What are the steps for tire disassembly and assembly?

Tire disassembly and assembly steps are as follows: 1. Identify the front and back sides of the tire. The tire sidewall usually indicates 'Aoutside' or the tire date faces outward. 2. Apply a small amount of special tire lubricant to the bead area on both sides of the tire, then place the tire diagonally into the rim. 3. Fit the tire onto the wheel rim, paying attention to the position of the valve stem. Avoid damaging the valve stem and then straighten the tire. 4. First, assemble the back side of the tire. 5. Pay attention to the tire inflation pressure, which is usually marked on the inside of the fuel tank cap or the driver's side B-pillar as the standard pressure. 6. After completing all assembly steps, use spray foam water to check for any air leaks in the tire. 7. When assembling the vehicle, pay attention to the tightening torque of the nuts. The tightening torque varies depending on the vehicle model, generally ranging from 110-130 Nm for wheel tire screws. It is worth noting that to ensure driving safety, it is recommended to inflate with some inert gas, such as nitrogen.
The process of removing and installing tires is actually quite interesting. First, find a flat spot to park and engage the handbrake for safety. I usually check my tools first, including a jack, pry bar, wrench, and lug wrench. When loosening the wheel nuts, only loosen them about one turn—don't remove them completely yet. Then, use the jack to lift the car, making sure to position it at the frame point or recommended spot; otherwise, the car might become unstable. Once the car is raised enough for the tire to clear the ground, fully remove the nuts and take off the old tire. When installing the new tire, align it with the wheel hub holes and hand-tighten the nuts first—don’t fully tighten them with the wrench yet. Carefully lower the car, then use a torque wrench to tighten the nuts to the specified torque in a crisscross pattern to ensure even pressure. After installation, don’t forget to check the tire pressure and perform a wheel balance, or else the car might vibrate while driving. The whole process isn’t too difficult, but you need to stay focused at every step to prevent the car from slipping or parts from getting damaged. I once saw a friend who didn’t secure the car properly, and the tools flew off—it was quite a scare.
