1. Confirm whether the specifications of the inner tube match the outer tire. When installing the inner tube into the outer tire, carefully check for sand particles, cracks, or other debris inside the outer tire that could cause damage. 2. Carefully inspect the steel rim during installation to ensure there are no defects such as deformation, burrs, or foreign objects. 3. When installing the tire, always place the lug tape on the steel rim first to prevent the inner tube from being punctured. 4. Before inflating the inner tube, ensure it is not pinched between the steel rim and the tire bead. Inflate strictly according to the tire's marked air pressure to avoid accidents caused by under-inflation or over-inflation. 5. After installation, inspect the valve stem to prevent air leakage and secure the valve core with the rubber cap.
