FIG. 5-8: TIRE PLACARD INSIDE GLOVE
COMPARTMENT DOOR—TYPICAL
suit in improved fuel economy. For those
owners who prefer the utmost in comfort,
the reduced tire pressures listed on the
placard may be used when loads of (5 oc¬
cupants or less) are carried.
Vehicle Loading — Do not load your
vehicle beyond the vehicle capacity (total
pounds) shown on the tire placard. This fig¬
ure represents the design capacity of the
vehicle, not merely of the tires. When tow¬
ing trailers, the allowable passenger and
cargo load must be reduced by an amount
equal to the trailer tongue load on the
trailer hitch. (See "Trailer Towing" in Sec¬
tion 1 of this manual.) Vehicles equipped
with luggage racks do not have a vehicle
load capacity greater than specified on the
tire placard.
Tire Wear and Rotation — Uneven or
abnormal tire wear is usually the result of
incorrect inflation pressure, lack of regular
rotation, improper wheel alignment, wheels
being out-of-balance, or poor driving habits.
Underinflation, incorrect toe or camber and
fast cornering produce different types'of ab¬
normal wear which can be diagnosed by
your dealer.
The original equipment tires incorporate
built-in tread wear indicators, Fig. 5-9, to
assist you in determining when your tires
have been worn to the point of needing re¬
placement. These indicators appear as 1/2
inch wide bands when tire tread depth is
1/16 inch or less. When the indicators ap¬
pear in two or more adjacent grooves at 3
locations around the tire, or when cord or
