The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 225 × 65% = 146.2 mm ÷ 25.4 | 5.76 in |
| Overall height | 17 + 2 × 5.76 | 28.52 in |
| Width | 225 mm ÷ 25.4 | 8.86 in |
| Circumference | π × 28.52 | 89.6 in |
| Revs per mile | 63,360 ÷ 89.6 | 707.3 |
With a 5.8 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.
