Tire blowouts cause violent loss of control at highway speeds. When tread separation or sudden deflation leads to a crash, injured parties often look to the tire manufacturer for compensation. Product liability against tire makers requires proving the tire contained a defect, not merely that it failed.
The Human Cost of Tire Failures
NHTSA data from 2023 documents 646 deaths in tire-related crashes. These fatalities occur disproportionately in warm weather months when pavement temperatures stress tire compounds, and on long highway trips where sustained high speeds generate heat.
The catastrophic nature of high-speed blowouts distinguishes tire cases from other vehicle defect claims. A driver suddenly fighting for control at 70 mph has little margin for error. Rollovers, lane departures, and multi-vehicle collisions commonly follow.
The Six-Year Rule
Tires age even when sitting unused. Rubber compounds oxidize and become brittle over time. Industry consensus holds that tires should be replaced after six years regardless of tread depth or apparent condition.
Manufacturers embed date codes in tire sidewalls. The DOT code’s last four digits indicate the week and year of manufacture. A code reading “2318” means the 23rd week of 2018. Consumers rarely check these codes, often running tires far past their safe service life.
Aged tires fail differently than worn tires. Tread separation, where the tread layer peels away from the tire body at speed, characterizes age-related failures. These separations often occur without warning on tires that appeared fine visually.
Types of Tire Defects
Manufacturing Defects
These defects occur during production. Air trapped between rubber layers during assembly creates weak spots. Contamination in rubber compounds prevents proper curing. Improper vulcanization leaves tires structurally unsound.
Manufacturing defects typically affect individual tires or production batches rather than entire product lines. Evidence involves examining the failed tire for anomalies inconsistent with normal wear and aging.
Design Defects
Design defects affect all tires of a particular model. The tire’s specifications, materials, or construction method create inherent danger. These cases argue that no amount of careful manufacturing could produce a safe tire from the defective design.
Design defect claims often involve belt edge separation, where the steel belts inside the tire pull away from the rubber at the belt edges. Some tire designs prove more susceptible to this failure mode than others.
Warning Defects
Even properly designed and manufactured tires require adequate warnings about their limitations. Failure to warn about age-related degradation, speed ratings, inflation requirements, and load limits can constitute actionable defects.
Warning adequacy has evolved over decades. Earlier tires carried minimal labeling. Modern tires include extensive sidewall information, but whether consumers notice or understand this information remains contested.
Proving the Defect Caused the Crash
Tire manufacturers defend vigorously by blaming driver conduct rather than product defects. Common defense arguments include:
Underinflation by the consumer caused the failure. Running tires below recommended pressure generates excessive heat and accelerates wear. TPMS (tire pressure monitoring systems) became mandatory on new vehicles in 2007, but many older vehicles lack this protection.
Impact damage from potholes, curbs, or road debris weakened the tire before failure. Manufacturers argue the driver struck something that damaged the tire, making the subsequent failure the driver’s fault.
Overloading the vehicle beyond the tire’s rated capacity caused failure. Tires have specific load ratings that consumers sometimes exceed, particularly with heavily loaded trucks or trailers.
Age and wear consistent with normal service life. Manufacturers argue the tire provided adequate service and failed only after exceeding its expected useful life.
The Critical Role of Tire Preservation
The failed tire constitutes the primary evidence in any product liability claim. Preserving the tire in its post-failure condition enables expert examination of failure patterns, construction quality, and potential defects.
Tires discarded after crashes cannot be examined. Without the physical evidence, product liability claims become nearly impossible to prove. Attorneys advise clients to preserve failed tires even before consulting counsel.
Chain of custody matters. A tire that has been stored improperly, handled by unqualified persons, or partially dismantled loses evidentiary value. Professional handling and secure storage protect the evidence.
Expert Analysis Methodology
Tire failure experts employ specialized techniques:
X-ray examination reveals internal construction, belt placement, and air pockets invisible to visual inspection. Comparison with exemplar tires of the same model shows whether the failed tire met specifications.
Microscopic examination of separation surfaces distinguishes manufacturing defects from age-related failures from impact damage. The chemistry of rubber degradation leaves characteristic signatures.
Review of manufacturing records and quality control data reveals whether the tire came from a production run with known problems. Discovery in litigation can uncover internal documents showing manufacturer awareness of defect patterns.
Recall History Matters
NHTSA maintains records of tire recalls. A tire that was subject to recall for the same type of failure that caused the plaintiff’s crash provides powerful evidence of a known defect.
Whether the consumer received recall notice and had opportunity to obtain a replacement affects comparative fault analysis. Consumers who ignored recall notices may see their recoveries reduced.
Post-accident recalls for the same tire model support claims that the manufacturer knew or should have known of defect risks.
The Firestone Precedent
The Firestone tire recall of 2000, involving over 6.5 million tires, established public awareness of tire defect risks. Hundreds of deaths linked to tread separation on Ford Explorers produced massive litigation and regulatory changes.
This episode demonstrated that tires, despite appearing simple, involve complex engineering and manufacturing processes with significant room for error. Major manufacturers have faced repeated recalls since.
Practical Considerations
Tire product liability cases require substantial resources. Expert witnesses, laboratory testing, and extensive discovery drive costs. Contingency fee arrangements make these cases accessible to injured plaintiffs, but attorneys select cases carefully based on available evidence.
Statute of limitations issues arise because tire failures can occur years after purchase. Tolling arguments and discovery rules vary by state. Prompt consultation with counsel after a tire-related crash protects legal options.
The tire on your vehicle may have been manufactured half a decade ago in a factory you never heard of. Its failure at highway speed takes seconds. The resulting litigation can take years.
