A Brief Guide to Tyre Load Ratings | What & Why

Shopping for your car tyre is not an easy job. If you’re driving a performance-based vehicle, you must ensure to check the load ratings of the tyre you’ll be driving it with.

Purchasing the tyres with the wrong load rating can be hazardous, as too much weight might damage the tyres and cause an accident.

With this blog, we hope to explain what load ratings are and why is it essential for you to check the load ratings of your new or old tyres.

What is Load Rating?

As the name suggests, a tyre load rating represents the maximum load or weight a moving tyre can bear, when inflated properly at the fastest speed allowed.

The rating is applicable for individual tyres and not for all four. In most cases, each of the four tyres of the vehicle is expected to have identical load ratings. It’s normally represented in numerical value. The higher the tyre’s load index number, the greater will be its load-carrying capacity.

For instance, a load index of 105 will represent a load-carrying capacity of 925 kilograms. Whereas, a load rating of 65 is equivalent to 265 kilograms.

For most passenger vehicles, the range of load index lies between 62 to 126.

Why is this Load Rating critical?

Tyre load ratings are significantly important as it prevents the drivers from installing the wrong tyres, protecting the general population from accidents that may happen due to overloaded tyres.

Due to this overloading, you might have to deal with numerous other technical problems and might book a car service in Sydney.

An overloaded tyre is one that’s carrying too much weight, more than it was designed to bear. Further, it’s also running on varied speeds with lower pressure than prescribed by its manufacturer. At such times, the underinflated tyre might cause friction, heating itself internally, which ultimately leads to a tyre blowout, completely destroying it. You must have witnessed such scenarios in loading cars and trucks.

Therefore, it’s imperative to check with your manufacturer about the load-carrying capacity of the tyres that are a fit in your car.
