The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 165 × 65% = 107.2 mm ÷ 25.4 | 4.22 in |
| Overall height | 14 + 2 × 4.22 | 22.44 in |
| Width | 165 mm ÷ 25.4 | 6.50 in |
| Circumference | π × 22.44 | 70.5 in |
| Revs per mile | 63,360 ÷ 70.5 | 898.6 |
With a 4.2 in sidewall this is a medium sidewall: a balance of cushion and response. Real tires vary by brand and model, and the loaded radius under the vehicle is a bit smaller than this unloaded figure.
