In our example, we see that the tyre load rating of 91 corresponds to a maximum tyre load of 615 kg.
What does XL on tyres mean?
Some tyres are also marked XL. This stands for "Extra Load".
It simply means that the tyre has been reinforced to be able to carry heavier loads than standard tyres of the same dimension. This type of tyre is generally used on heavier vehicles, for example SUVs .
Can I switch to a tyre with a higher load rating ?
As mentioned above, tyres of the same size can have different load ratings. When replacing worn tyres, it is recommended that tyres with the original manufacturer’s load rating (and speed rating), as well as the original dimensions, should be fitted.
Anyway “who can do more can do less” and it is of course possible to fit your car with tyres that have a higher load rating than the manufacturer’s specification. However, you will not necessarily be able to carry more load than the original manufacturer’s specification because there is a limit on the maximum permissible axle load for your vehicle, independent of the tyre load capacity.
What about the size? Is it possible to change it?
You can find the answer to this question in our article on changing the size of a tyre.
