Troubleshooting
Tube won't hold air after installation
Ensure the tube is not pinched between the tire and rim. Check for small tears or punctures along the tube. Verify the valve is properly seated and not damaged.
Difficulty installing tire onto rim
Ensure the tube is only slightly inflated. Work the tire bead onto the rim gradually, starting opposite the valve. Use tire levers carefully if necessary, avoiding pinching the tube.
Valve stem leaks air
Check if the valve core is tightened properly. If the valve itself is damaged, the tube will need to be replaced.
