The working
- 215/60R17: sidewall = 215 mm × 60% = 129.0 mm = 5.08 in.
- Diameter = rim + 2 × sidewall = 17 + 2 × 5.08 = 27.16 in (690 mm).
- Circumference = π × 27.16 = 85.3 in; revolutions per mile = 63,360 ÷ 85.3 = 743.
- 225/60R17: sidewall = 225 mm × 60% = 135.0 mm = 5.31 in.
- Diameter = rim + 2 × sidewall = 17 + 2 × 5.31 = 27.63 in (702 mm).
- Circumference = π × 27.63 = 86.8 in; revolutions per mile = 63,360 ÷ 86.8 = 730.
- Speedometer. True speed = what it shows × new diameter ÷ old = 60 × 27.63 ÷ 27.16 = 61.0 mph.
- Ground clearance. Half the change in diameter: (27.63 − 27.16) ÷ 2 = +0.24 in.
Where the 215/60R17 numbers come from
The section width is 215 mm (8.46 inches), and each sidewall is 60% of it: 129.0 mm, or 5.08 inches. Two sidewalls and the 17-inch rim make 27.16 inches (690 mm).
One turn covers π × 27.16 = 85.3 inches, so the tire turns 743 times a mile and 461 times a kilometer.
