TIRE LOAD AND SPEED INDEX

TIRE LOAD INDEX

The TIRE LOAD INDEX is a numerical value assigned to a tire in relation to the its load bearing capability. The greater the load index number, the higher the load-bearing capability of the tire.

SPEED INDEX

SPEED INDEX, also called speed rating of a tire, is the rating it has been designed to run at and still provide performance characteristics. This is often matched to the vehicle’s speed and performance as well as the load-bearing capability based on its load index. Please note that Milestar does not recommend the use of any tire above the legal speed limit of the road the vehicle is operating on.

Speed Symbol	MPH	KPH
L	75	120
M	81	130
N	87	140
P	93	150
Q	99	160
R	106	170
S	112	180
T	118	190
U	124	200
H	130	210
V	149	240
W	168	270
Y	186	300
Z*	149+	240+

*This is good general rule of thumb for standard passenger tires. There are some specialty products that are designed with some characteristics that would not follow this model.
