Just swapped my Monzas today (front to back). My God that was hard work - they are so heavy!

I'll ask/pay my dealer next time.
(I know some say to keep the tyres with most tread at the rear but that will never make sense to me on a FWD car when I don't drive like a nutter much of the time. I find front traction and braking more important than worrying about the rear swinging out).
Anyway, while the wheels were off I gave them all a good clean inside and it just got me thinking what a brilliant design they are. Quite easy to clean with a wheel brush and a sponge while they're on the car and they still look so good. Some of the straight spoked wheels can be an absolute pain to clean.
