Thanks

Here is a link to a site with the OEM tires for your VEHICLE:

20X9 rims are the usual but these tires will fit 9.0 to 11.0

Hope this helps

275/35x20 is the size. What is the offset (ET) of those rims?

Denislav39

The tires on wheels then I have now are
255/35/20 front
275/35/20 rear
I think to change only front

stagger tires on an AWD car ? If you are wanting to change two tires, change the rears to the same size as the fronts.

That wouldn't be good. Too small outside diameter and too wide rear rims for 255 tires. 275/35x20 are the right size. What Op have right now is unacceptable on Quattro because of quite different outside diameters and not good for handling on a nose heavy car.

Misha has it right, especially w/ the 10.5" rears. 275/35 makes it stock D3 A8--W12's or later 4.2's w/ optional 20's

What's happening if I use this tires now ?
And the better way will be to put 275/35/20 on the front or 245/45/20 ?
Thank you guys

honestly, if you want staggered, for performance reasons the big ones should go on the front! No lie. (ignoring the clearance issues Misha was correctly on to) Of course then your car will look hideous and we can all laugh and point. But for those of us who know Audi's, we laugh at staggered the "normal" way too. Except on an R8, it doesn't go w/ Audi's. Period.

More generally answering your question, you need in any case to get to diameters (running circumference actually, but diameter suffices) that are within a couple of percent of each other for quattro reasons. The 275/35s are typically 27.7" Given your varying wheel widths, you may kind to "need" to end up there to have a width that is spec'ed for both your narrower and wider wheels. The normal way to do that of course is to use the same tire and size on all four wheels. After that if you want to performance subtract it with staggered but still maintain matching diameters so Audiphiles laugh, have at it.

You are making it more and more complicated. Also didn't answer what offset are those rims you have. If you want valuable answer you have to provide necessary input.

10.5" rims most likely has to go to the rear. 275 tire is minimum width for that rim. So 275/35x20 you have are good.

Since staggered setup is not good for A8 (as MP explained) you should go with 275/35x20 at front too.
