Tyre Speed & Load Ratings

The most important aspect of your tyre is the inflation pressure. Speed and load ratings are all based on the correct pressure being maintained. If the pressure is not as recommended by your vehicle manufacturer, none of the tables below will apply.

Tyre Speed rating

The maximum speed (based on a test of 10 minutes duration) a tyre can be operated at, when loaded according to it's Load Index and when inflated to it's recommended pressure.

Speed Rating Km per Hour
M 130 km/h
N 140 km/h
P 150 km/h
Q 160 km/h
R 170 km/h
S 180 km/h
T 190 km/h
U 200 km/h
H 210 km/h
V 240 km/h
W 270 km/h
Y 300 km/h

The speed rating Z is still included in some tyres size markings. Z rating indicates capacity for speeds in excess of 240km/h or 300km/h, depending on the specific tyre. Z rated tyres may also be marked with W or Y after the load index. If you are uncertain if the tyre you are selecting fits with your vehicles capabilities, please contact the tyre manufacturer.

Tyre load index table

The maximum mass each tyre can carry, based on the respective Load Index, at the speed indicated in it's Speed Index, when inflated to it's recommended pressure, up to 210km/h (240km/h on ZR).
