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.

From my perspective, changing a tire can take varying amounts of time depending on several factors. For instance, at a shop, a professional can handle it alone and finish in 15-25 minutes with advanced tools and familiar procedures. However, if you're doing it yourself (DIY), it depends on whether you have the proper jack and wrench. The size of the tire also matters—SUV tires are heavier and more challenging than those of smaller cars, potentially adding 5 to 10 minutes. In the case of a roadside flat, safety is paramount: set up warning signs before starting, and don't take unnecessary risks. For regular practice, an average of 20 minutes per tire is realistic, but if the tire is old or the bolts are rusted, you might need lubricant, which could extend the process to half an hour. Overall, being well-prepared shortens the time, but safety should always come first—never cut corners.

When changing tires, I always remind myself: the time varies depending on the person and tools. A beginner might take 30-40 minutes for the first time, while an experienced person can do it in just 15 minutes. The key is to park the car securely, quickly loosen the screws with the right tools, lift the car to replace the spare tire, and check after tightening. Don't underestimate these steps—panic can easily prolong the process. It's advisable to watch instructional videos beforehand.
