How Long Does It Take to Change Car Tires?
2 Answers
Replacing all four tires at a professional repair shop or 4S store takes about one hour. If you change the tires yourself, it takes approximately 20 minutes per tire. Car owners should replace their tires every 30,000 to 50,000 kilometers. For those who drive less frequently, tires should be replaced periodically a few years after installation. Below is relevant information: 1. Tires are made of rubber, which gradually ages under direct sunlight. This is mainly because ultraviolet rays in sunlight can break and cross-link rubber molecular chains, while the heat absorbed by tires causes sulfur and raw rubber to separate. Driving or parking outdoors inevitably exposes tires to sunlight. 2. The aging cycle of rubber is about five years. Tires older than five years harden, crack, and become brittle, at which point replacement should be considered. 3. Worn-out treads—this occurs among frequent drivers. Although the tires may not have reached the recommended replacement age, heavy usage accelerates wear, necessitating replacement.
I enjoy working on my car myself, and changing tires is something I do often. The first time I did it, I was extremely nervous and it took me nearly an hour, fumbling around mostly because I couldn't find the right tools. Now that I'm more experienced, I can usually finish changing a tire within 20 minutes, provided I have everything prepared in advance: park on a flat and safe spot, engage the handbrake, and use the jack and wrench to loosen the lug nuts first. If the tire is flat on the road, you'll also need to retrieve the spare tire and replace it—the whole process should be done steadily to avoid accidents caused by rushing. With more practice, you'll get faster, and if you have all the tools ready, you might even finish in 15 minutes. For beginners, it might take over 30 minutes, so it's advisable to bring a friend along for help to make it safer and more efficient.
