The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 265 × 70% = 185.5 mm ÷ 25.4 | 7.30 in |
| Overall height | 16 + 2 × 7.30 | 30.61 in |
| Width | 265 mm ÷ 25.4 | 10.43 in |
| Circumference | π × 30.61 | 96.2 in |
| Revs per mile | 63,360 ÷ 96.2 | 659.0 |
With a 7.3 in sidewall this is a very tall sidewall, the kind seen on light-truck and off-road sizes, with plenty of 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.
