1. Confirm whether the specifications of the inner tube match the outer tire. When installing the inner tube, carefully check for sand particles, cracks, or other debris inside the outer tire. 2. Inspect the steel rim carefully during installation and ensure it has no defects such as deformation, burrs, or foreign objects. 3. When installing the tire, always place the lug tape on the rim first to prevent puncturing the inner tube. 4. Before inflating the inner tube, ensure it is not pinched between the rim and the tire bead. Inflate strictly according to the tire’s recommended air pressure to avoid underinflation or overinflation. 5. After installation, check the valve for air leakage and secure the valve core with the rubber cap.
