Tire and wheel fitment

[BB c7]

Hi guys. Question on wheel and tire fitment.
I was wondering if can run et38 20x9 in the front and et45 20x10.5 in the rear. Running 275/35/20 tires on all 4 corner. Can i do that ?
Would it be considered staggered or square set up ? Is my Quattro okay with this set up ?

What car? S6 from your photo? Yes, that is a "square" set up (all 4 tires the same size = square).
That tire would be a little squashed on a 9" front rim though.

Thanks for replying. It is a a6 c7 with sport suspension. So i guess I shouldn't have problem with my Quattro system right ? What if i go with 275/30/20 tires ?

No, shouldn't have any issues with the quattro system. I'd rec the 275/35's though (for both ride comfort and fit on that front rim. the 30 series would be even tighter)

Rolling diameter should be within 2-3% percent. Do the math. There is a difference in rolling diameter if using the setup you describe.

OEM C7 A6 comes with 255/35R20. You want to run 275/35R20.


265/35R20 would sit a lot more closer to OEM fitment.

Best option is to go with a 265/35/20 tire on a 20x9" wheel with 35mm offset. Or do a 265/35/20 tire on a 9.5" wheel with a 38-40mm offset. This will give you an absolutely perfect fitment. Do all four corners the same.

Thanks for responding. Yes i heard before that best option would be 265 tires with 20x9.5 wheels. But there is not many wheels that has 9.5". Specially in my price range. I am trying to achieve most concave look possible. I like a niche wheels but they don't do 9.5" wheels. It is 9" or 10". Unfortunately 20x10 won't work on c7 a6 i guess.
