The working
- 215/60R16: sidewall = 215 mm × 60% = 129.0 mm = 5.08 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 5.08 = 26.16 in (664 mm).
- Circumference = π × 26.16 = 82.2 in; revolutions per mile = 63,360 ÷ 82.2 = 771.
- 215/65R16: sidewall = 215 mm × 65% = 139.8 mm = 5.50 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 5.50 = 27.00 in (686 mm).
- Circumference = π × 27.00 = 84.8 in; revolutions per mile = 63,360 ÷ 84.8 = 747.
- Speedometer. True speed = what it shows × new diameter ÷ old = 60 × 27.00 ÷ 26.16 = 61.9 mph.
- Ground clearance. Half the change in diameter: (27.00 − 26.16) ÷ 2 = +0.42 in.
Speedometer
A 215/65R16 turns 747 times a mile against the 215/60R16’s 771. With a speedometer set for 215/60R16, true speed is what it shows × 27.00 ÷ 26.16:
| Speedometer shows | True speed | Difference |
|---|---|---|
| 25 mph | 25.8 mph | +0.8 mph |
| 35 mph | 36.1 mph | +1.1 mph |
| 45 mph | 46.5 mph | +1.5 mph |
| 55 mph | 56.8 mph | +1.8 mph |
| 65 mph | 67.1 mph | +2.1 mph |
| 75 mph | 77.4 mph | +2.4 mph |
Clearance
- Ground clearance: +0.42 in (+11 mm), half the change in diameter.
- Top of the tread: +0.42 in (+11 mm), so that much less room under the fender.
- Each side, on the same wheel: no change.
A new wheel with a different width or offset moves the tire again. The sidewall goes from 5.08 to 5.50 inches.
