Oooh! What a great little app. I will plug some numbers in it when I get home tonight. Thanks Morris
With the tyre size you will probably get a more accurate figure if you measure the circumference of the tyre than by using the tyre size.
The easiest way to measure the circumference is to make a mark on the sidewall of the tyre at the bottom and another mark on the ground next to the mark on the sidewall, then roll the car one tyre revolution till the mark on the tyre is at the bottom and make another mark on the ground then measure the distance between the two marks. (if any of that makes sense?)
