What are the precautions for tire installation?

Tire installation precautions include: 1. Pay attention to installation direction and inflation. If using the original factory tires, follow the manufacturer's requirements for installation. For non-original tires, generally the side with the production date should face outward. For directional tires, the arrow on the tire should align with the vehicle's forward direction during installation; 2. During inflation, the tire can be inflated to its maximum allowable pressure first, then reduced to the standard pressure specified by the manufacturer. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. They are usually mounted on metal rims to support the vehicle body, cushion external impacts, maintain contact with the road surface, and ensure driving performance.
Before installing tires, ensure the tire size matches your vehicle – don’t just use old tires casually. The wheel hub holes must be thoroughly cleaned, as dust or rust can cause loose bolts. During installation, first jack up the car to a secure position, preferably using wheel chocks to prevent rolling. When tightening bolts or nuts, don’t rush—start by hand-tightening them diagonally, then use a torque wrench to reach the manufacturer’s recommended torque. Over-tightening can damage the wheel hub, while under-tightening is dangerous. After installation, don’t forget wheel balancing to avoid excessive steering wheel vibration while driving. Finally, check the tire pressure and inflate according to the recommended value on the door sticker—never overinflate. As a daily driver, skipping these steps is risky, as it may lead to roadside breakdowns. Regular tire replacement also extends their lifespan and reduces accident risks.
Changing tires is quite interesting; I always enjoy doing it myself. First, make sure the wheel hub surface is smooth and free of dirt, and lubricate the screws to prevent seizing. When installing, align the wheel hub holes and mount it steadily, then use a cross wrench or torque wrench to tighten the bolts diagonally one by one. It's crucial not to overlook the torque value, as different cars have different standards, generally ranging between 80 to 140 Nm. Afterward, don't forget to perform a dynamic balance test; otherwise, the car will shake uncomfortably at high speeds. Before inflating, check if the valve is leaking and adjust the pressure according to the standard. Remember, safety always comes first—place the jack at the designated points on the car frame and avoid lifting the wrong spot. Handling these small details well ensures smooth tire performance and longevity, and doing it yourself can also save on repair costs.
