I agree with Tom, seems extraordinary. After some research, I found two causes to the belt separation failure
1) Internal defect in the tire carcase, these appear randomly and seem to be relatively rare. There is nothing we can do to protect ourselves from these.
2) Running low air pressure relative to the carried load. This causes the flexure of the tire at the road contact area to be great enough to exceed the "give" built into the rubber between the belt and the carcase. Why this failure is happening to folks here who pay attention to their pressures frankly mystifies me. Monitoring air pressure is vital to preventing this failure, otherwise it's just bad luck.
If anyone knows someone at a bus company it would be nice to understand their experience. I can't believe they experience our failure rate, why the difference?
