Tyre Load Rating/Index - What Does It Mean?

Are you in the market for new tyres?

If so, you might have come across terms like “tyre load rating” or “tyre load index.”

What do these terms mean, and why are they important when buying tyres? Let's find out!

What Is Tyre Load Rating?

The tyre load rating, or tyre load index, is a numerical code that indicates the maximum weight or load that a tyre can safely carry at its maximum speed.

It plays a vital role in determining the tyre’s load-carrying capacity, making it an essential factor to consider when selecting the right tyres for your vehicle.

Understanding The Tyre Load Rating Code

The tyre load rating is represented by a number that corresponds to a specific weight limit in kilograms or pounds. The higher the load rating, the more weight the tyre can support.

To comprehend this code better, let’s break it down with an example:

Suppose you have a tyre with a load rating of 90. To find the maximum load capacity, you can refer to load rating charts provided by tyre manufacturers or retailers.

A load rating of 90 typically translates to a maximum load of around 600 kilograms.

Below is a table listing various tyre load ratings and their corresponding maximum loads or weights.

Load Rating For Different Vehicles

Different types of vehicles have different load rating requirements. For instance, a heavy-duty truck would need tyres with a much higher load rating compared to a small passenger car.

When selecting tyres, consider the specific load rating recommendations for your vehicle, which can often be found in the owner’s manual or on the placard on the driver’s side door.

Importance Of Load Rating For Your Vehicle

Each vehicle is designed with specific load requirements, and adhering to them is crucial for safety and optimal performance.

Exceeding the load capacity can put undue stress on the tyres, suspension system, and other crucial components, leading to potential hazards on the road.

Furthermore, considering factors like passenger count, cargo weight, and road conditions will help you determine the appropriate load rating for your vehicle’s tyres.

Whether you have a compact car, SUV, truck, or any other vehicle, the load rating should align with the manufacturer’s recommendations.


Understanding the significance of tyre load ratings is paramount when choosing the right tyres for your vehicle.

The last thing you want is a tyre blowout because you’ve used inappropriate tyres for your vehicle!
