INDICATORS
When lt’s Time for
New Tires
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
2/32
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.
0
The tread or sidewall is cracked, cut
or snagged deep enough to show cord
or fabric.
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 Tire-Loading
Information 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 a
“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.
