The speed rating of a tire is based on U.S. Government standards for reaching and sustaining a specified speed. Typically, a tire with a higher speed rating results in better handling. Speed ratings are determined via laboratory tests that simulate road performance at various speeds. Tires are assigned a single letter (such as H or V) to designate speed rating.
OE means “Original Equipment” and refers to the tires included with a new vehicle at the time of purchase. The vehicle’s manufacturer selects these tires to provide the optimal performance based on the performance characteristics of the vehicle. “OEM” stands for “Original Equipment Manufacturer”.
