Rich..nice to see I am not the only one with the eternal optimism of the BMW driver
I hadn't really thought about the runflat issue. I have only ever driven cars on the size wheels and tyres it came with, so this is a bit new to me. If I am running the 275/35 on the rear and 245/40 on the front on 20's, is there some clever calculation that will tell me what size tyres I will need to run on 18" rims?
I am very tempted to buy a set. It will probably guarantee a fine and dry winter in the UK
