Lower than recommended pressure can cause:
• Tire squeal on turns
• Hard Steering
• Rapid and uneven wear on the edges of the tread
• Tire rim bruises and rupture
• Tire cord breakage
• High tire temperature
• Reduced handling
• High fuel consumption
Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement tires should be of the same size, load
range and construction as those originally on the vehicle.
Use of any other size or type tire may affect ride,
handling, speedometer / odometer calibration, vehicle
ground clearance and tire or snow chain clearance to the
body and chassis.
It is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to
equalize braking traction.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.
The metric term for tire infl ation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS7RS0B2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.
How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
accurate dial indicator. The tire may be on or off the
wheel. The wheel should be installed to the wheel
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial
runout “b” at both inside an d outside of the rim flange.
With the dial indicator set in place securely, turn the
wheel one full revolution slowly and record every reading
of the indicator.
When the measured runout exceeds the specification
and correction by the balancer adjustment is impossible,
replace the wheel. If the reading is affected by welding,
paint or scratch, it should be ignored.
Lateral runout limit “a”
: 0.3 mm (0.012 in.)
Radial runout limit “b”
: 0.3 mm (0.012 in.)

Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
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 DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear 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 DescriptionS7RS0B2401005
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 f aulty 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 w addle 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.

Tire Mounting and DismountingS7RS0B2406004
CAUTION!
When installing tire which has arrow
indicating tire rotation direction to wheel,
make sure that this tire rotation direction is
same as actual tire rotation direction when
vehicle is moving forward. Otherwise, it is
not possible to install wheel with tire to
vehicle in specified direction.
Use a tire changing machine to mount or dismount tires.
Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons al one 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 330 kpa (47.9 psi) pressure
when inflating. If 330 kpa (47.9 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 RepairS7RS0B2406005
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.
