2. Push the jack to the corresponding position of the car (different brands of cars have different positions, please refer to the on-board instructions). After the tire leaves the ground, knock it around with a hammer to loosen it (someone uses a pedal), and then pull the tire out of the bolt.
3. Insert the replacement tire into the bolt and screw on all the nuts (because the tire is suspended, it is difficult to tighten, so it can be tightened with a sleeve). Exit the jack and the tire will land.
4. Use a special wrench with torque adjustment (tightening force) and refer to the instructions on the vehicle to adjust it to the corresponding torque value (that is, the tightening force of the nut).
5. Tighten the nut diagonally according to the clock: 12? 6、 10? 4、8? 2. (Some tires have five nuts, which are also tightened diagonally. Remember not to tighten them in sequence. ). Tire replacement is completed.
Note: Because there is no special torque wrench, some people have to use the sleeve, step on the handle of the sleeve with their feet and finally tighten the nut. This method is not desirable, if the nut is too loose, it will fall off during driving; Stepping too hard with your foot will damage the bolt. The torque value specified in the manufacturer's guide is the safest.
