| RE: rims question
Where are you measuring? Your question prompted me to check the diameter of my wheels (standard 17") and I find that it is not possible to measure them when the tyre is mounted, I measured at the rim to start with and this comes to 18.7".
It seems the 17" referred to is measured internally and is the diameter of the inner surface of the wheel to which the tyre fits, so I assume a 17" tyre will measure about 17" and a little bit of clearance across the inside (17" hole in the middle).
