Irregular and/or Premature Wear DescriptionS6RW0D2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with
“feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS6RW0D2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will appear as 12 mm (0.47 in.) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in.).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.
Radial Tire Waddle DescriptionS6RW0D2401005
Waddle is side to side movement at the front and/or rear
of the vehicle. It is caused by the steel belt not being
straight within the tire. It is most noticeable at a low
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the faulty tire by road testing the
vehicle. If it is on the rear, the rear end of the vehicle
shakes from side to side or “waddles”. To the driver in
the seat, it feels as though someone is pushing on the
side of vehicle.
If the faulty tire is on the front, waddling is more visual.
The front sheet metal appears to be moving back and
forth and the driver feels as though he is at the pivot
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem
Detector (TPD) and following the equipment
manufacture’s recommendations.
If TPD is not available, an alternative method of
substituting known-good tire / wheel assemblies can be
used as follows, although it takes a longer time.
1) Ride vehicle to determine whether the front or rear
waddles.
2) Install tires and wheels that are known to be good
(on similar vehicle) in place of those on waddling end
of vehicle. If waddling end cannot be identified,
substitute rear ones.
3) Road test again. If improvement is noted, reinstall
originals one at a time till waddle causal tire is found.
If no improvement is noted, install known-good tires
in place of all four. Then reinstall originals in the
same manner.
[A]: Hard Cornering, under inflation or lack of tire rotation
[B]: Incorrect wheel alignment, tire construction not uniform or wheel
heavy acceleration

Equipment manufacture’s recommendations
Radial Tire Lead / Pull DescriptionS6RW0D2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from
the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
• Rear tires will not cause lead.
Balancing Wheels DescriptionS6RW0D2401007
There are two types of wheel and tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.Dynamic balance, as shown in figure, is the equal
distribution of weight on each side of the wheel
centerline so that when the tire spins there is no
tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause
shimmy.
Inflate tires to recommended pressure

Wheel (with Tire) Removal and InstallationS6RW0D2406003
Removal
CAUTION!
Never use heat to loosen tight wheel because
the application of heat to wheel causes the
wheel life shorter and the wheel bearing
damage.

1) Loosen wheel nuts by approximately 180° (half a
rotation).
2) Hoist vehicle.
3) Make sure that the vehicle will not fall off by trying to
move vehicle body in both ways.
4) Remove wheel nuts except one.
5) Support the wheel and/or tire not to drop the wheel
and then remove the nut left with the wheel.
Installation
For installation, reverse removal procedure, noting the
following.
• Wheel nuts must be tightened in sequence and to
specified torque to avoid bending wheel or brake disc
or drum as shown in the figure.
NOTE
Before installing wheels, remove any build-
up of corrosion on wheel mounting surface
and brake disc or drum mounting surface by
scraping and wire brushing. Installing wheels
without good metal-to-metal contact at
mounting surfaces can cause wheel bolts to
loosen, which can later allow a wheel to
come off while vehicle is moving.

Tire Mounting and DismountingS6RW0D2406004
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 specified pressure when
inflating. If specified pressure will not seat
beads, deflate, re-lubricate and reinflate.
Over inflation may cause bead to break and
cause serious personal injury.

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 330 kPa (47.9 psi) pressure so
that beads are completely seated. Then adjust pressure
to specified shown in the tire placard.
Tire RepairS6RW0D2406005
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.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS6RW0D4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at various speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes.
Brake Fluid Leaks
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components
(piston cups and brake hoses) in the hydraulic system to
deteriorate.
If the above fluid is included in the system, replace the
master cylinder assembly and other rubber components
(hoses). The master cylinder assembly is disassemble
parts to maintain the performance.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
