Hello, This is my first post since buying my first audi so sorry if the question is stupid. Just before xmas I got my A3 sportback 1.8T SLine. I got it with the 18" rims option but found that there was much rubbing of the tyres on the inside of the bodywork. Of course I took the car back and Audi said they fitted rims with the wrong offset. Fair enough, mistakes happen. So today I collected my car again with the 18" rims with the correct offset but I notice that the tyres do not match what the Audi spec brouchre says. The booklet says that they should be 225/40 tyres for the 18" rims but Audi have fitted 235/40 tyres... Should I be concerned about this difference? Ta!!
