Truck Tire Blowout Accidents
When 18 tires become a danger — causes, consequences, who’s responsible, and what crash victims in Kentucky need to know.
Tire blowouts cause roughly 8,000 to 11,000 commercial truck accidents every year — about 6% of all truck crashes, according to FMCSA data. When a 40-ton tractor-trailer loses a tire at highway speed, the results can be catastrophic: jackknifes, rollovers, debris strikes, and multi-vehicle pileups. The NHTSA estimates tire blowouts contribute to over 200 deaths each year. What most people don’t realize: most truck tire blowouts aren’t accidents. They’re the result of maintenance failures, improper loading, or defective equipment that someone was responsible for catching.
How Dangerous Are Truck Tire Blowouts?
A standard passenger car has 4 tires. An 18-wheeler has 18 — each one carrying a massive share of up to 80,000 pounds. More tires mean more maintenance requirements and more opportunities for failure. When one fails at 65 mph on a Kentucky interstate, the driver has fractions of a second to respond.

What Causes a Truck Tire Blowout?
Tire blowouts rarely happen randomly. Most have a traceable cause — and most of those causes involve someone’s failure to do their job:
Underinflation
Running a truck tire at incorrect air pressure is the leading cause of blowouts. An underinflated tire generates excessive heat as the sidewall flexes with each rotation. Heat buildup breaks down the rubber compounds, and the tire eventually fails — often violently. Federal regulations require drivers to check tire pressure as part of their pre-trip inspection. When a driver or company skips that check, the result can be catastrophic.
Worn or Bald Tires
FMCSA regulations require front tires to maintain at least 4/32 inch tread depth, and other tires at least 2/32 inch. Tires worn below these thresholds are defective under federal law. In 2021, FMCSA inspectors found 68,136 violations specifically for tires with insufficient tread depth. Those violations represent trucks that were operating with tires on the verge of failure.
Overloading
Federal weight limits cap tractor-trailers at 80,000 lbs gross vehicle weight. Exceeding those limits puts additional stress on every tire. Improperly loaded cargo that shifts weight unevenly also dramatically increases blowout risk on specific axles.
Defective Tires
Sometimes the tire itself is the problem. Tread separation — where the rubber separates from the underlying belt material — is one of the most dangerous tire defects. It can occur without warning at highway speed. When a defective tire causes a crash, the tire manufacturer may be liable under product liability law, in addition to any negligence by the driver or carrier.
Road Hazards and Road Debris
Potholes, debris, and other road hazards can rupture tires instantly. On Kentucky’s heavily-traveled interstates, road hazards are a constant risk. While the driver may not be at fault for striking unavoidable debris, carriers are still expected to maintain tires in a condition that minimizes catastrophic failure from normal road hazards.
FMCSA Tire Maintenance Requirements — What Carriers Are Supposed to Do
Federal regulations under 49 CFR Part 393 require carriers and drivers to:
- Inspect tires before every trip as part of the required pre-trip inspection
- Maintain tread depth at or above 4/32″ on front tires and 2/32″ on other tires
- Remove any tire with visible damage — cuts, bulges, or tread separation
- Maintain proper inflation levels
- Keep maintenance records documenting tire replacements and inspections
When a carrier fails to meet these requirements and a blowout causes a crash, those failures become direct evidence of negligence.
Types of Crashes Caused by Truck Tire Blowouts
What happens after a blowout depends on which tire fails, the truck’s speed, and the driver’s reaction. Common crash types include:
- Jackknife crashes — A drive axle blowout can cause the trailer to swing outward at an angle, sweeping across lanes and crushing other vehicles. Jackknife accidents are among the most dangerous truck crash types.
- Rollovers — A blowout on a loaded trailer can destabilize the vehicle and cause it to tip, especially on curves or ramps.
- Debris strikes — When a tire explodes, large chunks of rubber — called “road gators” — are ejected at high speed. These debris strikes can destroy windshields, cause vehicles to swerve, and trigger multi-vehicle pileups.
- Rear-end collisions — A truck that loses tire pressure and decelerates suddenly may be rear-ended, or may rear-end vehicles ahead if the driver loses control.
- Underride crashes — A blowout that causes a truck to swerve into another lane can result in an underride collision where a smaller vehicle slides beneath the trailer.
Who Is Responsible After a Truck Tire Blowout Crash?
Liability in a tire blowout case can involve multiple parties. Identifying all of them requires a thorough investigation:
The Driver
Drivers are required to perform pre-trip inspections and report tire problems. If the driver skipped the inspection, noticed a problem and kept driving, or operated the truck in a way that increased blowout risk (speeding over road debris, running overloaded), the driver can be held responsible.
The Trucking Company
The carrier is responsible for maintaining the fleet in safe condition. Maintenance records showing deferred tire replacement, ignored inspection reports, or a pattern of tire violations are all evidence of carrier negligence. Under respondeat superior, carriers are vicariously liable for their drivers’ on-the-job negligence.
The Tire Manufacturer
If the tire itself was defective — tread separation, sidewall failure, air retention problems — the manufacturer can be held liable under product liability law without needing to prove negligence, just that the tire was defective and caused the crash.
Cargo Loaders or Shippers
If improper loading created uneven weight distribution that caused excessive wear on specific tires, the party responsible for loading — whether the carrier or an independent shipper — may share liability.
Tire blowout evidence disappears fast. The failed tire, the truck’s maintenance records, inspection logs, and weight tickets are all critical.

Frequently Asked Questions
Can I sue a trucking company after a tire blowout accident?
Yes. If the trucking company failed to maintain the tires in the condition required by federal regulations — or if the driver failed to perform required pre-trip inspections — the carrier can be held liable for the crash. Maintenance records, inspection logs, and FMCSA roadside inspection history are key pieces of evidence in blowout cases.
What if the tire itself was defective?
If the tire had a manufacturing defect — such as tread separation or sidewall failure — you may have a product liability claim against the tire manufacturer in addition to claims against the driver and carrier. Product liability cases don’t require proving the manufacturer was careless; you only need to show the tire was defective and caused the crash. Preserving the failed tire is critical in these cases.
What evidence is important in a tire blowout crash case?
Key evidence includes: the failed tire itself (preserve it — don’t let the carrier dispose of it), truck maintenance records showing tire inspection and replacement history, pre-trip inspection logs, weight tickets showing load distribution, FMCSA inspection records showing prior tire violations, driver logs and ELD data, black box data showing speed and braking at the time of the blowout, and surveillance or dashcam footage of the crash.
Are truck tire blowouts covered by the driver’s insurance?
The trucking carrier’s commercial liability insurance covers crashes caused by blowouts, regardless of the specific cause. The minimum coverage is $750,000, but most serious crashes exceed this. When a tire defect is involved, the tire manufacturer’s product liability coverage may provide additional recovery. Identifying all available insurance is an essential part of any tire blowout claim.
What should I do if I was hit by truck tire debris on the highway?
Call 911. Get a police report. If possible, photograph the debris, the truck (get the DOT number and license plate), and any visible tire damage. Get medical attention even if you feel okay — injuries from debris strikes and secondary crashes can have delayed symptoms. Contact a truck accident attorney before speaking with any insurance company. The carrier’s team will be investigating immediately — you need representation in place fast.
