How to Change a Flat Tire?
2 Answers
When removing the tire, do not immediately jack up the car. First, use the lug wrench to loosen each wheel bolt one by one. Align the spare tire with the wheel bolt holes, use your leg or foot to brace the spare tire to prevent movement, and then slightly tighten the bolts in a diagonal pattern.
A few days ago, I just helped my neighbor change a tire, and the process is actually quite simple. First, park the car on a safe and level ground, turn on the hazard lights, and place the warning triangle (50 meters away on city roads, 150 meters away on highways). Before using the jack, loosen the screws first—remember to turn them counterclockwise with a wrench but don't remove them completely. Find the correct chassis support point and lift the car until the tire is about 2 cm off the ground. Then, remove all the screws and take off the flat tire, replacing it with the spare tire and hand-tightening the screws. After lowering the car, use the wrench to tighten the screws in a diagonal order with force—I've seen people forget to tighten them and have a wheel fly off halfway! Don't drive too fast on the spare tire; the speed limit is 80 km/h, and you should head to a repair shop as soon as possible.
