Firestone North America Tire, LLC (BFNT) has a practical suggestion
for commemorating the presidency of Abraham Lincoln. While Lincoln
is broadly associated with a multitude of accomplishments and
characteristics, from his humble upbringing to the Gettysburg
Address, perhaps a lesser-known claim to fame is Honest Abe's
contribution to 21st century automotive maintenance.
That's
right, Abe Lincoln has made a significant contribution to car
care. The Lincoln penny test has become a tried-and-true method
of determining when it's time to get new tires. The procedure
is as simple as placing a penny in the tread and using Abe Lincoln's
likeness as your guide.
Here's
the three-step "penny test:"
1.
Take a penny and pinch Abe's body between your thumb and forefinger.
2.
Put Lincoln's head into one of the grooves on the tread. Select
a point on your tire where tread appears the lowest.
3. If any part of
Abe Lincoln's head is obscured by the tread, you're driving
with the legal and safe amount of tread. If you can see above
his head, where it says "In God We Trust," take a
hint: you're ready for a new tire.
Why
worry about tread depth? If your tread gets below 2/32 of an inch,
your car's ability to grip the road in adverse conditions is greatly
reduced. Furthermore, insufficient tread is not only dangerous;
in many states it is illegal (legal tread depth is 2/32 of an
inch - the exact distance from the tip of Abe's head to the rim
of a penny).
In
addition to tread depth, three other factors will affect your
tire's safety and performance, and can best be remembered with
three key words — inflate, rotate and evaluate. Inflation pressure
should be checked monthly and should always be kept at the automobile
manufacturer's recommended pressure. For maximum mileage, tires
should be rotated every 5,000 miles. Also, frequent visual checks
can alert car owners to obvious signs of wear or damage.
