great tyre size calculator to work out mph

[surf-wejd]

hi all,
i have found a great tyre size calculator for people who have changed to bigger tyres, or smaller for some reason.
i found it very useful to know what speed i am actually doing with bigger tyres on, anyway enjoy.
by the way the stock size for a surf is 265/70/15
