The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 195 × 65% = 126.8 mm ÷ 25.4 | 4.99 in |
| Overall height | 15 + 2 × 4.99 | 24.98 in |
| Width | 195 mm ÷ 25.4 | 7.68 in |
| Circumference | π × 24.98 | 78.5 in |
| Revs per mile | 63,360 ÷ 78.5 | 807.4 |
With a 5.0 in sidewall this is a medium sidewall: a balance of cushion and response. Real tires vary by brand and model, and the loaded radius under the vehicle is a bit smaller than this unloaded figure.
