| Measure | Inches | Millimetres |
|---|---|---|
| Overall height | 25.63 in | 651 mm |
| Section width | 8.86 in | 225 mm |
| Sidewall height | 5.31 in | 135.0 mm |

The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 225 × 60% = 135.0 mm ÷ 25.4 | 5.31 in |
| Overall height | 15 + 2 × 5.31 | 25.63 in |
| Width | 225 mm ÷ 25.4 | 8.86 in |
| Circumference | π × 25.63 | 80.5 in |
| Revs per mile | 63,360 ÷ 80.5 | 786.9 |
With a 5.3 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.
