BRIAN46 Posted January 27, 2010 Share Posted January 27, 2010 How do you determine what size tire & wheels you have in a kit. If there is any references for this let me know . Thanks Brian46 Quote Link to comment Share on other sites More sharing options...
shadetree Posted February 1, 2010 Share Posted February 1, 2010 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 Quote Link to comment Share on other sites More sharing options...
Rider Posted February 1, 2010 Share Posted February 1, 2010 (edited) 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. Edited February 1, 2010 by Plastic Freak Quote Link to comment Share on other sites More sharing options...
