What is the basic introduction to car tire knowledge?
2 Answers
Tire knowledge introduction is as follows: 1. Tire classification: Can be divided into radial tires and bias tires. 2. Tread classification: Can be divided into rib tread tires, transverse tread tires, mixed tread tires, and off-road tread tires. 3. Type classification: Tires can be roughly classified into 8 types by vehicle type. Namely: PC - Passenger car tires; LT - Light truck tires; TB - Truck and bus tires; AG - Agricultural vehicle tires; OTR - Off-the-road tires; ID - Industrial vehicle tires; AC - Aircraft tires; MC - Motorcycle tires. 4. Size classification: 1) Full-size spare tire: The specifications of a full-size spare tire are exactly the same as the other 4 tires on the vehicle, and it can replace any temporarily or permanently unusable tire. 2) Non-full-size spare tire: The diameter and width of this spare tire are slightly smaller than the other 4 tires, so it can only be used as a temporary replacement, and only for non-driving wheels, with a maximum speed not exceeding 80km/h.
Car tires are the only part of the vehicle that comes into contact with the ground, directly affecting safety and handling. After driving for so long, I've learned that basic knowledge includes tire structure—the tread provides friction, the sidewall protects the tire from damage, and inner tubes are rare in modern tires, as most are tubeless now. Sizes like 205/55R16 represent width, aspect ratio, and rim diameter. When choosing tires, consider the season: summer tires have shallow treads for dry roads, while winter tires have deep treads for anti-slip performance. Maintenance is crucial—check tire pressure at least once a month, as underinflation increases fuel consumption and the risk of blowouts. Wear indicators are located in the tread grooves; once they're flush, it's time to replace the tires. My personal recommendation is to replace them every two years or 40,000 kilometers to ensure safe driving. Don’t skimp on this—one accident could cost far more.
