Well, maybe some lower profile ones, not too bothered

If you go for a lower profile (say 45) with the same width, the speedo will read 3.5% too fast. Go lower to a 40 profile tyre and the speedo will be 7% out. Not really an issue I guess but you will be going slower than you think!

Then you need to consider how it looks with 15" wheels and small tyres.... bloody silly I think! :think:
