What is the Tire Load Index Chart?
2 Answers
Tire load index chart is: 1. Load index 91, corresponding to the maximum load of 615kg, with an allowable maximum speed of 240 kilometers per hour; 2. Load index 92, corresponding to the maximum load of 630kg, with an allowable maximum speed of 210 kilometers per hour; 3. Load index 97, corresponding to the maximum load of 730kg, with an allowable maximum speed of 300 kilometers per hour. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb the vibrations and impact forces during driving, preventing severe vibrations and early damage to car components; 4. To adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
I usually enjoy studying cars, and the tire load index chart is an essential reference. It's essentially a chart that lists the maximum load capacity represented by different numerical codes. Each number corresponds to a weight value; for example, 85 stands for approximately 545 kg, while 90 represents around 600 kg. This chart can typically be found on the sidewall of the tire or in the owner's manual, and its purpose is to ensure that the tires you install can handle the vehicle's weight, preventing overloading, blowouts, or damage to the suspension system. When selecting new tires, checking this chart is crucial—don’t just focus on the size; the load index must also match. Otherwise, safety at high speeds can be significantly compromised. I often remind my friends to check this before road trips, especially when the car is fully loaded with luggage. Different vehicle brands have varying load requirements, and this chart helps you make precise selections, improving driving stability.
