2012 PALOMINO COLUMBUS Wheels Problems

WHILE DRIVING ON I-95 SOUTH NEAR EXIT 73, WE WERE PULLED OVER BY A NC HIGHWAY PATROL. THE TROOPER NOTICED SOMETHING WOBBLING UNDER MY 37' FIFTH WHEEL CAMPER. UPON INSPECTION, I FOUND A GRAPEFRUIT SIZE BUBBLE ON THE INSIDE OF THE RIGHT FRONT TRAILER TIRE. HAD I CONTINUED DRIVING, THE TIRE COULD HAVE EXPLODED WHEN THE BUBBLE POPPED. THE TIRE PRESSURES WERE CHECKED 1 HOUR EARLIER, PRIOR TO DEPARTING FOR OUR TRIP. THEY WERE ALL AT THE SPECIFIED 80 PSI.I DON'T DRIVE OVER 65 MPH AND WHEN THE TRAILER IS IN STORAGE, THE TIRES ARE COVERED TO REDUCE UV EXPOSURE AND I PARK ON A PIECE OF PLYWOOD. THE TIRES WERE INSTALLED BY COLUMBUS. THEY ARE AKURET ST235/80R16 10PLY TRAILER TIRES. THIS TIRE HAS A BUILD DATE OF 0612. *TR
