How Long Does It Take to Change Car Tires?
1 Answers
In a professional repair shop or 4S store, replacing all four tires takes about an hour. If you change the tires yourself, it takes approximately 20 minutes per tire. Most car owners should replace their tires within 30,000 to 50,000 kilometers, while those who drive less frequently will replace their tires periodically a few years after installing new ones. More details are as follows: 1. Tires are made of rubber, which gradually ages when exposed to direct sunlight. This is mainly because ultraviolet rays in sunlight can break and cross-link rubber molecular chains. The heat absorbed by tires from sunlight causes sulfur and raw rubber to separate. Since cars cannot avoid sunlight exposure while driving or parked outdoors, rubber has an aging cycle of about 5 years. Tires older than 5 years will harden, crack, and become brittle, at which point replacement should be considered. 2. Tire treads wearing out is common among car owners who drive frequently. Although the replacement time frame hasn't been reached, frequent use accelerates tire wear, necessitating replacement. Each tire has wear indicator symbols that serve as a reference for tread wear. When the outer tread wear approaches the height of these indicators, the tire should be replaced as it has reached its wear limit.
