Load index truck tyres

The load index is mentioned on the side of the tyre and is always mentioned together with the speed index. The load index indicates precisely how much weight the tyre is able to cope with (at the correct tyre pressure). Never exceed the load index mentioned on the tyre!

In this example (see image), the first figure (154) indicates the tyre's maximum load (in terms of weight) if it is mounted in single configuration. The second figure (150) also indicates the weight category, but when the tyre is mounted in a double configuration. The figure ‘154’ means the tyre has a maximum load capacity of 3,750 kg - ‘150’ represents 3,350 kg.

Tyre pressure

A tyre's maximum load capacity only applies if the tyre also has an appropriate tyre pressure. Regularly checking tyre pressure has several positive effects:

  • the truck/trailer can be loaded to the maximum limit;
  • the tyre will have a longer life-span;
  • there will be a positive impact on fuel economy; and 
  • improved safety is guaranteed. 

Insufficient pressure can cost companies (a lot of) money.

Identical!

When changing tyres, it is important for the load index of the new tyre to be the same as that of the original tyre. A higher load index isn't a problem, but a lower load index should never be selected. Tyres will only be safe if this basic principle is complied with. If tyres with an identical load index are mounted on a single axle, the required minimum load index applies to each tyre on the axle. If a tyre on one side has a high load index, this will in no way compensate for a tyre on the other side of the same axle, which has an insufficient load index.
