A tire blowout on an 18-wheeler is frequently the result of under-inflation, worn tread, an overloaded trailer, or a defective retread — not random chance. Federal regulation 49 CFR § 393.75 requires commercial vehicles to maintain minimum tread depth and prohibits certain damaged or defective tires from being on the road. If a blowout caused your crash, the trucking company, a maintenance contractor, or a tire manufacturer may be liable. Call (956) 686-4357 for a free consultation.

When a commercial truck tire fails at highway speed, the results are often catastrophic — the truck can jackknife, the trailer can swing into adjacent lanes, or the driver can lose control entirely. In South Texas, extreme summer heat adds another real risk factor: heat dramatically accelerates tire degradation, and an already-worn or under-inflated tire is far more likely to fail on a hot McAllen or RGV highway in July than in a milder climate.

What Causes Commercial Tire Blowouts

  • Under-inflation — the single largest cause of commercial tire failure; a tire running low on air flexes more, builds heat, and separates
  • Worn tread or dry rot — federal rules require adequate tread depth on steering axle tires specifically
  • Overloading — a trailer loaded beyond its rated capacity puts more stress on every tire
  • Defective retreads — retread tires are common in commercial trucking and, when improperly manufactured or applied, can separate at speed

Who Can Be Liable

Because federal law (49 CFR § 393.75) requires carriers to inspect tires as part of routine vehicle maintenance, a blowout caused by a tire that should have been caught in inspection can support a negligence claim against the trucking company. If the tire itself was defectively manufactured, the tire maker may face a separate product liability claim. If a third-party maintenance shop serviced the vehicle, that shop may share liability too — which is why preserving the physical tire and the carrier’s maintenance logs immediately after a crash is critical.

What to Do After a Tire-Blowout Crash

  • Get medical attention and request a police report
  • If safe, photograph the failed tire, the debris field, and the DOT number on the trailer/tractor
  • Do not let the trucking company’s insurer take possession of or dispose of the tire before it can be independently inspected
  • Call a truck accident lawyer quickly — carriers routinely dispose of failed tires and overwrite maintenance logs on a rolling schedule
