THESE TIRES MAY NOT HAVE ADEQUATE RUBBER COVERAGE OF THE BELT EDGE DUE TO LOW TREAD GAUGE IN THE SHOULDER SLOT AREA OF THE TIRE. WHEN THIS CONDITION EXISTS, IT MAY EVENTUALLY CAUSE CRACKING AT THE BASE OF THE SHOULDER SLOTS RESULTING IN EXPOSED BELT WIRE WHICH COULD LEAD TO ACCELERATED BELT DEGRADATION, WHICH COULD RESULT IN A SEPARATION. IF THE SEPARATION IS NOT DETECTED, CONTINUED USE MAY CAUSE THE PLY CORDS TO BREAK AND THE TUBELESS LINER TO TEAR AND LOSE THE INFLATING AIR.
