On Oct. 27, 2015, NTSB issued a press release unveiling a special investigation report which states that NTSB found that the way tires are currently registered and recalled is ineffective. It also said there is insufficient guidance by the tire and automotive industries on the risks associated with tire aging. According to the report, NTSB found that for the 3.2 million tires recalled from 2009-2013, the recall completion rate was only 44 percent. NTSB also reports that only about 20 percent of affected tires are returned to the manufacturer. This compares to a 78% recall completion rate that exists for vehicles.
As a result of the study, the NTSB makes nine recommendations to NHTSA to improve registration and recall processes, develop better guidance for consumers on issues related to tire aging and service life, and promote technological innovations that will reduce tire-related crashes. The NTSB also made recommendations to AAA, the RMA and tire manufacturers.
An executive summary of the report, including findings and safety recommendations, is available at https://go.usa.gov/c3pQH. The full report will be posted on the NTSB website in several weeks.
