How we calculate it

In 37x13.5R24, 37 is the overall-diameter code in inches, 13.5 is the width code in inches and 24 is the wheel diameter in inches.

Overall diameter = 37 × 25.4 = 939.8 mm
Section width = 13.5 × 25.4 = 342.9 mm
Sidewall height = (939.8 − 24 × 25.4) / 2 = 165.1 mm
Circumference = π × 939.8 ≈ 2,952.5 mm
