Truck Talk: Tire Blowouts and Explosions

Watch this Truck Talk segment on YouTube

A commercial truck tire blowout is not a random event. It is almost always the result of a failure in maintenance, inspection, or loading that someone was required by law to prevent. When a tire explodes on an 80,000-pound truck traveling at highway speed on I-64 or I-65, the debris and loss of vehicle control can cause catastrophic crashes in an instant. Understanding the causes, the regulations that were in place to prevent them, and who carries responsibility is essential for anyone harmed in one of these crashes.

How Common Are Tire-Related Truck Crashes

According to the NHTSA TireWise program, 646 people died in tire-related crashes in 2023. These numbers include all vehicle types, but commercial trucks account for a disproportionate share of the most severe outcomes because of their size and operating demands. Flat or leaking tires were the single most common out-of-service violation in FMCSA inspections for 2023, with nearly 99,000 orders issued, according to FMCSA enforcement data. The volume of these violations confirms this is a maintenance problem, not an unavoidable mechanical event.

What Causes Commercial Truck Tires to Blow Out

The most common causes of commercial truck tire failures fall into categories that are all traceable to specific parties:

• Underinflation: the most frequent culprit, as tires running below proper pressure build heat through flexing and can fail suddenly
• Overloading: exceeding weight limits places stress on tires beyond their rated capacity
• Worn tread: tires with inadequate tread depth are far more vulnerable to blowout from road debris
• Defective retreads: improperly retreaded tires can separate at high speed, creating large debris hazards
• Manufacturing defects: a defective tire can fail regardless of maintenance

Federal tire standards at 49 CFR Part 393.75 specify minimum tread depth, inflation requirements, and prohibit tires with exposed fabric or visible cord damage. A tire found to be in violation of these standards was already dangerous before the blowout occurred.

The Dangers of Tire Debris on Kentucky Interstates

When a large commercial truck tire fails at highway speed, the consequences come in two forms. The first is the immediate loss of vehicle control, which can cause the truck to swerve, jackknife, or roll. The second is the debris field. Truck tire treads can weigh 20 to 30 pounds or more and travel significant distances when they separate, becoming obstacles that other vehicles cannot avoid. Drivers on I-75 through Lexington or on I-65 between Louisville and Bowling Green encounter this debris regularly. When a debris strike causes a crash or forces a vehicle off the road, the originating truck and its carrier are generally responsible for the resulting injuries.

Who Is Legally Responsible for a Truck Tire Blowout

Responsibility depends on which failure caused the blowout. The motor carrier is responsible for maintaining proper tire pressure, inspecting tires before each trip, and replacing worn or damaged tires under 49 CFR Part 396. The driver is responsible for pre-trip inspection. If a manufacturing defect caused a tire that was otherwise properly maintained to fail, the tire manufacturer may face product liability exposure. Attorney Jon Hollan has noted that physically examining the failed tire before it is disposed of is critical in these cases, because the tire itself tells the story of whether the failure was maintenance-related, overload-related, or a manufacturing defect.

Recovering After a Tire Blowout Crash

Crashes caused by commercial truck tire failures often produce some of the most severe injuries seen in vehicle collision cases. When a tire explodes at highway speed, the resulting loss of control is sudden and unpredictable. Vehicles in surrounding lanes have almost no time to react. Injuries to occupants of cars struck by an out-of-control truck or hit by tire debris frequently include traumatic brain injuries, spinal cord damage, multiple fractures, and internal organ injuries that require extended hospitalization and rehabilitation.

The evidentiary challenge in tire blowout cases is connecting the specific failure mode to the responsible party. This requires a forensic examination of the tire itself, maintenance records showing when the tire was last inspected and replaced, weigh station records showing whether the truck was operating over its rated axle weight, and the driver’s pre-trip inspection report for the day of the crash. All of this evidence must be requested and preserved quickly. Under 49 CFR Part 396, carriers must maintain maintenance records, but the tire itself is the most critical piece of physical evidence and has no legal retention requirement once the truck returns to service. See the full investigation picture in our Truck Talk on investigations.

Injuries from tire blowout crashes frequently include not only the direct impact injuries from the collision but also injuries from the sudden, violent nature of the vehicle’s response to the tire failure. Whiplash, shoulder and neck injuries from bracing against an impact, and psychological trauma from a high-speed loss of control are all documented outcomes. The full scope of damages in these cases extends well beyond the initial emergency room visit and includes ongoing medical treatment, physical therapy, and in serious cases, permanent limitations that affect every area of daily life. Connecting those long-term consequences to the initial maintenance failure through a chain of documented evidence is the work of building a complete truck tire blowout case. Our truck accident practice page covers the full range of recoverable damages.
