Just to make everyone aware of an issue to watch out for.
I recently had the rear tyres replaced. Several days later I was washing the car and noticed a couple of silver areas showing on the edge of the wheel. On closer inspection it became obvious that some mechanical force had pressed the powdercoat finsh away from the edge leaving a blob of powdercoat, and exposed alloy. The dealer says that the wheel will be replaced under warrantee as it was changed by them. According to the dealer the powdercoat is very delicate and they have seen this problem before. I have now had three tyres changed and this is the first one I have had this problem with. The lesson learned is to always check the wheels for damage following a change.
