Where to Position the Jack When Changing Front Tires on a Sedan?
2 Answers
When changing front tires on a sedan, the jack should be positioned on the raised section of the side rail near the tire. Precautions for tire replacement include: 1. Identifying the correct side of the tire; 2. Selecting a quality-certified tire; 3. Replacing the valve stem simultaneously; 4. Determining the installation direction; 5. Installing new tires on the rear axle; 6. Avoiding hard braking immediately after tire replacement; 7. Loosening the lug nuts in a diagonal pattern when removing the tire; 8. Performing a wheel alignment after tire replacement. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting vehicle load; 3. Absorbing and reducing vibrations and impacts during driving to prevent damage to automotive components from severe shocks.
Last time I helped a friend change tires, I remember clearly that the jack placement under the sedan is crucial. It's mainly near the front wheel under the side skirts of the car body, where there are usually metal protrusions or marked points. Don't just place it on plastic parts, as it can easily scratch the chassis or make the vehicle unstable. Before operating, always turn off the engine and engage the handbrake, then place wheel chocks behind the rear wheels for stability. The ground should be flat and firm, with concrete being the safest. If you don't have a manual for reference, use a flashlight to locate the reinforced steel beam sections, avoiding fuel lines and suspension components. I've seen someone place the jack in the wrong spot and dent the rocker panel, costing hundreds to repair—totally not worth it. Safety first; it's better to have a secondary support stand just in case the jack fails. Also, make sure all bolts are tightened before driving.
