I recentley bought some 18inch rs6 replica for my 96 a4 and was looking for suggestions for a tire size.I also bought some neuspeed sport springs which will be going in they have a 1.3 drop ,I am looking into 40 series but should I get 215s or 225s thanks CM

 

235/40 or 225/40 should be fine. Depends mainly on your rode conditions.

 

roads are kinda rough I had 40s on my benz they were fine
