Useful tool for comparing multiple wheel and tyre combinations

I have found Calculator 1 on the web page to which this is a link very useful. It shows the whole range of wheel and tyre size combinations that are within 1% rolling circumference of whatever reference size you put in. Ciao a tutti.

1% difference wouldn't include most alternative tyre sizes that are popular with A2 owners.

185/60R15 and 195/50R16 have a rolling circumference around 2% more than standard.

185/60R14 and 195/50R15 have a rolling circumference around 2.5% less than standard.

However, 195/55R15 and 205/45R16 are within 1% difference so would be included.
