Understanding tire specifications, especially load capacity, is crucial for vehicle safety and performance. This article from Xe Tải Mỹ Đình will explain the tire load index chart in detail, helping you quickly and accurately find the information you need.
What is the Load Index on a Tire?
The Load Index is a numerical code indicating the maximum weight a tire can carry at a specific speed (defined by the Speed Rating) under standard operating conditions specified by the manufacturer. The higher the index, the greater the load-bearing capacity of the tire. Truck and commercial vehicle tires typically have higher load indices than passenger car tires due to the demands of hauling heavy loads.
Tire Load Index Chart
Below is a detailed tire load index chart to help you easily look up the load capacity corresponding to each index:
| Load Index | Kg | Load Index | Kg | Load Index | Kg |
|---|---|---|---|---|---|
| 51 | 195 | 101 | 825 | 151 | 3450 |
| 52 | 200 | 102 | 850 | 152 | 3550 |

What is the Speed Rating on a Tire?
The Speed Rating indicates the maximum speed a tire can sustain while carrying the permitted load (defined by the Load Index) under standard operating conditions. This rating is represented by letters, from A to Z, corresponding to speeds from 5 km/h to over 300 km/h. Tires with a high speed rating ensure stable handling, good road grip, and effective braking at high speeds.
