The fat tire insert adds a protective foam layer between the tire and inner tube. It provides 15 mm of puncture protection across the top and 2 mm of protection along the sidewalls.
Patented Aither Technology uses a multi-cell foam compound to form the insert’s protective structure. Each individual package contains 1 tire insert and 1 tube with a Schrader valve.
The variants differ by wheel-and-tire size: 20 x 3.0-4.0, 24 x 4.0, 26 x 3.0, or 26 x 4.0-4.8. The puncture protection, foam technology, package contents, and price remain the same across all 4 size options.
