When It’s Time.for New Tires
One way to tell when it’s time for new

only%2 inch (1.6 mm) or less of tread
remaining.
You need a new tire if:

damage that can’t he repaired well

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).
