what is load index 109

Introduction:

Load index is an important factor that is considered while selecting car tires. It is an indicator of how much weight each tire can support. The load index number represents the maximum load carrying capacity of a tire at a specific air pressure. In this article, we will discuss in detail what load index 109 means.

What is Load Index:

Load index is represented by a number, which ranges from 0 to 279. The number indicates the tire's load-carrying capacity. Load index of a tire is calculated by dividing the maximum load-carrying capacity of a tire by a standard load. In general, a car tire with higher load index is capable of carrying more weight.

Meaning of Load Index 109:

Load index 109 is a numerical indication of the tire's load-carrying capacity. In simple words, it means that the tire can carry a maximum weight of 1030 kg. The tire's load-carrying capacity reduces as the speed of the car rises. Hence, it is important to follow the car manufacturer's recommendation on tire size and load index.

Interpreting Load Index:

It is important to understand the load index rating while selecting tires for your car. The tire's load index should be equal or greater than the vehicle's gross axle weight rating. Overloading tires can lead to tire damage or even worse, accidents. The load index also impacts the tire's rolling resistance, which can affect fuel economy. Hence, it is crucial to match the tire's load index with the car's weight and speed rating.

Conclusion:

Load index plays a vital role in the performance of car tires. Load index 109 implies that the tire's maximum load-carrying capacity is 1030 kg. It is important to follow the car manufacturer's recommendation on tire size and load index. Overloading tires can lead to tire damage and even accidents. Hence, it is essential to match the tire's load index with the car's weight and speed rating.
