Hello all, what are the widest tires (dimension wise) that could fit on S5 tires. I just ordered OEM sized snow tires today and just thought of this when I swap them out for summer tires. Thank you.

Are you asking what is the widest tire that can go on the factory 19 x 8.5" wheels?

Yes stock OEM wheels, sorry I didn't specify that better. Should have said, "What are the widest tires that could fit on stock S5 wheels".

According to TireRack.com, it looks like anything wider (and therefore lower-profile) than 255/35 would require at least a 9" rim:
