What does the tire specification 245/50r20 mean?
1 Answers
245/50r20 is the tire size specification, indicating that the tire's section width is 245 millimeters, the aspect ratio is 50, 'r' stands for radial tire, and 20 means it can be mounted on a 20-inch rim. The tire maintenance methods are as follows: 1. Inspection: Pay special attention to the condition of the tires, checking for any debris or foreign objects lodged in them. If found, remove them promptly. If not removed in time, some may fall off during driving, while others may gradually 'erode' the tire, penetrating deeper over time. When this reaches a certain point, they can puncture the tire, leading to blowouts or leaks, which can be dangerous. 2. Timely replacement: During inspection, if the tire valve is made of rubber and turns dark red, it indicates that the valve has aged and can no longer ensure good airtightness. It is best to replace it. 3. Check wheel balance: During driving, the tires may experience impacts, high-speed driving, sharp turns, emergency braking, or crossing obstacles, which can cause the tires to lose balance. This can result in vehicle pulling, bumpiness, or uneven tire wear (commonly known as 'tire cupping'), affecting driving safety. 4. Check tire pressure: Monitoring tire pressure is the most important aspect of daily tire maintenance. It is good practice to develop a habit of checking tire pressure regularly (preferably once a week) to eliminate potential hazards early. Tire pressure should be checked when the tires are cold, as driving heats up the tires, causing the pressure to read higher than the actual value. If you reduce the pressure of a hot tire, it will be insufficient once cooled.
