Claireysmurf said:Silly question...but why does the rear have a different (lower) profile to the front tyres? Will they rub if the the car has 225/40/18s all round? 40s look a fair bit cheaper than 18s
Because they are wider. 255 on the rear and 225 on the front.
The rear wheels are also wider so you really need 255 unless you want that horrible euro look.
