RC crawling enthusiasts, these silicone tire foams are a total game-changer for your 1.9 scale tires! Unlike traditional absorbent foam that gets waterlogged, this silicone material is completely waterproof - perfect for those creek crossings and muddy trails. The 108x42mm size is designed specifically for 1.9 scale tires on popular models like Axial SCX10, TRX4, Capra, and most other 1/10 scale crawlers. The three-layer hollow design gives you customization options - you can cut sections to make them softer for better grip, or leave them intact for firmer sidewall support. The blue and red versions are harder (ideal for 5-8kg chassis) while purple and green are softer (perfect for 2-4kg chassis). At about 82-84 grams each, they add nice weight to your tires for lower center of gravity and improved traction. The sidewall support is significantly better than standard foam, helping your tires maintain their shape during hard compressions and steep climbs. Installation is straightforward - just remove your old foam and slip these in. Whether you're competing or just trail running, these silicone inserts provide that perfect balance of deformation and rebound that serious crawlers look for in high-performance setups!
