Will this tire/wheel combination work?

OK...Here is my plan of action:

Fronts: 20x8.5 wheels with 32mm offset and 275/40-20 tires

Rears: 20x10 wheels with 34mm offset and 315/35-20 tires

With this combination, can anybody tell me if I would have any rubbing or clearance issues?

(car is not lowered and the tires would be Michelin Pilots on the rears and Pirelli P-Zeros on the fronts).

I know that the wheels are slightly undersized by 1/2" for the size tires I want on them, but I want a little bulge look to them.

Thanks in advance!

The rims will stick outwards a little more.

Here's a good tool: http://www.1010tires.com/Tools/Wheel-Offset-Calculator

Stock, 20x8, et35/ 20x9, et40

With your proposed setup:
Fronts: 3mm less inner clearance, extends 9mm more outward
Rears: "" 7mm, "" 19mm

Good luck! Padre

Thanks Padre!

Do you think I will have any problems with the 275's rubbing in the front inside wheel well at full turning? The height of the tire on the proposed setup is the exact same height as my stock setup, and it looks like I have plenty of clearance between the top of the tire and the bottom of the quarter panel (1.75" in the front and 2.25" in the rear). So, if the tire sticks out a little beyond the quarter panel, is that anything to worry about?

Thanks.

On my street setup, I have 20x9's with 275's on all corners and they are fine.

You'll be another 1/3" outwards on the front, so you SHOULD be OK.

Your rears will be even further out, so I don't know. But if they stick out, you'll be OK, it'll just look not as great.

Get out your tape measure!
