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
Thanks for the formula- the closest I can find to the stock 1LE tires is 26.8
