HAD A FLAT TIRE AND FOUND A 3" SLIT OF DRY ROT AND WHEN STORE INSP. MY TIRES, THREE WERE DRY ROTTED WITH THE 4TH ON THE BORDERLINE. THIS WAS A VERY DANGEROUS SITUATION FOR MY FAMILY AND I. WE HAD JUST BEEN ON THE INTERSTATE DOING 65 MPH WITH THESE TIRES. HOW MANY MORE FAMILIES ARE RIDING ON THESE TYPE OF TIRES?
