How to Replace the Spare Tire on a Car?

Steps to replace the spare tire on a car: 1. The car owner needs to remove the damaged tire by loosening the screws with a wrench, but be sure not to remove them completely—just loosen them; 2. Use a jack to lift the car, ensuring the jack is positioned correctly and not lifted too high—just enough to remove the tire; 3. Align the spare tire with the screw holes and secure it, making sure the screws are tightened. In daily life, since the spare tire may not be used for a long time, the car owner should maintain and inspect the spare tire regularly. After replacing the spare tire, it should not be used for an extended period, even if it is a full-size spare tire. This is because long-term use of a spare tire with significantly different parameters can affect the car's braking system, steering system, and suspension, potentially leading to safety issues.
I've changed spare tires quite a few times. The general procedure is to find a flat and safe spot to park, shift to P gear, engage the parking brake, and turn on hazard warning lights. Don't rush to use the jack immediately - first take out the warning triangle and place it about 100 meters behind the car to protect yourself and others. Then use the wrench from the toolkit to slightly loosen the lug nuts (remember - loosen, not fully remove). Next, position the jack at the proper chassis point (avoid wrong spots like near the fuel tank) and lift the car. After the wheel is off the ground, completely remove the damaged wheel, take out the spare tire and mount it, then hand-tighten the nuts for initial fixation. Lower the jack to let the car touch the ground, then fully tighten the nuts diagonally with the wrench - don't miss this step. Finally, check the spare tire pressure (not too high or low), and remember not to exceed 80 km/h with a temporary spare. This job seems simple but safety is crucial - spare tires need regular checks to avoid aging from long-term disuse. I've seen people in such a hurry that they didn't tighten properly, leading to wheels flying off while driving - extremely dangerous. So patience is key, perform every step steadily.
