Using Tannus Armour is easy. Just place it between your bike tire and inner tube. When you're installing, make sure it's properly aligned and flat to get the best protection. As for usage, it works great on various terrains like city roads, off - road trails, and gravel paths. There aren't many special precautions, but be careful when handling sharp tools near the tire to avoid accidentally damaging the liner. For maintenance, simply check it regularly for any signs of wear or damage. If you notice any cuts or tears, it might be time to replace it. Keeping it clean can also help it last longer. Just wipe it down with a damp cloth if it gets dirty.
