Troubleshooting
Inner tube won't hold air after installation
Check for pinch flats between the tire and rim, ensure the valve stem is straight, and verify the tire bead is properly seated.
Tire feels soft after a short period
Butyl tubes can lose a small amount of air over time; check and reinflate as needed. If significant air loss occurs, inspect for punctures or valve leaks.
Valve stem is difficult to inflate
Ensure the valve cap is removed and the valve core is functioning correctly. Make sure the pump head is securely attached.
