There are two flavors, one for U.S. designation tires and one for metric TRX designation tires. All calculations are designed to round up. Calculations are to be treated as approximate only, due to possible and probable variations in how tires are manufactured. The information in the Required area is needed to perform the comparison. The tire tread width, sidewall (aspect) ratio, and wheel rim diameter from each of the two tires to be compared, along with a speedometer reading used to compute the effect the after market tire size has on your speedometer's accuracy.The following is an example to help to decode a tire size like 195/70R15. The 195 is the tire width in millimeters, measured from the bottom of the bead to the bottom of the bead, the 70 is the sidewall aspect ratio, the ratio of sidewall height to tire width at the tread (indicating that the sidewall height is 70% of the tread width), and the 15 is the wheel rim diameter in inches. After the data entry of the required information, click on the Compare U.S. Tires button in the top calculator or Compare Metric Tires in the lower calculator to have the selected tire sizes compared. Adjusted Speedometer Reading is what speed the car will need to go if using the after market tires, to be traveling at the same speed if the car had the original tires on. It is an adjustment faster or slower from the original speed. Please select from U.S. or Metric comparisons.
I read a article under the same title some time ago, but this articles quality is much, much better. How you do this..
