The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 265 × 60% = 159.0 mm ÷ 25.4 | 6.26 in |
| Overall height | 20 + 2 × 6.26 | 32.52 in |
| Width | 265 mm ÷ 25.4 | 10.43 in |
| Circumference | π × 32.52 | 102.2 in |
| Revs per mile | 63,360 ÷ 102.2 | 620.2 |
With a 6.3 in sidewall this is a tall sidewall with more cushion and flex. Real tires vary by brand and model, and the loaded radius under the vehicle is a bit smaller than this unloaded figure.
