286 Vehicle Care
Warning (Continued)
Consult your dealer before replacing
wheels. Never use wheels that are not
designed for the vehicle. Doing so would
impede safe vehicle operation.
You should replace your tires when:
Your tires are worn to a point where
3.2 mm (4/32 in.) (front) and 1.6 mm (2/
32 in.) (rear) or the cord or fabric is
exposed.
Your tire tread or sidewall is cracked, cut
or snagged deeply enough to expose the
core, fabric or steel components.
Your tire has a hump, bulge or split.
Your tire sustains a puncture, cut or other
damage that cannot be correctly repaired
because of the size or location of the
damage.
When replacing tires, you should use the
same size, load range and construction type
(bias or radial) as the original tires on your
vehicle. Use of any other size or type tire
may affect load carrying capacity, ride,
handling, speedometer/odometer calibration,
vehicle ground clearance and tire clearance
to the chassis. If replacing only a single tire,
it should be put on the same axle with
other tires of equal diameter.
When replacing or rotating tires, all tires on
an axle should be of the same tread design
and should have the same outside diameter
within certain limitations. Consult your
authorized dealer or tire dealer.
