The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 265 × 55% = 145.8 mm ÷ 25.4 | 5.74 in |
| Overall height | 19 + 2 × 5.74 | 30.48 in |
| Width | 265 mm ÷ 25.4 | 10.43 in |
| Circumference | π × 30.48 | 95.7 in |
| Revs per mile | 63,360 ÷ 95.7 | 661.8 |
With a 5.7 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.
