The closer you can get the overall height to the OEM SS 1LE tire specs the closer the speedo/odometer will be and the happier the ABS computer will be also.

Here is the formula to calculate tire height, this way you can run the sizes thru and see which is closer.

Based on a 305/30-20 tire size:

- 305 x .30 = 91.5mm

- 91.5mm / 25.4mm = 3.60"

- 3.60" x 2 = 7.20"
(The 3.6" is how tall each tire is from the ground to the wheel, multiply by 2 since there is a top and bottom.)

7.2" + 20" (Wheel size) = 27.20" tall tire
