How Are Tire Separation Cases Caused By Manufacturing Defects?

by Terry Bryant

Tire separation cases are the most common form of wheel failure, and they often result in tragic outcomes. To an extent, they are inevitable, as rubber and steel do not adhere together easily. However, poor manufacturing practices make tire failure much more likely. Manufacturers push their workers to the limit, sometimes requiring them to work 12-hour shifts that result in severe fatigue. And with lax quality controls, it’s no surprise that tire failures are a problem throughout the industry.

Tire failure is more likely in hot and humid climates, and more likely when the wheel is underinflated, though often when there are manufacturing defects already present. Rubber and steel do not readily bond to each other, either. This means that manufacturers should do everything possible to avoid tire separation cases, and they often don’t.

For example, manufacturers may not execute the curing process properly, or may rely on rubber stock that is beyond its useful life. Manufacturers may employ petroleum solvents during the curing process, and this may effect how the rubber bonds. Foreign material may be cured in with the tire as well, and investigators have found everything from chicken bones to shotgun shells in defective tires. Improper repairs may fail to adequately deal with tread damage, making failure even more likely.

These careless manufacturing processes can be prevented, and as a result, they will help prevent catastrophic tire failure as well. Vehicle owners should expect that level of scrutiny from the companies they trust with their safety.
