Brian,

First read the sidewall of the kit tire. This should get you in the ballpark. I have found most kit tires are pretty close to the stated size.

As an example a 1:1 P225-70R15 is 225 millimeters wide with a 157.5mm high sidewall (70% of width) to fit a 15 inch rim. Also the P stands for

passenger. An LT would be light truck. So in 1/25 that tire is 9mm wide with a 6.3mm sidewall fitting a rim about 9/16 in diameter.

For the older alpha-numeric (G70/15) contact your local tire store for a conversion chart or maybe Coker Tire on the web.

For plain sidewall generic tires measure the tire and multiply by whatever scale your useing.

Hope this helps,

Marc

To do the math on percetages for the side wall hight you cross multiply. For a 225/70R15 you'd mulitply 70x225 and divide by 100 then do you scale math.
