A consumer safety group is asking the federal government to require "born-on" dates for car and truck tires.
Safety Research and Strategies Incorporated is a Massachusetts based auto-safety research firm. It sent a petition last week to the National Highway Traffic Safety Administration asking for the requirement, citing crashes linked to older tires with little wear and tear.
SRS provided analysis from 50 crashes resulting in 37 deaths that involved different makes of tires. It says tire performance can begin to degrade after six years because of the rubber's age.
The tire industry is studying tire aging. But the Rubber Manufacturers Association, a Washington lobbying group, says there is no data to suggest any specific age makes a tire less strong.
