Big Rig Tire Blowout Sends Semi Rolling, Seriously Injures Motorcyclist in Missouri
A weekend ride turned into a nightmare after a tractor-trailer suffered a tire blowout on Interstate 44 in Pulaski County, Missouri.
According to the Missouri State Highway Patrol, the semi experienced a tire failure while traveling down the interstate. The driver lost control, sending the truck into the median where it rolled over and caught fire. The truck driver suffered minor injuries.
The real tragedy came seconds later.
Flying debris from the crash struck two motorcycles traveling nearby. One rider, a man from South Milwaukee, Wisconsin, was seriously injured and had to be airlifted to a Springfield hospital.
Tire Blowouts Are More Dangerous Than Most Riders Realize
Most riders have seen the shredded strips of truck tire scattered along highways. Truckers call them “road gators,” but those chunks of steel-belted rubber are anything but harmless.
Federal crash studies have found that tire failures are responsible for roughly 8,000 to 11,000 commercial truck crashes each year, accounting for about 6% of serious large truck crashes. Blowouts can lead to rollovers, jackknifes, flying debris, and multi-vehicle crashes.
Are Retread Tires to Blame?
Retread tires often get blamed whenever a truck tire comes apart, but the reality is more complicated.
The trucking industry uses retread tires extensively because they’re significantly less expensive than brand-new tires and, when properly maintained, can perform safely. Investigations have shown that poor maintenance, underinflation, overloading, impact damage, and excessive heat are much more common causes of tire failures than the retreading process itself. However, some safety research has found that retread tires are more susceptible to failure at sustained high speeds, especially if they aren’t properly maintained.
In many cases, the strips of tread found on highways are actually the tread separating from an otherwise intact tire—not necessarily proof the tire itself was a retread.
Why Motorcyclists Face Greater Risk
For someone in a car, flying tire debris is frightening.
For a rider, it can be deadly.
A chunk of truck tire can weigh several pounds and may be launched into traffic at interstate speeds. Even if it doesn’t hit the rider directly, swerving to avoid debris can quickly lead to a loss of control.
Motorcyclists should remember:
- Avoid riding beside a semi for extended periods.
- Leave extra following distance so you have time to react.
- Watch truck tires for signs of damage, wobbling, or pieces of tread beginning to separate.
- Never assume shredded tire debris lying in the road is harmless—it can be slippery, hide other hazards, or send a motorcycle off balance.
Those Tire Treads on the Highway Aren’t Just Litter
Discarded truck tire tread creates hazards long after the original blowout.
The heavy rubber can:
- Cause motorcycles to lose traction.
- Force riders into sudden evasive maneuvers.
- Damage vehicles that strike them.
- Trigger chain-reaction crashes when drivers swerve unexpectedly.
For riders, even a small piece of tread can become a serious obstacle at highway speed.
The Bottom Line
This Missouri crash is another reminder that sharing the road with commercial trucks requires extra awareness. Tire failures happen in an instant, and when an 80,000-pound truck loses a tire at highway speed, everyone nearby is at risk.
Giving big rigs plenty of space, staying out of their blind spots, and watching the road well ahead for debris can give riders the precious seconds they need to avoid becoming part of the next headline.
