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
0
You
can see the indicators at three or more places around the tire.
e
You
can see cord or fidbric showing through the tire’s rubber.
The
tread or sidewall
is
cracked, cut or snagged deep enough to show
cord
or
fabric.
0
The tire has a bump, bulge or split.
0
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
Certification/Tire 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.
