Tyre Load Rating Index Conversion Chart

Tyre Load Rating Index Conversion Chart

To work out if your tyres or tyres you are going to purchase are strong enough to carry the weight of your vehicle or caravan you will need the load index from the tyres side wall

The load index usually located just after or near the tyre size (see image below)

The image has a load rating of 97 which is 730kg, if we wanted to know what the maximum weight a 97 load rated tyre could carry we would have to times 730kg by how many load bearing tyres the vehicle had.

For example if the vehicle had four wheels / tyres with an 97 load rating the maximum weight the vehicle and the load it can carry would be 2920kg.

97 load rating is 730kg x 4 (wheels) = 2920kg
