Load Index

The LOAD INDEX is a numerical code associated with the maximum load a tyre can carry (except for loads at speeds above 210km/h ) at a speed indicated by its Speed Symbol under service conditions specified by the tyre manufacturer.

Passenger car tyres - Load capacities and speed limits

The load capacity quoted in the Standard Manual is the maximum load "per tyre" permitted for speed "up to and including 210 km/h".
For speed in excess of 210 km/h, the maximum load per tyre shall not exceed the following percentages of the load capacity quoted in the following table, depending on the type of tyre and on the speed capability of the vehicle.

For ZR Tyres, where no Service Description is shown, the Maximum Load capacity shown in the Technical Manual applies. The actual speed capabilities, load capacities and the relevant inflation pressures will be agreed between vehicle and tyre manufacturers (or their national associations) taking into consideration the vehicle characteristics and type of service.
In the absence of such agreement, it is recommended that for speed capabilities between 240 and 270 km/h, the load capacities and the relevant inflation pressures of ZR tyres be the same as for tyres "W" speed symbol, up to the maximum speed certified by the tyre manufacturer.

Percentage of Load capacity (%)

versus Speed (1)

Speed Capability of the vehicle (Km/h)	Speed Symbol H%	Speed Symbol V%	Speed Symbol W%	Speed Symbol Y%
210	100	100	100	100
220	-	97	100	100
230	-	94	100	100
240	-	91	100	100
250	-	-	95	100
260	-	-	90	100
270	-	-	85	100
280	-	-	-	95
290	-	-	-	90
300 (2)	-	-	-	85

(1) For intermediate maximum speeds, linear interpolations of the tyre load capacity is permitted.
(2) For speed capabilities over 300 km/h, the percentage of the load capacities and the relevant inflation pressures will be agreed between vehicle and tyre manufacturers (or their national associations) taking in to consideration the vehicle characteristics and the type of service. In any case the load capacity over 300 km/h should not exceed 85% of the load indicated by the Load Index.
