ComputeTyres2Rims

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.
