Notes:

1. For most tire brands the calculated results will be more accurate if 1" is subtracted from manufacturer's stated tire size. This is due to a combination of the tendency of manufacturers to overstate tire size and the effect of vehicle load on the tire's rolling circumference

2. For TJ model Jeep Wranglers (97-06), the final drive ratio by transmission is:

- 4 speed automatic - 0.69
- 5 speed manual - 0.78
- 6 speed manual - 0.84
- 3 speed automatic - 1.00
