Hi all, I will apologise in advance for rambling on :rolleyes:

I want to fit some aftermarket 17s on my mini and wasnt sure which i could use 7x17 or 7.5x17. I believe it has to do with offset so could somebody please tell me what i would need to check,
Also tyres 205 or 215, would i be correct in thinking say 205 on 7" rim would have more overhang than stretched over a 7,5" rim?

and lastly why are 205/45 a different diameter (hieght) to 215/45 when fitted to wheel i thought the sidewall would be the same just wider ?

Thanks..... Mark

Check out tirerack.com for fitment, but I'm pretty sure a 17x7.5 will fit. I have 17x7's, which is what comes with the Cooper S Sport package. As for the tire diameter (height) on a wider tire, the sidewall height is a ratio - so if the tire is wider, the ratio will be higher. For example, 45% of 215 is more (taller) than 45% of 205. Get it?
