Usually driving on the road, it is inevitable that there will be some small faults, in case of a flat tire on the road, what to do? Do you know how to properly change the spare tire? Today specially summarized the steps of the correct replacement of spare tires for friends, I hope that novice friends can learn the correct tire replacement posture, in case of emergency 1: pull over to the side to stop on a safe and flat road, pull the handbrake to open the double flash To park the car to a safe and flat place, turn off, pull the handbrake, turn on the double flashing lights, if the tire is blown at high speed, try to use the tire with only a little support to drive the car to the emergency lane. Automatic gear models: hanging P gear, pulling handbrake, manual transmission model: hanging 1st gear or reverse gear, pulling handbrake. For manual transmission models, if the engine is only hung to neutral after the engine is turned off, then the vehicle only relies on handbrake to brake. The handbrake braking force only acts on the rear wheel, if the rear wheel is replaced at this time, there is a hidden danger of slipping after lifting the rear wheel. 2: Put the triangle warning sign behind the car The warning triangle sign is placed within the safe distance behind the car (very important), and the general highway should be placed at a distance of 150 meters behind the car, that is, the distance you walk 250 steps, the ordinary highway is not less than 50 meters, that is, you walk about 80 steps. 3: Remove the spare tire and tire changing tools Usually the spare tire and tire changing tools are under the cushion of the trunk, mainly including socket wrenches, jacks and connecting rods. 4: Remove the bolt cover, loosen the bolts one by one First use the wire hook to remove the plastic cover on the top of the 5 bolts of the tire, very simple, the hook will come out as soon as it is pulled, and then use the socket wrench to unclockwise tighten the bolt. When loosening these bolts, a diagonal approach is used to prevent the fasteners from being deformed due to uneven forces. 5: Lift the car with a jack Before lifting, plug the spare tire under this car, so that in case of an accident, the car can also have a spare tire cushion when it falls, which can block it and reduce the damage. There are indicator positions of jacks on both sides of the tire, which is easy to find, and then align the jack with the position of the chassis support block, perform the lifting work, and lift it smoothly to a distance of 2 cm from the ground from the tire. 6: Remove the broken tire and put it under the car Remove all the bolts on the wheel hub, and then remove the broken tire, where the broken tire will also be removed and placed under the car. 7: Install the spare tire Install the spare tire, screw all the bolts by hand, here by hand screw to the screw can not move, because the tire is still dangling, with a wrench is not easy to screw, can not force. 8: Lower the jack to tighten the bolt After installing the bolt, you can lower the body, and then use the wrench to tighten all the bolts, and the bolt is also twisted diagonally in turn, so that the fastener can be forced more evenly and avoid tire tilt. 9: Take back the items back in place After changing the tire, you must put all the tools back in place, replace the broken tires to the original spare tire position, and do not forget that there is a warning triangle behind the car
