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 thing's 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 nuhber, make sure they are the same size,
load range, speed rating &d construction type (bias,
bias-belted or radial) as your
original
tires.
