It is not recommended to mix tyre load ratings on a vehicle. The tyre load rating is a measure of a tyre's maximum carrying capacity, and it is determined by the tyre's construction and materials.

Tyres with different load ratings may have different levels of strength and durability, and mixing them could compromise the overall performance and safety of a vehicle.

When selecting tyres for a vehichle, it is important to choose tyres with the same load rating as the manufacturer recommends.

If you are unsure about the correct tyre load rating for your vehicle, you can consult your vehicle's handbook or consult a tyre professional to ensure that you select the right tyres for your vehicle.
