Hi All, after 51,000 Km

, yes thats 51,000, I'm sure my MINI service centre's going to tell me to replace my run flat tyres which I'm sure would get to 60,000 no problem.
Now, I've tried search but had no luck trying to find a list of tyres sizes which would fit my S Spokes.
I'd like to get a slightly wider and slightly higher profile tyre than I currently have, which are the standard Dunlops originally fitted.
Thanks,
Mike.
