Tire Speed Ratings

Important: When replacing tires, never install a tire that is a smaller size or a lesser speed rating than that used as original equipment.

Speed Symbol S T U H V Z
Maximum Speed (km/h) 160 190 200 210 240 Over 240
Maximum Speed (mph) 112 118 124 130 149 Over 149

Important: These speeds apply only at the tires full air pressure. An underinflated tire will not meet it's speed rating capability.
