Tire size indicator

Two-part indication of tire size: N – D
N = tire width at the largest point, indication in inch
D = diameter of the tire seat, indication in inch, equal to the wheel hub size
Example:
5.00-5 = tire width 5′′ respectively 127 mm and tire seat 5′′
4.00-6 = tire width 4′′ respectively 102 mm and tire seat 6′′

Two-part indication of tire size: M x N
M = outer diameter of the tire, indication in mm or in inch
N = tire width at the largest point, indication in mm or in inch
Example:
210×65 = Outer diameter of the tire 210 mm, tire width 65 mm

Three-part indication of tire size: M x N – D
M = outer diameter of the tire, indication in mm or in inch
N = tire width at the largest point, indication in mm or in inch
D = diameter of the tire seat, indication in inch, equal to the wheel hub size
Example:
380×150-5 = outer diameter of the tire 380 mm, tire width 150 mm, tire seat 5′′ respectively 127 mm
15×6.00-5 = outer diameter tire 15′′/380 mm, tire width 6′′/150 mm, tire seat 5′′

Please note that deviations of the outer diameter of the mounted tire are possible, depending on the wheel hub.
