Consider the numbers:Tom D said:I am trying to decide what size tyres I will run here. I have a choice between 16 and 17 inch tyres and wheels. I'm trying to decide between 205/45/16 or 225/45/17. Our competition requires that we use factory wheel width with an offset no more than 1/4" wider (or narrower) than stock. I do not know if the 225/17's will clear the wheel wells and/or spring perches on the MINI, I presume that the 205/16's will fit. Do you know what the maximum tyre width is that will fit under a MINI on factory 16 and 17" wheels?
