Typical examples of abnormal tire ahead wear and major
causes:

CAUTION: Similar wear patterns can be caused by
worn suspension parts, misalignment of wheels and
tires, and other suspension related problems.

Spotty wear – wear localized on shoulder sections, and in
an extreme cases, the tire becomes polygonal in shape.

480RW002

1. Tire or wheel out of round or distorted.
2. Hub or knuckle out of round or distorted.
3. Play in hub bearings or ball joint.
4. Rotating parts out of balance.

Tread wear one-sided.

480RW003

1. Rotating parts out of balance.
2. Tire or wheel out of round.
3. Hub or knuckle out of round or distorted.

3E–7

Localized tread wear.

480RW004

1. Once spotty wear develops in tread due to hard

braking or abrupt starting, localized wear tends to be
promoted.

Shoulder wear (generally wear develops in outer
shoulder):

480RW005

1. Camber or toe-in incorrect.
2. Shoulder wear caused by repeated hard-cornering.

Wear in shoulders at points opposed to each other.

480RW006

1. Tire or wheel out of round or distorted.
2. Play in bearings or ball joint.

Premature wear in shoulders.

480RW007

1. Flexing of tire excessive due to under-inflation.

Legend

(1) Wheel Lug Nut
(2) Wheel and Tire

Removal

1. Loosen wheel lug nut by approximately 180 g (half a

rotation), then raise the vehicle and remove the nuts.

2. Remove wheel and tire.

NOTE: Never use heat to loosen a tight wheel lug nut.
The application of heat to the hub can shorten the life of
the wheel and may cause damage to wheel bearings.

Installation

1. Install wheel and tire.
2. Install wheel lug nut, and lower the vehicle. Tighten

the wheel lug nuts to the specified torque in numerical
order.

Torque: 118 N·m (87 lb ft)

CAUTION: Before installing wheels, remove any
build-up of corrosion on the wheel mounting surface
and brake disc mounting surface by scraping and
wire brushing.  Installing wheels without good
metal-to-metal contact at mounting surfaces can
cause wheel nuts to loosen, which can later allow a
wheel to come off while the vehicle is moving.

NOTE: Valve caps should be on the valve stems to keep
dust and water out.
