Tire Load Ratings are represented by a numerical code (load index) displayed on the sidewall of tires, indicating the maximum weight a single tire can carry at maximum pressure. Common passenger-car load indexes range from 70 (739 lbs.) to 110 (2337 lbs.), while light trucks often use load range letter (e.g. C, D, E) for higher capacities. You can find these values listed in the tire description provided on the shop page. Below is an easy to refer guide for load indexes used in common consumer tires.
Why Does Tire Load Rating Matter?
Tire load ratings matter because they determine a tire's capacity to support the weight of your vehicle and any additional load. Choosing the proper load rating is essential for safety, optimal performance and longevity of your tires. Overloading tires with a lower load rating can lead to numerous issues, including reduced traction, increased wear and the risk of tire failure.
On the flip side, using tires with a higher load rating than necessary can affect ride comfort and fuel efficiency. Selecting the correct load rating ensures that your tires can handle the expected weight and keeps you safe.
What is the load rating range for light truck tires?
The load rating range for light truck tires typically starts around 100 and can go up to 126 or higher. Light truck tires are designed to carry varying loads, and the specific load rating you need depends on your vehicle's weight and intended use.
It's important to refer to your vehicle's manufacturer recommendations or consult the tire manufacturer to determine the appropriate load rating for your specific light truck tires to ensure safety and performance.
Load Range vs Load Index
So, what's the difference between load range and load index? Simple. Load range deals with the tire's inflation pressure capabilities, while load index focuses on the tire's ability to bear weight. Both are important factors in selecting the right tire for your vehicle and its intended use. Here's a quick breakdown.
Load range:
Load range refers to the tire's ability to handle different inflation pressures and load capacities. It is usually indicated by letters like "C," "D" or "E" on the tire sidewall. A higher load range indicates a tire that can support heavier loads at higher inflation pressures.
Load index:
The load index is a numerical value that specifies the tire's load-carrying capacity. It is represented as a number, such as 94, and can be found on the tire sidewall. A higher load index signifies a greater load-carrying capacity for a specific tire size.
