Tyre Load Ratings
All tyres for every vehicle will have a Load Rating. This measurement is important to the vehicle's performance and your safety.
Before buying your tyres it is important that you check for the correct Load Rating. The Load Rating is decided by the manufacturer based on what weight the tyres need to support. The weight your tyres need to support includes that of the vehicle and also what you could reasonably and safely want to transport in your vehicle.
When considering tyres for your vehicle, a tyre with a lower Load Rating than required could invalidate your insurance and increase the chance of product failure.
Where to find the correct Load Rating for your vehicle.
- Check the vehicle handbook
- If you have had the vehicle from new look at the current tyres
- Contact the garage, dealership or vehicle manufacturer
Choosing a Load Rating which is higher than required is acceptable, but choosing one which is lower than your vehicle needs is not.
If you have a tyre with a Load Rating of "91" as specified by your vehicle handbook, this indicates a maximum weight per tyre of 615kg. When selecting a replacement tyre; a rating of "90" or below should not be selected as a replacement, while a tyre with a Load Rating of "92" and above will be suitable.
Load Ratings are based on scientific stress tests which help to calculate the optimum tyre requirements.
In the typical tyre size example below, the Load Rating can be found next to the Speed Rating.
