In the October 2000 issue of the Tire Retreading/Repair Journal, then-Editor Marvin Bozarth published a photo (below) that he said ``clearly illustrates the damage a zipper rupture can cause.''
Mr. Bozarth, at the time executive director of the International Tire & Rubber Association, noted that in the case illustrated, an 11R22.5 truck tire ruptured in a safety cage during inflation. ``It blew a 20-inch hole in the 3/4-inch plywood wall protector and dislodged the metal panel from the outside of the building,'' he wrote.
The unnamed dealership where the incident took place ``has a strict policy in place for tire mounting and inflation procedures,'' Mr. Bozarth continued. ``As a result, they have not experienced any personnel injuries even though a significant number of zipper ruptures have occurred.''
