When changing a tire, the jack should be placed under the chassis. Here is some information about changing car tires: 1. Function of tires: Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling contact with the ground. They are usually installed on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. 2. Replacement principles: Tires of different specifications have different inflated outer diameters and section widths. If installed on the same axle, the load distribution will be uneven. Due to the different structures of radial tires and bias tires, their cushioning performance and circumferential deformation vary. Mixing these two types of tires on the same axle will inevitably result in uneven load distribution and inconsistent wear.

When changing a tire, the jack must be placed on the designated lifting points of the vehicle's chassis. These are usually reinforced metal sections under the car, typically near the wheels. If you crouch down and look, you might notice raised areas or markings there. I remember the first time I changed a tire—I was so nervous that I placed the jack in the wrong spot, causing the car to tilt and nearly leading to an accident! Since then, I always check the owner's manual or the small stickers on the door frame to confirm the correct position. Never place the jack on plastic parts or fragile areas, as it could slip, making the tire change difficult and potentially damaging the car. Safety comes first—it's best to park on level ground, engage the parking brake, and use wheel chocks to prevent rolling. With more practice, the task becomes much simpler, but beginners should be patient.

Find the correct jacking points, which are the sturdy support points under the car, near each wheel. As a seasoned driver with decades of tire changes, I can tell you the key points are simple: avoid improper spots like near the fuel tank or thin body panels, as they can't bear the weight. Let me be straight – always check the manual or body markings before using the jack to avoid trouble. Oh, and ensuring the ground is level is crucial, otherwise the jack won't be stable and tire removal becomes difficult. Also, double-check that all screws are loosened before lifting, and raise the car to a moderate height to prevent tipping. The whole process should be quick, precise, and steady – with practice, you can finish in five minutes, making it efficient and safe.

The car jack should be placed on the dedicated lifting points of the chassis. These are reinforced areas designed by engineers to bear the vehicle's weight without deformation. I love studying car structures - such points are usually located on the inner side of wheel arches or steel beams, and you can find the markings by using your phone's flashlight. Placing the jack incorrectly, such as on suspension components, may cause the jack to crush oil pipes or damage the car body, increasing repair costs. Remember to park the car steadily in P gear and turn on hazard lights during operation. Simply put, familiarize yourself with your vehicle's lifting points and regularly check the user manual during routine maintenance to prevent minor issues from becoming major faults.
