If you have to replace tyres all round it can get expensive, I'm thinking of replacing my rears which are currently 215/45/17 with what I understand to be the correct rear size of 225/45/17 but want to get my wheels powder coated first.
Unfortunately my rear self leveling headlight sensor packed up recently so that was just over £400 fitted at Lexus Bristol, so my plans have been set back somewhat, plus I need to sort out an annoying knocking noise which both Lexus and my mechanic friend can't get to the bottom of.
Frustrating, but such is life!
