What does 93h on a tire mean?
2 Answers
Tire 93h indicates the load index and speed rating of the tire. Here, 93 means that the maximum weight a single tire can bear is 650KG, and h means that the maximum speed the tire can withstand is 210km/h. Tires are one of the most important components of a vehicle, and their main functions include: 1. Supporting the entire weight of the vehicle and bearing the load of the car; 2. Transmitting traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impact forces during driving, preventing car components from experiencing severe vibrations and premature damage; 4. Adapting to the high-speed performance of the vehicle and reducing noise during driving, ensuring driving safety, handling stability, comfort, and fuel economy.
I've been driving my new car for over a year now, and 93H is quite common on tires. The 93 refers to the tire's load capacity, with each tire able to bear approximately 650 kilograms, equivalent to seating four adults without causing damage. The H stands for the speed rating, supporting a maximum speed of 210 kilometers per hour, so you don't have to worry about accidents even when speeding on the highway. As a daily commuter, I pay attention to these markings because exceeding the load limit can cause the tire to leak or deform, and surpassing the speed rating can lead to blowouts and accidents. When selecting new tires, it's important to refer to the owner's manual for recommended values to ensure they match your sedan's needs. Don't compromise safety to save money by choosing the wrong index. Regular inspections and tire balancing can extend their lifespan—safety always comes first.
