LOAD INDEX & SPEED SYMBOLS

On the sidewall of all Huaan tires you can find  the Load Index and Speed Symbol  for that tyre (following the key sidewall markings) for example 105 S.  

LOAD INDEX  

The load rating  (represented by the numerical value) is related to the maximum weight that tyre  can carry. So in this case 105 would refer to a load capacity of 925kg, with  most passenger vehicle load indexes range from 62 to 126. 

◆ In all instances the  tyres load index must meet or exceed the value displayed on the vehicles  placard.  

SPEED  SYMBOL

The speed category  symbol, for example 'S', indicates the maximum speed at which the tyre can carry  a load corresponding to its load index. So in this case, 'S' would refer to a  maximum speed of 180km/hour.

See the chart below  for a full list of speed symbols and their applicable values. 

*A tyre with ZR  symbols have a speed capability of over 204km/h. We can always consult with the  technology department to ascertain the tyres actual speed  capabilities.

PLY RATING  

Ply ratings identify  the load carrying capacities of a tyre in terms of plies. Ply rating originally  referred to the number of cotton layers used to strengthen a tyre's casing.  Today, when tyres are labelled 10-ply for example, they are no longer actually  constructed of 10 individual layers of cotton, but they do offer the equivalent  strength. Over time, steel ply and radial construction replaced cotton, leading  to a new distinction: Load Range. Load Range identifies the maximum amount of  weight that can be placed on a tyre horizontally, which varies depending on tyre  size and inflations limits.
