When
It’s
Time for New Tires
Tread Wear
Indicators
One way
to
tell when
it’s time for new tires
is
to
check the
treadwear indicators,
which will appear
when your tires have
only
1/16
inch
(1.6
mm) or less of tread
remaining.
You
need
a
new tire if:
You can
see
the indicators at three or more places around the tire.
You
can see cord or fabric showing through the tire’s rubber.
The
tread or sidewall
is
cracked, cut or snagged deep enough to show
cord or fabric.
The tire has a bump, bulge
or
split.
The tire has a puncture, cut, or other damage that can’t be repaired well
because of the size or location of
the
damage.
Buying New Tires
To find
out
what kind and size
of
tires you need, look at the
CertificatiodTire label.
The tires installed on
your
vehicle when
it
was new had
a
Tire Performance
Criteria Specification (TPC Spec) number on each tire’s sidewall. When
you
get new tires, get ones with that same TPC Spec number. That way, your
vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other things during
normal service
on
your vehicle.
If
your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
If
you
ever replace your tires with those
not
having a TPC Spec number,
make sure they are the same size, load range, speed rating and construction
type (bias, bias-belted or radial) as your original tires.
