Repair Instructions

General Balance Procedures

S6JB0B2406001

Deposits of mud, etc. must be cleaned from inside of rim.

WARNING

Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each tire should be inspected for any damage, then
balanced according to equipment manufacturer’s
recommendation.

Off-Vehicle Balancing
Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers. They are easy to use
and give a dynamic (two plane) balance. Although they
do not correct for drum or disc unbalance as does on-
vehicle spin balancing, this is overcome by their
accuracy, usually to within 1/8 ounce.

On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer’s instructions during balancing operation.

WARNING

Wheel spin should be limited to 35 mph (55
km/h) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION

For vehicle equipped with ABS, using on-
vehicle balancing method with ignition
switch ON may set malfunction diagnostic
trouble code (DTC) of ABS even when system
is in good condition.
Never turn ignition switch ON while spinning
wheel.

Tire Rotation

S6JB0B2406002

To equalize wear, rotate tires according to figure. Radial
tires should be rotated periodically. Set tire pressure.

NOTE
Due to their design, radial tires tend to wear
faster in the shoulder area, particularly in
front positions. This makes regular rotation
especially necessary.

[A]: 5-tire rotation

NOTE
Applicable to vehicles equipped with 5
tires including spare tire all of which are
identical in size

[B]: 4-tire rotation

LH: Left-hand drive

RH: Right-hand drive

Wheel Removal and Installation

S6JB0B2406003

Removal

1) Loosen wheel nuts by approximately 180

° (half a

rotation).

2) Hoist vehicle.
3) Remove wheel.

CAUTION

Never use heat to loosen tight wheel because
application of heat to wheel can shorten life
of wheel and damage wheel bearings.

Installation
For installation, reverse removal procedure, noting the
following.
• Wheel nuts must be tightened in sequence and to

proper torque to avoid bending wheel or brake drum
or brake disc as shown in the figure.

NOTE
Before installing wheels, remove any build-
up of corrosion on 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 vehicle is moving.

Tightening torque
Wheel nut (a): 100 N·m (10.0 kgf-m, 72.5 lb-ft)

Tire Mounting and Dismounting

S6JB0B2406004

Use a tire changing machine to mount or dismount tires.
Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they
may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead
area should be well lubricated with approved tire
lubricant.
After mounting, inflate to specified pressure shown on
tire placard so that beads are completely seated.

WARNING

Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s safety
hump and cause serious personal injury.
Do not exceed 380 kPa (55.0 psi) pressure
when inflating. If 380 kPa (55.0 psi) pressure
will not seat beads, deflate, re-lubricate and
reinflate.
Over inflation may cause bead to break and
cause serious personal injury.

Install valve core and inflate to proper pressure.

Tire Repair

S6JB0B2406005

There are many different materials and techniques on
the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed
instructions on how and when to repair tires. These
instructions can be obtained from each tire
manufacturer.
