ComputeTyres2Rims

Calculate tyre sizes when you are changing tyres on your car.

When you are changing tyres and rims on your car, this little program will take all the risk of you fitting the wrong size tyre,calculating to within 2.5% difference, which would be the maximum you could use to keep the speed as near as possible to the original setting.

Say your cars original tyres were 165/65/15, and you are fitting 215/40/18 to your car,this Compute Tyre Sizes App would work it out for you, so you could get as close to the original diameter as possible.
