The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 195 × 50% = 97.5 mm ÷ 25.4 | 3.84 in |
| Overall height | 15 + 2 × 3.84 | 22.68 in |
| Width | 195 mm ÷ 25.4 | 7.68 in |
| Circumference | π × 22.68 | 71.2 in |
| Revs per mile | 63,360 ÷ 71.2 | 889.4 |
With a 3.8 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.
