Tyre Sizes

[newbo]

At the moment I have 235/60/15's and I have just bought some 17 inch rims and I wonder if anyone can tell me which is the most suitable size of tyre so the aspect ratio is still compatable with the car. 55 50 or 45??

Has anyone tried any of these and what were the results, I would appreciate any help at all because I would like to get the right tyres the first time if possible!

Thanks in advance
Steve Newbury

PS Anyone going to Le Mans this year?

Hi Steve,

As to being sure they won't rub anywhere or to which make/rating etc is best I will let others offer suggestions.
