What is the tutorial for replacing a car spare tire?

[RileyLee]

The tutorial for replacing a car spare tire is as follows: 1. Take out the spare tire, jack, and tire wrench from the trunk; 2. Place the jack on the chassis support, slowly lift the car body, and place the tire pad under the car; 3. Use the wrench to remove the bolts of the tire that needs to be replaced and take off the tire; 4. Align the spare tire with the axle and bolt holes, then tighten the tire bolts. A spare tire refers to the backup tire of a car, with the same specifications as the original car tire. Precautions for using a spare tire: 1. Regularly check the spare tire; 2. It should not be used for a long time; 3. The spare tire should not participate in tire rotation; 4. Avoid placing it together with oil products.

As someone who frequently drives long distances, my practical experience with changing a spare tire is: First, find a flat and safe place to park, preferably away from traffic, turn on the hazard warning lights to avoid rear-end collisions, and firmly engage the handbrake while shifting to P or N gear. Retrieve the spare tire and tools from the trunk, including the jack and wrench. The crucial step is to loosen the lug nuts counterclockwise with the wrench before lifting the car—but don't remove them completely, or the wheel may fall off. Locate the jack's support point, usually a notch on the vehicle's undercarriage beam, and slowly raise it until the tire is a few centimeters off the ground. Remove the old tire and set it aside. When installing the spare tire, align the bolt holes and hand-tighten the lug nuts for initial fixation, then tighten them in a diagonal sequence to avoid misalignment. After lowering the jack and letting the car settle, firmly tighten all lug nuts to ensure stability. Spare tires have speed limits—it's best not to exceed 80 km/h—and you should visit a repair shop as soon as possible to check the original tire and tire pressure. Common mistakes include lifting the car without loosening the lug nuts, which can be dangerous, or forgetting to limit speed, causing excessive wear on the spare tire.

My advice starts with safety: choose an open area to park, turn on hazard lights to make your car visible to others, and ensure the handbrake is fully engaged. Retrieve the toolkit and confirm that the jack, wrench, and other tools are complete. Loosen the wheel nuts about halfway—do not remove them entirely. Position the jack accurately, such as near the reinforced chassis point of the flat tire, and slowly raise it until the tire is off the ground. Remove the damaged wheel and place it safely aside, then mount the spare tire by hand-tightening the nuts in a crisscross pattern initially. Lower the jack slowly to prevent the car from tilting, and finally tighten the nuts firmly in a cross pattern. Check the spare tire’s pressure to match the recommended 80 psi as labeled, and keep driving speed between 60-80 km/h to avoid accidents. Regularly maintain spare tire tools to prevent failure in emergencies, ensuring safe and worry-free driving.

I enjoy DIY car maintenance, and mastering the spare tire replacement tools is crucial: The jack must be placed on the designated support points under the car, otherwise it may damage the chassis. Use the wrench to loosen the bolts counterclockwise, following a crisscross pattern but not removing them completely. Raise the car steadily until the wheel is just off the ground for easy operation. When removing the wheel, avoid excessive force. Align the spare tire holes and hand-tighten the bolts for initial fixation. After lowering the car, tighten the bolts diagonally with extra force, ensuring the wrench is securely engaged to prevent loosening. Regularly lubricate and inspect the tools in the spare tire kit to ensure they're ready for next use. Remember, speed limits apply when using a spare—avoid long trips to prevent accidents.
