Step 1
Once you have a flat tire, slow down immediately and pull over to the side of the road. After getting out of the car, first place a safety warning sign behind the vehicle to ensure safety. The usual placement is under the storage panel in the trunk.
Step 2
Take out the spare tire and tools stored under the storage panel and get them ready. The tools include a jack, wrench, hook, etc.
Step 3
Use the wrench to loosen the four lug nuts on the flat tire by turning them counterclockwise. It’s best to do this in a crisscross pattern. Considering that women may have less strength, you can push the tire outward to make it easier to step on the wrench. Just loosen the lug nuts—don’t remove them completely.
Step 4
Place the jack under the car, insert the wrench into the adjustment screw that controls lifting, and rotate it to lift the wheel off the ground. For the front wheel, the support point is near the front part of the front door, and for the rear wheel, it’s near the back part of the rear door—you can feel it with your hand. When placing the jack, make sure it's on flat ground, with the larger base facing down and the smaller base fitting into the raised support point on the car’s chassis.
Step 5
Once the wheel is lifted, remove all the loosened lug nuts and pull the tire straight outward to take it off. If you lack strength, you can kick the upper part of the tire to help it come off—but avoid kicking the lower part to prevent the tire from suddenly falling and injuring your foot.
Step 6
Roll the spare tire into position, align the four holes on the wheel with the four screws on the axle, then lift the tire and fit it onto the screws. Push it inward, screw on the lug nuts, turning clockwise, and tighten them in a crisscross pattern. If you don’t have enough strength to lift the wheel, align it first, then lower the jack slightly to fit the nuts in before raising the jack again.
Step 7
After the spare tire is installed, remove the jack. Once the car’s tire is back on the ground, use the wrench to tighten the lug nuts securely. If you can’t tighten them by hand, you can step on the wrench as you did when removing the tire until they’re fully tightened to ensure safety. (Don’t forget to remove the warning sign before leaving!)
