Hi, I have just acquired some 15" 6.5J Audi A1 wheels currently with 205/55R15 tyres on. 3 of these tyres will need replacing and I was wondering if I am best to stick with this size tyre or whether it might be better to replace all for a more optimum size. Does anyone know if the 205/55R15 tyres cause any issues on the A2 on this size of wheel? Many thanks for your help.
