What Do the Letters on Tires Mean?

[AngeloMarie]

The alphanumeric characters on tires represent the section width, aspect ratio, tire type code, rim diameter, load index, and speed rating. Here are some precautions for using car tires: 1. Bulging: If bulging occurs on a tire, it must be replaced immediately; otherwise, the risk of a blowout increases. 2. Tire lifespan: Tires are rubber products, and rubber deteriorates over time. Under normal conditions, tires installed on a car can last for four years. 3. Regularly check tire pressure: During regular use, it's important to frequently check the tire pressure. Tire pressure should not be too high or too low. If the pressure is too high, it reduces the contact area between the tire and the ground. If the tire pressure is too low, the tire may experience wave deformation during high-speed driving, increasing the risk of a blowout and potentially shortening the tire's lifespan.
