WARNING:
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in air bag system section before performing service on or around the air bag system compo-
nents or wiring. Failure to follow WARNINGS could result in unintentional activation of the system
or could render the system inoperative. Either of these two conditions may result in severe injury.
The procedures in this section must be followed in the order listed to disable the air bag system tem-
porarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures could
result in possible activation of the air bag system, personal injury or otherwise unneeded air bag sys-
tem repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

WHEELS AND TIRES
NOTE:
All wheel fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of the same
part number or with an equivalent part if replacement becomes necessary. Do not use a replacement part
of lesser quality or substitute design. Torque values must be used as specified during reassembly to as-
sure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.

GENERAL DESCRIPTION
TIRES
This vehicle is equipped with following tire. P215 / 65 R16, 215 / 65 R16 or 235 / 60 R16
The tires are of tubeless type. The tires are designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressure.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively rapid
acceleration, and unnecessary sharp braking increase tire wear.
WHEELS
Standard equipment wheels are following steel wheel. 16 6 1 / 2 J or 16 7JJ
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to the Tire Placard. Re-
placement 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 clear-
ance and tire or snow chain clearance to the body and chassis.
NOTE:
Do not mix different types of tires on the same vehicle such as radial, bias and bias-belted tires except in
emergencies, because vehicle handling may be seriously affected and may result in loss of control.
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.

The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire
Placard. Metric tire gauges are available from tool suppliers. The
chart, left table, converts commonly used inflation pressures from
kPa to psi.kPakgf / cm2psi

WHEELS REPLACEMENT
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in left figure may cause ob-
jectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may affect
wheel and bearing life, brake cooling, speedometer / odometer cal-
ibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use 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 and radial runout at both
inside and outside of the rim flange. With 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 correc-
tion 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 ªaº: 1.20 mm (0.047 in.)
Radial runout limit ªbº: 1.20 mm (0.047 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).

TIRE PLACARD
The tire placard is located on the driver's side door lock pillar and
should be referred to for tire information. The placard lists the maxi-
mum load, tire size and cold tire pressure where applicable.
TIRE ROTATION
To equalize wear, rotate tires periodically as shown in figure.
