You're both wrong & serb is correct... best tyres should always go on the axle which is delivering power. So... FWD cars... best tyres on front... RWD, best tyres on back. Obviously AWD vehicles are a bit more complicated because it depends exactly how the power is balanced between front and rear... but if it's 50/50 then I would put them on the front due to the steering. ... that's for safety anyway I like drifting... so it's good tyres on the front and crap tyres on the back in a RWD car
