The Air-Liner is an outstanding foam-based, reusable insert for tubeless tires. It's like a tire's best friend, protecting the rim, boosting grip, and warding off punctures. This system offers amazing bump compliance and keeps the bead locked even at lower pressures. And if you lose air, the insert allows for run-flat use. Features include its small size and suitability for 1.90 - 2.25' tires.

To use the Air - liner MTB Tire Insert, first make sure your tubeless tire is clean. Then, carefully place the insert inside the tire. It's easy to fit, just take your time. When it comes to inflation, you can go for lower pressures as the insert helps with bead lock. Remember, if you experience air loss, you can still keep going for a while because of the run - flat design. For maintenance, check the insert regularly for any signs of wear. If it gets dirty, you can wash it gently with mild soap and water. Store it in a cool, dry place when not in use.
