.s. I've decided on these wheels so no square-setup suggestions pls.

10% over, under 20%.

Can anyone translate this for me? :ughdance:

Lol.

8" / 0.0393 = 203.56. 203.56 x 0.1= 20.36. 203.56 + 20.36 = 223.92. = a 225 tire.

203.56 x 0.2 = 40.71. 203.56 + 40.71 = 244.27. = a 245 tire.

9" / 0.0393 = 229. 229 x 0.1 = 29.9. 229 + 29.9 = 258.9. = a 255 tire.

229 x 0.2 = 45.8. 229 + 45.8 = 274.8. = a 275 tire.

Front, 225-245

Rear, 255-275

Squares best so maybe 245/255.

265 for the rear sounds better.

If you want to go bigger on the fronts you have to use atleast a 10mm spacer. Since the tire would bulge a little it would end up rubbing on the upper control arm when turning. I ran into this problem when I was getting new tires this past November. So I just stuck with stock size and I am getting track only wheels/tires. Turn your wheel all the way and get out to look at the clearance on the inside. Stock is barley a finger width.
