Load Index

A tire’s load index is a two- or three-digit numerical code that indicates the tire’s maximum load capacity. It ensures that the tires can handle the vehicle’s weight, the occupants, and an additional load.

Each load index value corresponds to a particular max load capacity in pounds or kilograms. For instance, a tire with a load index of 95 can carry up to 1,521 pounds (690 kilograms), while a tire with a load index of 110 can handle 2,337 pounds (1,060 kilograms).

Check out the relationship between the speed rating and the load index here.

It’s important to note the following:

  • Lower inflation pressure reduces the load-carrying capacity and compromises the tire safety and performance.
  • When selecting tires for a vehicle, it is essential to choose tires with a load index that meets the requirements specified by the vehicle manufacturer. 

The Ply Rating Explained

The ply rating indicates the strength and load-carrying capacity of a tire. But it is no longer directly linked to its construction and the number of layers it possesses.

Thanks to advancements in tire engineering and materials, it is now possible to achieve higher tire strength and capacity without the need for additional layers.

  • Both E1 and SL tire labeling systems no longer use ply ratings as a direct indicator of tire construction.
  • Instead, they rely on the load rating, load index, haul range, and speed rating to provide information about a tire’s capabilities.

You can check out the ply rating here.

  • E – Rated Tires: E1 tires follow the European Tyre and Rim Technical Organisation (ETRTO) standards. E-rated tires have a ply rating of 10 which corresponds to a load range rating of E.
  • Sl Tires: Sl tires represent standard load range tires. They follow the Department of Transportation (DOT) standards used in North America. The SL tires have a ply rating of 4, equal to a load range rating of B.
