2 Answers
Precautions for changing tires are: 1. Identify the front and back sides of the tire; 2. Choose qualified tires; 3. Replace the valve stem simultaneously; 4. Determine the installation direction; 5. Install new tires on the rear axle of the vehicle; 6. Avoid sudden braking after replacing new tires; 7. Remove screws diagonally when removing the tire; 8. Perform a four-wheel alignment when changing tires. The functions of tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components.
I found safety is the top priority before changing a tire. Last time when I had a tire blowout on the highway, my first reaction was to turn on the hazard lights and pull over to the emergency lane, then get out to place a 150-meter warning sign - I even used a toolbox when the triangle reflector wasn't enough. After confirming the vehicle was stable, I engaged the parking brake, shifted to P gear, and used wooden blocks to chock the diagonal wheels to prevent rolling during jacking. Always check if the spare tire is expired - some vehicle spare tires age and crack after just five years. If changing tires at night, wearing a reflective vest is mandatory, as there might be snakes in the grass beyond highway guardrails - I got scared once by this. These preparations may seem tedious, but they can save lives.
