Load Speed Index of OTR Tires

The OTR tire load speed index lets you know the load-carrying capacity of the tyre. In other words, it’s the amount of weight your tire can support safely.

The Load Index is an international numerical code for the maximum load a tire can carry at the speed indicated by its speed symbol under service conditions specified by tire brands. This load index can always be found in combination with the speed index (max speed).

Example – 23.5R25 Magna MA02 LSI = 185B –> 9250 kg/5.0 Bar
185 Represents a maximum load capacity 9250 kg or 20.390 Lb.
B Represents a maximum speed of 50 km/h.

Below you will find the Speed Symbols:

Speed Symbol	Speed (km/h)
A1	5
A2	10
A3	15
A4	20
A5	25
A6	30
A7	35
A8	40
B	50
C	60
D	65
E	70
F	80
G	90
J	100
K	110
L	120
M	130
