Foam tire inserts have become more popular over the last year, with new systems introduced from Cush Core, Huck Norris, and Flat Tire Defender. After all this time we are still trying to figure out how to keep air in a bicycle tire. All tires and rims certainly have their advantages and disadvantages in terms of stability, impact resistance, durability, and strength. The Flat Tire Defender tire insert is designed to get the most performance out of your tires touching the ground.
The biggest advantage to running the FTD system is square edge impact protection. The airless foam inserts help absorb the shock and vibration of rough terrain, which minimizes tire and rim damage, and gives your bike a more forgiving feel. Using a high-density foam rubber polymer that is both resilient and light weight, the full kit keeps your sled feeling nimble and reliable while offering an extra layer of protection.
