The Air - Liner is an amazing reusable foam insert for tubeless tires. It offers top - notch rim protection, significantly boosts grip, and effectively prevents punctures. With outstanding bump compliance, it ensures the bead stays locked even at lower tire pressures. In case of air loss, this insert allows for run - flat use.

Using the Air - Liner is easy. First, make sure your tubeless tire is clean and ready. Then, insert the foam insert carefully into the tire. It's designed to fit well, so just take your time to place it correctly. When it comes to pressure, you can use lower pressures than usual because the insert helps keep the bead locked. For normal use, this insert is great, but if you notice any signs of wear or damage, it's a good idea to check it. If you get a puncture, the insert allows you to keep riding for a while. As for maintenance, simply clean it with a mild soap and water when it gets dirty. Avoid using harsh chemicals as they might damage the foam. With proper use and care, your Air - Liner insert will serve you well for a long time.
