Speed Chart

Maximum speed rating at which a tire can carry a load corresponding to its Load Index under specific service conditions.

Speed Symbol Maximum Speed(MPH)
Q 99
S 112
T 118
U 124
H 130
V 149
W 168
Y 186
(Y) Above 186
**Z
(open ended speed category)		 Above 149

NOTE: **For tires with speed symbols W and Y, ZR may or may not also appear within the size designation. For tires with a maximum speed above 186 MPH, a ZR must appear in the size designation. Examples of similar size markings, with and without service descriptions, and showing different maximum speeds, are shown below:

Tire Designation Maximum Speed
