While we're talking about tire fitment, let me ask if anyone has done this on an A6Q: 215/55 16 Wheel width: 7.5 offset: 34 Stock is 195/65 15, offset 45. The mailorder places say 205/55 16 offset 34 will work, but I suspect they haven't tried 215/55, being a less common size. I'd like a little more sidewall than the 205 offers. TIA, Richard
