The world of tires can be overwhelming, especially for those who are new to the concept of tire maintenance. One of the most important aspects of tire care is understanding the load index of your tires. But what does it mean, and why is it so crucial? In this comprehensive guide, we’ll delve into the world of load indexes, exploring what they are, how they work, and why they’re essential for your vehicle’s safety and performance.
What is Load Index?
The load index is a numerical value assigned to a tire to indicate its maximum load-carrying capacity. It’s a vital piece of information that helps ensure your vehicle is properly equipped with tires that can handle the weight and pressure it’s designed to carry. The load index is usually displayed on the tire’s sidewall, along with other important information like the tire’s size, speed rating, and tread type.
How is Load Index Calculated?
The load index is calculated based on the tire’s construction, materials, and design. Tire manufacturers use a complex formula to determine the maximum load-carrying capacity of each tire, taking into account factors like the tire’s width, aspect ratio, and tire type. The load index is then assigned a numerical value, ranging from 35 to 110, with higher numbers indicating a higher load-carrying capacity.
Load Index Scale

|---|---|
| 35 | 82 |
| 40 | 92 |
| 45 | 102 |
| 50 | 113 |
| 55 | 123 |
| 60 | 135 |
| 65 | 147 |
| 70 | 159 |
| 75 | 171 |
| 80 | 184 |
| 85 | 197 |
| 90 | 210 |
