The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 165 × 70% = 115.5 mm ÷ 25.4 | 4.55 in |
| Overall height | 13 + 2 × 4.55 | 22.09 in |
| Width | 165 mm ÷ 25.4 | 6.50 in |
| Circumference | π × 22.09 | 69.4 in |
| Revs per mile | 63,360 ÷ 69.4 | 912.8 |
With a 4.5 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.
