Any hardcore off-road enthusiast knows the numerous benefits that lower tire pressures offer such as improved ride quality and a larger contact patch for increased traction. However, low pressures also increase the risk of de-beading the tire during extreme side loads or aggressive driving.
The ICON Alloys Hammer PRO with patented InnerLock technology offers the best of both worlds by using a robust bead retention system to keep the tire bead secured to the wheel while also being fully DOT compliant. This provides confidence in knowing that your wheels are prepared to tackle whatever situation you encounter - on or off the beaten path. InnerLock is ready for any type of terrain and every single adventure.
