Hey,

When replacing tyres on an AWD car(MY03 WRX), do ALL FOUR have to be replaced or just 2?(For example, right rear is stuffed so u change both sides of the rear).

The reason i ask is because maximum motorsport advised me to change all for to keep all wheel diameters the same and therefore no diff problems, but city subaru told me i would only have to change the one thats stuffed, plus the opposite tyre. Im pritty much in need of a new tyre(running on the steel wires) but unsure how many i have to be replaced.

What maximum motorsports told makes sense and is probally the safest way to go, but what subaru told me is a cheaper way .. so i hope its true(but i dont trust advise from any subaru dealership)

Help will be much appreciated.
