Contrary to popular belief, you can't judge a tire
by its cover.
Researchers and most experts agree that along with tread depth
and proper tire maintenance,
tire age is also crucial to your safety on the
road.
This tire was bought as new -- it has never been on the road -- but
was nearly 14 years old when purchased.
Despite its deep treads, this tire's
inside layers have been slowly decomposing and drying out,
what experts say make
it like "a ticking time bomb."

Attorney Roger Braugh shows Brian Ross that aged tires
have a higher potential for dramatic tread separation,
which in many cases
has led to tragic endings for unsuspecting motorists..
Braugh says his lawsuits
on behalf of dozens of victims have uncovered a pattern of corporate
neglect
and government inaction on the issue of aging tires.

This graphic breaks down the various codes in the Department
of Transportation's serial number for tires.
A cryptic code of four numbers
at the end of the 12-digit DOT serial number can tell the
consumer which week
and year a tire was manufactured.
Can you tell when your tires were made?
This tire's DOT code indicates that it was
made in the 41st week of 1994.
Tires made in the 1990s have three numbers at
the end of the DOT code, while tires made after 2000 have four numbers.

This tire is more than seven years old. It
was made in the 13th week of 2001.
According to experts like Sean Kane, who
runs a private auto safety research firm, tires older than six years
get increasingly
more dangerous regardless of how long they've actually been on the road.

ABC News' "20/20" sent
producers undercover, rigged with hidden cameras,
to tire retailers all over the county to see if
any old tires are being sold as new.
The undercover producers found half a
dozen tires older than six years at
this Sears in Jersey City , N.J.
-
Some were even older than a decade.

Aged Tires: A Hidden Danger on the Road?
And in the New York area, our undercover "20/20" shoppers
found several Sears stores selling tires older than six years.
Sears says it is unusual
to have old tires in their inventory and told ABC News,
"Consistent maintenance,
proper inflation and regular inspection for tread wear patterns and damage
are the keys to good tire performance.
For consumers who are concerned about
the age or condition of their tires, it is recommended they let us evaluate
their tires regularly, which we'll do free of charge."

Aged Tires: A Hidden Danger on the Road?
At another Sears store, we were told that a tire made 12 years ago,
in the 46th week of 1996, was perfectly safe.
Sears said, "We follow an inventory
process of first in, first out,
and we turn our tire inventory an average of
more than three times a year.
We note that there is a difference
of opinion in the tire industry...about the service-life limits of tires.
The safety of our
customers is a top priority for Sears, and we'll continue to work with all
interested
parties to push for a consensus on tire service limits."
