Companies that sell second hand retread tires often say that their products are no more prone to blowouts than new tires, and safety studies on the subject seem to support this claim, according to one automotive expert’s independent research. While retread tires were once a common replacement option for passenger vehicle owners, an influx of inexpensive tires imported into the United States has made new tires less expensive, according to retread tire distributors, and nearly eliminated the market for retread passenger vehicle tires. One auto part retailer reported not selling a retread passenger vehicle tire for more than a decade. Retread tires are now used almost exclusively by commercial vehicles – from tractor trailers to jet planes, according to retread industry representatives. Approximately four in five aircraft tires currently in service are retreads, according to industry estimates. The safety statistics touted by the retread industry were supported by tire manufacturers and auto associations as well.
Tire retreading is a $3 billion industry according to industry representatives, and approximately 730 tire retreading facilities are currently operating in the United States.
One common reason for the mistaken idea that retreads are less durable than new tires, according to the auto expert’s research, is the seemingly disproportionate amount of tractor trailer tire debris found on U.S. roadways, which some drivers say is a road hazard and accident risk. Trucks, with many more tires than passenger vehicles, tend to travel larger distances for longer amounts of time than other vehicles and are therefore more prone to blow outs, no matter what type of tires they have.
According to a safety study commissioned by the United States National Highway Transportation Safety Administration in 2008, compared the amount of road debris left on highways by damaged retread tires to the amount left by new tires and found no appreciable difference between the two. Overall, commercial truck collisions found to be caused by damaged truck tires whether retreads or new tires amount to less than one percent of all auto accidents, according to National Highway Transportation Safety Administration statistics.
An estimated 8 of every ten tires are recycled, according to statistics reported by the tire industry, and many of these tires become retreads. While manufacturing a new truck tire requires 22 gallons of oil, while retreading a used tire requires about 7 gallons, according to retread industry representatives. The retread process also uses less rubber and energy than producing a new tire. Every year, approximately 60 million tires are improperly discarded in landfills where they pose toxic fire hazards.
