The solutions for a damaged car tire are: 1. Replace the spare tire and drive to a repair shop for fixing; 2. Call for help and wait for rescue. The functions of a tire are: 1. Transmit driving force, braking force, and steering force to operate the car; 2. Support the vehicle load; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that may damage car components. The maintenance methods for tires are: 1. Regularly clean stones stuck in the tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect front wheel alignment; 6. Adopt careful driving habits, choose smooth road surfaces while driving, avoid objects that can puncture or scratch tires, and steer clear of chemical spills that may corrode tires.

If one of your car tires is damaged, stay calm and don’t panic. I experienced this on the highway before. Immediately turn on your hazard lights and pull over to the side. Get out and place a warning triangle 150 meters behind the car. Take out the jack and wrench from the trunk, ensure the car is stable, shift to Park (P), and engage the handbrake. When loosening the lug nuts, apply force in a diagonal sequence, then slowly lift the car body and remove the damaged tire to replace it with the spare. Remember, spare tires are usually smaller, so don’t exceed 80 km/h. Finally, tighten the lug nuts with full force, and don’t forget to head to a tire repair shop at the next exit—spare tires aren’t meant for regular use.

I'm quite familiar with changing tires, having done it seven or eight times. Always park on a flat, hard surface, otherwise the jack can easily slip. Loosen all the nuts with a wrench before lifting the car—this way, the wheel still has traction, making it easier to apply force. The jack must be aligned with the metal protrusions under the car; I've seen novices jack up the wrong spot and deform the chassis. When changing the tire, place the old tire under the car as a safety measure—it can save your life if the jack fails. Most importantly, after driving a few kilometers with the new tire, always recheck the tightness of the bolts. Metal expands and contracts with heat, which can cause the bolts to loosen.

As a female driver, I make sure to prioritize safety before changing a tire. First, I put on gloves because tires are very dirty. After turning on the hazard lights, I check that there are no cars within 100 meters behind me before getting out of the car, and I place the warning triangle in a visible location. The jack handle is particularly heavy, so I use my foot to step on it to save effort. The hardest part of changing a spare tire is loosening the lug nuts—I stand on the wrench with my full body weight, making sure the wrench fits perfectly with the nuts to avoid stripping them. Remember, spare tires have shallow treads, so drive extra carefully in rainy weather.
