Found this on the web, very handy for comparing rolling radius etc.

Went looking because we've just got another Bongo fitted with 17" wheels and I wanted to know what the rolling radius of the 227x 50 17 tyres is.
Surprised to see that it is actually less than the standard 215x65x15 wheels I have. So the speedo's actually running a bit slow in comparison. Still about 3% fast though according to the GPS.
