The working
- 205/55R16: sidewall = 205 mm × 55% = 112.8 mm = 4.44 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 4.44 = 24.88 in (632 mm).
- Circumference = π × 24.88 = 78.2 in; revolutions per mile = 63,360 ÷ 78.2 = 811.
- 205/60R16: sidewall = 205 mm × 60% = 123.0 mm = 4.84 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 4.84 = 25.69 in (652 mm).
- Circumference = π × 25.69 = 80.7 in; revolutions per mile = 63,360 ÷ 80.7 = 785.
- Speedometer. True speed = what it shows × new diameter ÷ old = 60 × 25.69 ÷ 24.88 = 61.9 mph.
- Ground clearance. Half the change in diameter: (25.69 − 24.88) ÷ 2 = +0.40 in.
Speedometer
A 205/60R16 turns 785 times a mile against the 205/55R16’s 811. With a speedometer set for 205/55R16, true speed is what it shows × 25.69 ÷ 24.88:
| 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: +0.40 in (+10 mm), half the change in diameter.
- Top of the tread: +0.40 in (+10 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 4.44 to 4.84 inches.
