Tire Ratings


Tires are rated by load capacity, size and speed capacity. For example, a P225/50VR16 printed on the side of the tire means:

P = P-Metric (Passenger Type Tire)
255 = Section Width (255mm)
50 = Aspect Ratio (tire height/section width)
V = Speed Rating
R = Type of Ply (Radial)
16 = Wheel Diameter (16 inches)

Tire and wheel dimensions are the first point of information in any discussion of size and capacities. Among the other terms used to describe tires are: tread, shoulder, carcass, sidewall, bead seal, bead seat, tire diameter, aspect ratio, speed rating and section width.
