Radial Tire Lead/Pull Correction Chart

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.

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

Removal

1. Loosen wheel lug nuts by half a turn, 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 the
sequence described in the figure.

Torque: 118 N·m (87lb 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.
