When It’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 inch (1.6 mm) or less of tread
remaining.
You need a new tire if:
* You can see the indicators at three
You can see cord or fabric showing
The tread or sidewall is cracked, cut
places around the tire.
through the
tire’s rubber.
or snagggd 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 he 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
Per€omance
Criteria Specification
(TPC Spec) number on each tire’s
sidewall. When
you get new tires, get
ones with that sme 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 Spec number will be
followed by an “MS” (for mud and
snow).
. ... r .: ;.- - .
If yuu ever replace your tires with those
,not having a TPC Spec number, make
SLUT they are the same size, load range,
speed rating and construction
type
(bias, bias-belted or radial) as your
original tires.
