Warranty Information

  • Flat Tire Defender has a no warranty, no replacement cost policy. All sales are final.
  • Flat Tire Defender is not responsible for damages to; tire, rim, wheel assembly, bicycle and/or related items. 
  • Flat Tire Defender is designed to use with air pressure in the tire. If air pressure is lost during a ride which is typically from; improper installation, tire bead damage, incorrect tire for terrain, tread puncture, sidewall cut, rim damage and/or incorrect tire pressure, the load is put solely on the foam inserts. Although the Flat Tire Defender provides an added layer of protection between tire sidewall and rim edge, the excessive load on the foam insert can only absorb so much of the impact when traveling over rough terrain; roots, rocks, jumps, high cornering loads, etc. The impact is then transferred directly on the wheel assembly which can result in damage to tire, rim and/or wheel assembly.
  • There are many variables related to getting a flat tire: improper installation, brand of tire, tire casing spec, tire pressure, rim material, rim design, bike/suspension set up, rider ability, etc. Contact Flat Tire Defender for more information.
