The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 265 × 65% = 172.2 mm ÷ 25.4 | 6.78 in |
| Overall height | 17 + 2 × 6.78 | 30.56 in |
| Width | 265 mm ÷ 25.4 | 10.43 in |
| Circumference | π × 30.56 | 96.0 in |
| Revs per mile | 63,360 ÷ 96.0 | 659.9 |
With a 6.8 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.
