cheers for the info guy's
as for different sizes, I know its fine, just have to remember to tell the garage to check when they take wheels off.
(after removing my wheels to do brake lines front+rear, the wheels have gone back in a different order, same sized tyres all round so doesnt really matter)
what i used to fo with FWD cars is once the front set are half worn, I move them to the back and put new tyres on the front, dont know about RWD though as the drive wheels arent steering.
as for Falkens, I wil have a look, dont really want fast wearing tyres, I do mostly rural milage on terrible roads!
