What's wrong, in plain English
The tires on these vehicles were left in the curing process for too long during manufacturing. Tires that are cured too long can develop a break in the sidewall, which can cause sudden air loss, or the tire's belt edge can separate, causing the tread or belt to come apart. Either problem can cause the driver to lose control of the vehicle.
