I was washing the S3 today and noticed the front tyres are scrubbed out on the inside edge. I was reading that camber can cause this, without knowing how much camber a S3 runs vs a standard A3, I was wondering is it normal?? or does it look like it needs a wheel alignment There is only about 3mm from the bump to the top of the wheel, so I'm guessing it's time for new tyres anyway. Is it something I could have done to prevent it? the tyres are the original potenza RE0504 with 21,000 km on them. Foy replacements I was thinking of getting continental sport contact 5 or Goodyear Eagle F1 Asymmetric 2, What do you guys recommend? Cheers Dean.
