I recently picked up a set of 19 x 8.5 x 255 audi a5 wheels. I curently have 18 x 8.5 x 235 on my 2003 Audi a6. I put the new set on and there is rubbing in the front, I understand the offset is off by 3-5mm? Even then with a spacer it looks like it wont clear the fenders. Anyone have experience or should I trade these up. Maybe 2,000k miles on the tires. Thanks!
