2. Apply soapy water to the tire bead. This will help to seal the tire bead to the rim and prevent air from leaking out.
3. Use a high-pressure air compressor to inflate the tire. You will need to use a high-pressure air compressor to inflate the tire to the recommended pressure.
4. Reinstall the valve stem core. Once the tire is inflated to the recommended pressure, you can reinstall the valve stem core.
5. Check for leaks. Use soapy water to check for any leaks around the tire bead and the valve stem core. If you see any leaks, you can try to tighten the valve stem core or reapply the soapy water.
If you are unable to inflate the tire, you may need to take it to a tire shop for professional repair.
