Good point Ken. I don't need any tyres right now and probably won't do fir a while so will think more about it when I do. I do know that the laws of physics dictate less pressure on the road the wider the tyre so wide tyres may result in more slipperiness .... Isn't it something like downward pressure ( onto the road) equals weight over area or something like that? (my gcse physics is very shaky) I just thought there might have been benefits but it's something to mull over. I agree though, being careful is the key to alloys staying unscratched!
