Load & Speed Ratings

The Load Index is a numerical code associated with the maximum load a tyre can carry at the speed indicated by its Speed Category symbol under specified conditions up to 210km/h. Using a 215/60R16 95T tyre size as an example, the 95T at the end of the size represents the tyre's service description. A service description identifies the tyre's load index and speed rating. The first two digits - 95 - represent the tyre's load index and are followed by a single letter - T - identifying the tyre's speed rating.

Load Index

215/60R16 95T - The Load Index - 95 - is the tyre's assigned numerical value used to compare relative load carrying capabilities. In the case of this example the 95 identifies the tyre's ability to carry a maximum of 690 kg (1521 lbs). The higher the tyre's Load Index number, the greater its load carrying capacity. The Load Index rating also represents the load carrying capacity of the tyres when they are inflated to maximum psi so the load carrying capacity reduces as tyre pressures are reduced.

Speed Rating

Speed ratings are based on laboratory tests where the tyre is pressed against a large diameter metal drum to reflect its appropriate load, and run at ever increasing speeds until the tyre's required speed has been consistently exceeded.

Australian Vehicle Standards' rules state that passenger cars must have a tyre speed rating of S (180 km/h) or greater. It is not a legal requirement to match the tyre placard's speed rating so long as it is not less than S (180 km/h). The speed rating must be stamped on the tyre.

It is important to note that speed ratings only apply to tyres that have not been damaged, altered, under-inflated or overloaded. A tyre that has been cut or punctured no longer retains the original speed rating, even after being repaired.

Disclaimer: While a speed symbol is an indication of the speed capability of the tyre, we do not endorse the operation of any vehicle in excess of legal speed limits.
