| Measure | Inches | Millimetres |
|---|---|---|
| Overall height | 25.75 in | 654 mm |
| Section width | 9.65 in | 245 mm |
| Sidewall height | 3.38 in | 85.8 mm |

| Revolutions per mile | 783.2 |
The math
| Step | Math | Result |
|---|---|---|
| Sidewall | 245 × 35% = 85.8 mm ÷ 25.4 | 3.38 in |
| Overall height | 19 + 2 × 3.38 | 25.75 in |
| Width | 245 mm ÷ 25.4 | 9.65 in |
| Circumference | π × 25.75 | 80.9 in |
| Revs per mile | 63,360 ÷ 80.9 | 783.2 |
With a 3.4 in sidewall this is a low-profile sidewall: sharp steering response, less cushion over bumps, and wheels that are easier to curb. Real tires vary by brand and model, and the loaded radius under the vehicle is a bit smaller than this unloaded figure.
