Highways are undoubtedly highways that can be driven quickly, but they also have certain drawbacks, such as being deserted and often unable to receive timely assistance in case of unexpected situations. This can be said to be deeply experienced by people who encounter tire blowouts on highways. But if you have a screw jack in your trunk, it's a different story. Because a jack can help you quickly replace tires.

Below we will provide a detailed introduction to the steps for replacing tires on highways:

1. Whether it's a tire blowout or other malfunction, use all remaining support to park the vehicle on the emergency widened lane on the roadside, turn on the car's double flash, and place a triangular warning sign about 250 steps behind the rear of the vehicle to remind rear and surrounding vehicles to avoid in a timely manner;

2. Turning off the vehicle is a very important step to avoid the possibility of skidding;

3. Remove the spare tire and tire changing tool from the trunk, which must include a screw jack, wrench, and connecting rod;

4. Place the jack at the bottom of the car chassis, use the jack to lift the vehicle to a certain height, usually about 2 centimeters, and then promptly insert the spare tire under the car;

5. Remove all the bolts on the wheel hub, take out the damaged tire, place it aside, install the bolts, and then use a wrench to tighten all the bolts diagonally, which can achieve a more uniform force distribution on the fasteners.

6. After replacing the tire, don't forget the nearby warning triangle, broken tires, screw jacks, and other tire replacement tools.
