The working
- 225/60R16: sidewall = 225 mm × 60% = 135.0 mm = 5.31 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 5.31 = 26.63 in (676 mm).
- Circumference = π × 26.63 = 83.7 in; revolutions per mile = 63,360 ÷ 83.7 = 757.
- 225/65R16: sidewall = 225 mm × 65% = 146.3 mm = 5.76 in.
- Diameter = rim + 2 × sidewall = 16 + 2 × 5.76 = 27.52 in (699 mm).
- Circumference = π × 27.52 = 86.4 in; revolutions per mile = 63,360 ÷ 86.4 = 733.
- Speedometer. True speed = what it shows × new diameter ÷ old = 60 × 27.52 ÷ 26.63 = 62.0 mph.
- Ground clearance. Half the change in diameter: (27.52 − 26.63) ÷ 2 = +0.44 in.
Where the 225/60R16 numbers come from
The section width is 225 mm (8.86 inches), and each sidewall is 60% of it: 135.0 mm, or 5.31 inches. Two sidewalls and the 16-inch rim make 26.63 inches (676 mm).
One turn covers π × 26.63 = 83.7 inches, so the tire turns 757 times a mile and 471 times a kilometer.

About 26.6x8.9R16: 26.6 inches tall and 8.9 inches wide on a 16-inch wheel, with 5.3-inch sidewalls. Exactly, 16 + 2 × 225 mm × 0.60 ÷ 25.4 = 26.63 inches.
How many revolutions per mile does a 225/60R16 make?
757 by its diameter: 63,360 inches in a mile ÷ 83.7 inches a turn. Tire makers’ published figures are measured under load, when the tire rolls on a slightly smaller radius, and run 2.8% to 3.3% higher in Toyo’s tables.
Is LT225/60R16 the same size as P225/60R16?
In dimensions, yes: the numbers mean the same in every metric size. The letters mark what the tire is built for, and an LT tire’s load is rated differently, so check the load index and pressure your vehicle needs before swapping one for the other.
