Tyre Load Rating
On the sidewall of your tyres you'll find a series of numbers and letters which denote the tyre's specification. They'll look similar in format to this: 195/55 R17 90 W. For many drivers, these may appear confusing and leave you wondering what exactly they’re for. This brief guide will provide you with all the details you need about this important coding.
What do Tyre Ratings Mean?
The number at the end (90 in this example) is the tyre's load rating index. It is used to determine the maximum load your tyres can safely support, including vehicle weight, passengers, luggage, and towage. It is important drivers understand the weights involved in order to determine the weight they may, or may not, put their tyres under.

Tyre Load and Speed Ratings
As you can see from the table above, our example tyre with a load rating of 90 can support a maximum weight of 600kg.
Manufacturers decide which tyre specifications are to be used on specific vehicle models and they base their decision on the weight of the vehicle and expected load usage. Your vehicle handbook will provide this information so you can choose the right tyres for your vehicle with the correct tyre load rating.
Important: For your safety and peace of mind, you must run tyres with the correct load rating for your vehicle. Tyres with a higher load rating are fine to run, but tyres with a lower load rating are potentially dangerous to use on your vehicle, and may invalidate your insurance.
