The working
- 35x12.50R17LT: 35.00 in tall and 12.50 in wide, as the size says.
- Sidewall = (diameter − rim) ÷ 2 = (35 − 17) ÷ 2 = 9.00 in.
- Circumference = π × 35.00 = 110.0 in; revolutions per mile = 63,360 ÷ 110.0 = 576.
- 37x12.50R17LT: 37.00 in tall and 12.50 in wide, as the size says.
- Sidewall = (diameter − rim) ÷ 2 = (37 − 17) ÷ 2 = 10.00 in.
- Circumference = π × 37.00 = 116.2 in; revolutions per mile = 63,360 ÷ 116.2 = 545.
- Speedometer. True speed = what it shows × new diameter ÷ old = 60 × 37.00 ÷ 35.00 = 63.4 mph.
- Ground clearance. Half the change in diameter: (37.00 − 35.00) ÷ 2 = +1.00 in.
Where the 35x12.50R17 numbers come from
A flotation size names its height and width: 35 inches tall and 12.5 inches wide, on a 17-inch rim. Each sidewall is what’s left: (35 − 17) ÷ 2 = 9.00 inches, so the sidewall is 72% of the width.
One turn covers π × 35.00 = 110.0 inches, so the tire turns 576 times a mile and 358 times a kilometer.

Questions
How tall is a 35x12.50R17 tire really?
35 inches by its name. Measured inflated, the makers’ tables on this page give 34.5 to 34.84 inches. Tread depth and the rim it’s measured on make the difference.
How many revolutions per mile does a 35x12.50R17 make?
576 by its diameter: 63,360 inches in a mile ÷ 110.0 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.
What metric size is closest to 35x12.50R17?
Of the common 17-inch sizes, 315/70R17: 0.64 inches (16 mm) shorter and 0.10 inches (2 mm) narrower.
Is 35x12.50R17 an LT tire?
Yes. Bridgestone’s guide describes flotation sizes as light-truck tires, written with LT after the rim: 35x12.50R17LT. They carry one load index, as they’re not made to run as duals.
