| Measure | Inches | Millimetres |
|---|---|---|
| Overall height | 25.49 in | 648 mm |
| Section width | 8.07 in | 205 mm |
| Sidewall height | 5.25 in | 133.2 mm |

The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 205 × 65% = 133.2 mm ÷ 25.4 | 5.25 in |
| Overall height | 15 + 2 × 5.25 | 25.49 in |
| Width | 205 mm ÷ 25.4 | 8.07 in |
| Circumference | π × 25.49 | 80.1 in |
| Revs per mile | 63,360 ÷ 80.1 | 791.2 |
With a 5.2 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.
