What Is The Load Index Of Tyres


Before you decide to help your friend move or go on a holiday with lots of stuff, do you even know the carrying capacity of your tyres? Not every tyre is the same, and thus not every tyre can support the same amount of weight. Depending upon their size and design, the tyres are meant to carry only up to a specific weight.


It is the maximum load that each of your tyres can carry at the maximum speed limit. Usually, this limit is mentioned on the sidewall of your tyre in the form of a 2 or 3 digit number. The Load Index indicates the maximum weight that the tyre can support when adequately inflated. Hence, a higher tyre load index means a greater load-carrying capacity. It is always recommended to stick to the mentioned number or higher than that while buying a new set of car tyres Coventry.


How would you efficiently use your tyres you don’t know their actual capabilities? It is important to know the true nature of the type of tyres your vehicle has. One mistake that people often make is that they burden their vehicles with a lot of loads beyond the tyres’ carrying capacity. This affects the overall performance of the vehicle and also cuts down the durability of the tyres. Due to overloading, the tyres wear prematurely or may even burst. tyre blowouts can cause severe damage to the vehicle or even cause grave injuries to the passengers and other people on the road. Thus, overloading your tyres is never a good idea!

Imagine yourself carrying a weight of 100kgs and walking on the road. Your legs would start trembling under such a huge amount of weight. Forget about walking! Well, the same goes for your tyres. Not only it affects the tyres, but it also puts a heavy and unnecessary load on the engine. This may lead to the engine getting heated and even damaging it if ignored. All these factors contribute to depleting the performance of your vehicle. Overloading leads to premature treading of the tyres as well. Hence, it is extremely important to always check the load capacity of your tyre before putting a huge amount of weight on it. This ensures the safety of the driver and other people on the road too.

If you want to increase the load-carrying capacity of your vehicle, opt for a tyres Tamworth with a higher load index than your original equipment (OE)tyres. This will increase the amount of weight your vehicle can support at maximum speed. A tyre with a load index equal to the Original equipment indicates equivalent load-carrying capacity. However, if you choose tyres with a lower load index, it will decrease the overall load-carrying capacity than the original equipment tyres.


The tyre load index is usually mentioned on the tyre’s sidewalls between the diameter reading and the speed rating, besides tyre size information. The load index of passenger cars and light trucks range from 70 to 126. So, if your car has a load index of 72, then your car can support 783 pounds (or 355 kgs) of weight while moving at its maximum speed. Sometimes there are two load indexes mentioned on the sidewall. Now, the question arises which one is the correct load index? The answer is both. Load index may vary in different situations and different use of the tyres. For example, LT tyres are used on trucks with dual rear wheels and have two load indexes. The first one indicates when the tyre is installed on a single-wheel rear axle truck, while the second one denotes the dual rear application.

All in all, it is best to always carry the load following the load index of the vehicle to optimally use the tyres to their maximum capacity. It is necessary to stick to the number specified by the manufacturer for best performance.
