Audi S8 wheel/tire diameter change
Hi,
This is similar to other threads about the S4 21" wheels not being ideal for tire selection, but I found a 255/40/21 winter tire that just came out (Pirelli Scorpion Winter). The only issue is that increases the overall diameter by 2.5%. Is this an issue for all of the mechanical/safety mechanisms on the car? I have read that 2-3% is acceptable for most cars but wasn't sure about this one with all of its advanced features.
There are some 275/35/21 winter tires coming out that would fit much better but won't be produced for another 3-6 months.
And of course, another option would be to get 20" rims but a lot of suppliers are saying that their rims may not clear the calipers.
Thanks!

We do have some 20" and even a few 19" wheels that will clear the brakes on this car.
You can view them in the "winter" section of our site here :

OE 20's will clear calipers. Aftermarkets too diameter wise but not necessarily side wise.
