I often wonder what the difference is between imperial- and metric specced tyres, and what the circumference of different tyres are.

When changing rim-size, you may want to keep your circumference or "rolling radius" close to the original spec.

I found the following handy tool to help with these calculations: TYRE SIZE CALCULATOR

Hope some of you also find it useful...
