The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 215 × 70% = 150.5 mm ÷ 25.4 | 5.93 in |
| Overall height | 15 + 2 × 5.93 | 26.85 in |
| Width | 215 mm ÷ 25.4 | 8.46 in |
| Circumference | π × 26.85 | 84.4 in |
| Revs per mile | 63,360 ÷ 84.4 | 751.1 |
With a 5.9 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.
