Tire Speed Ratings

All tires made today are required by law to have a speed associated with them before they can get DOT approval. This number ensures that the tire will withstand highway speeds, and more on certain models designed for pricey exotics.

At a bare minimum, we here at TractionReview.com recommend no lower than “S” rated tires for normal street use. While many folks will never see 112 MPH, it’s always better to have a tire rated for a higher speed than you will ever drive at than to be at the tires limit under normal driving conditions on the highway.

Speed Rating Maximum Speed (mph) Maximum Speed (km/h) Common Applications
M 81 130
N 87 140 Spare tires
P 93 150
Q 99 160 Stud-less Snow Tires
R 106 170 Vans and Light Trucks
S 112 180 Family Sedans
T 118 190
U 124 200
H 130 210
V 149 240
W 168 270 Exotics
Y 186 300
Z 149+ 240+
(Y) 186+ 300+

+ Denotes “in excess of”. While there is no set limit, the tire was tested and approved at speeds above the indicated test level. Please note the difference between Y and (Y).
