Truck tire failures are still a big safety headache on United States highways, and they keep leading to thousands of crashes, expensive cargo delays, and injuries that could’ve been avoided each year.  

Federal crash info points to large trucks being involved in about 170,000 injury crashes and over 5,000 fatal crashes every year, while safety groups in trucking say that underinflated tires may be behind something like 75% of tire-related incidents.  

Tire defects, plus general breakdowns, are among the main causes behind commercial truck accidents right here in the United States. Since commercial trucks haul heavy loads and cover long distances, their tires take a ton of punishment from weight, heat, rough road conditions, and just plain constant use.  

When a passenger car tire goes, the damage is serious, no doubt. Still, when an 80,000-pound commercial truck loses a tire while rolling down the highway at speed, the result is often totally catastrophic, like there’s no real recovery.  

In this guide, we’ll dig into the most common causes of semi-truck tire blowouts and the steps that can reduce the chance of it happening.

The Six Most Common Causes of Truck Tire Failure

Improper Inflation

Correct tire pressure is the first among many important safety considerations when it comes to truck tires. When tires are under-inflated, they tend to flex, thereby producing excessive amounts of heat, which may weaken the overall structure of the tire, resulting in tread separation and/or blowouts. 

If the tires are overinflated, their performance is also greatly affected by the improper distribution of weight on the tires with the center bearing more of the load compared to other sections.

Overloading

Each commercial truck tire comes with a load rating, indicating that its design is intended to carry a specific load when inflated to a particular pressure. 

New Orleans truck accident lawyer Robert J. David believes that weight limits are required for different types of commercial vehicles. Operating the tire beyond the rated load results in excessive compression beyond its original specifications, leading to fast generation of heat and structural stress. 

According to the Federal Motor Carrier Safety Administration, a commercial motor vehicle must not be operated with overloaded tires.

Tread Wear Below Minimum Depth

The federal laws provide for a minimum tread depth on commercial truck tires. As far as the steer tires, or the front tires that control the steering, are concerned, the minimum tread depth permitted by the law is 4/32 of an inch. 

The minimum tread depth permissible for all the rest of the tires is 2/32 of an inch. Steer tires receive more strict regulation as they are actually the steering wheels. 

When the tread depth gets below this minimum, a federal offense takes place, not to mention the issue of increased safety risks, particularly when roads are wet due to insufficient drainage.

Deferred Maintenance and Inspection Failures

According to FMCSA regulations, there should be pre-trip and post-trip inspections for all drivers per 49 CFR part 396. In addition to this, any commercial vehicle should undergo an annual checkup conducted by an experienced mechanic. 

This process needs to be recorded. Carriers are supposed to keep DVIR for three months and retain annual reports for fourteen months.

By avoiding the necessary inspections or postponing repairs due to tire issues, carriers take a huge risk. Such liability becomes particularly serious when the records indicate that it was possible to identify the problem beforehand. Any failure of tires in this case results in high liability costs.

 There are a total of 2,899 cases of out-of-service tire violations from the 2025 CVSA International Roadcheck. According to FMCSA inspection compliance data, it accounted for 21.4% of all vehicle citations.  

Tire violations remain among the top causes of taking commercial vehicles out of service.

Manufacturing Defects

Not every tire failure begins with the carrier. Sometimes the whole problem shows up earlier, like when tread separation starts or when there is belt edge separation and even sidewall failures that happen because of defects from manufacturing. 

Those issues can be present while the tire is still leaving the factory, even if everything after that is handled properly. If a design flaw or a production defect is the reason for a tire failure, the manufacturer may still face liability under product liability law, regardless of what the carrier does with maintenance. 

In most of these situations, you really need a forensic tire examination by an expert so they can tell manufacturing defects apart from wear or from failures linked to upkeep or handling.

Road Hazards and Environmental Factors

Potholes, rough objects, construction sites on roads, and extreme temperatures are some of the elements that may cause tire damage that could lead to eventual tire failure. 

Temperature is especially important when dealing with commercial trucks since long-distance driving on the highways at very high temperatures results in high tire temperatures, which could be too much for tires with low pressure or those that have been used for some time.

Who Bears Liability When a Truck Tire Failure Causes an Accident

Liability for a truck tire failure accident depends on the cause of the failure and the parties responsible for preventing it. Multiple parties can bear concurrent liability:

•       The trucking company bears responsibility for maintenance, inspection compliance, and the decision to operate a vehicle with tires that fail to meet federal standards
•       The driver bears responsibility for pre- and post-trip inspections and for refusing to operate a vehicle with unsafe tires under FMCSA regulations
•       A third-party maintenance provider who performed a repair or inspection negligently may share liability under 49 CFR § 396.3, which requires carriers to ensure all parts and accessories are in safe and proper operating condition
•       The tire manufacturer may bear product liability if a manufacturing or design defect caused the failure

In accidents involving commercial truck tire failures, the carrier’s maintenance records, inspection logs, and repair documentation are usually one of the first things people go after in litigation. 

They help show whether the required inspections were done, whether tire defects were actually noticed, and whether any corrective action took place before the failure happened.

There are federal regulations that require certain records to be kept, and they exist exactly because these materials tend to be the primary proof used when liability is disputed after tire-related accidents, not just a background detail.

Federal Standards Exist for a Reason

There is no doubt that the rules on tires imposed by the federal government are not optional. 

They were adopted based on established engineering standards, and these engineering standards were adopted for the very reason that tire failures of a truck in highway traffic usually are not inconsequential incidents. 

It is essential to emphasize that the requirements for tire maintenance prescribed in the FMCSA under 49 CFR Part 393 are just the absolute minimum. 

When a tire fails and leads to a truck accident, there are two critical questions: What failed? Could it be prevented?
