🛠️ Installation & User Guide

1. Preparation: Deflate your tire and remove the inner tube completely.

2. Placement: Unroll the liner inside the tire casing. Ensure it is centered flat against the tread area.

3. Trimming: If the liner is too long, trim the excess, leaving a 2-3 inch overlap.

4. Reassemble: Carefully re-insert the tube. Inflate partially to check alignment before reaching full PSI.

💡 Pro Tip: Ensure the liner is centered to prevent tube pinching and to provide full protection against punctures.
