Hey mate,

You will need to spec the 18" alloys that you are looking at/have as they are different widths.

The correct size tyre for an A3 on 18" wheels is 225/40 R18 and the width of OEM 18" wheels is 7.5J. If your buying after market wheels then they will be probably 8J width but 225/40 R18 tyres will still fit or you may want to fit 235/40 R18 as fitted to the A4 or TT.
