SECTION H - WHEELS, TYRES AND
STEERING WHEEL
CAUTION:
HSV vehicles are equipped with a Supplemental Restraint System (SRS). An SRS
consists of seat belt pre-tensioners (fitted to all front seats), and a driver’s-side air
bag or a driver’s-side air bag AND a passenger’s-side air bag. Refer to CAUTIONS,
Section 12M, before performing any service operation on or around SRS
components, the steering mechanism or wiring. Failure to follow the CAUTIONS
could result in personal injury or unnecessary SRS system repairs.
PURPOSE
The purpose of this section is to provide information on the wheels, tyres and steering wheel fitted to the HSV VT
and HSV VS models . The inf or mation is des igned to s upplement that given in the Holden VT and VS Series Service
Information CD’s and details are given where differences occur between the HSV models and standard Holden
models. A series of instruction drawings describe the design changes and indicate specific part numbers, fitting
instructions and relevant notes for vehicle servicing.
NOTE:
If specific technical data on a HSV model is not contained in this supplement, obtain data for that model from the
relevant Holden VT or VS series Service Manual Supplement. References are made throughout this section to
Holden VT and VS Series Service Information CD’s, to assist in providing information for specific service
operations.
CAUTION:
W hen hois ting (or j acking) HSV models , ensure that the lifting head of the hoist lifts on the chas sis before the arm
of the hoist contacts the side-skirt

WHEELS AND TYRES
GENERAL DESCRIPTION
HSV VT and VS m odels are fitted with alloy wheels developed spec if ic ally for each HSV applic ation. A new range of
wheels, called the “ T ” series, is fitted to the HSV VT models: VS models are fitted with the “ S ” series. Several
types and sizes of wheel are manuf actured to suit the various applic ations and each wheel is m anufactured fr om a
single-piece alloy casting.. Similarly, wheels with varying OFFSETS are employed to match the suspension
requirements of each HSV model. The new range of wheels used on HSV VT models include 5-spoke and 10-
spoke wheels which are available in 17 and 18 inch diameter.
NOTE:
Specific wheel nuts are used to attach `T’ Design wheels to the vehicle. These nuts are fitted with a plastic dress
cap which must be removed prior to undoing the wheel nuts.
CAUTION:
DO NOT USE THE VS ‘S’ SERIES WHEEL NUTS ON VT ‘T’ SERIES WHEELS AS FAILURE OF THE WHEEL
MAY RESULT

SERVICE OPERATIONS
Alloy wheels fitted to all HSV vehic les are to be serviced in ac cordance with the proc edures detailed in the relevant
Holden Series Service Information CD. In addition, particular care should be taken with the surface finish of alloy
wheels. The manufacturer recommends that alloy surfaces be treated the same as high-gloss painted surfaces to
prevent corrosion and general deterioration.
WHEEL AND TYRE BALANCING
In order to balance the HSV `S’ and `T’ Design wheels and tyre assemblies, refer to the relevant Holden Series
Service Manual Supplement.
NOTE:
HSV wheels are balanced with concealed weights. T he lateral distance between these weights is c onsiderably less
than the actual width of the wheel. To achieve wheel balance within specification with concealed balance weights,
set the balancing machine for a wheel width of 5.5". Figure H-1 also explains this requirement.
The following HSV Wheels and tyre combination are fitted to HSV VT and HSV VS vehicles:
Manta and ClubSport:
5-spoke, 17” x 8” (48P) using 235/45 ZR17 Medium Profile tyres
GTS:
5-spoke, 18” x 8” (48P) using 235/40 ZR18 Low Profile tyres
Senator Sedans And Estates:
10-spoke 17” x 8” (48P) using 225/55 R17 95W High profile tyres
Maloo:
5-spoke 17” x 7” (37P) using 225/45 ZR17 Medium Profile tyres
Grange:
10-spoke 17” x 8” (40P) S wheel using 225/55 R17 95W tyres.

CAUTION:
HSV VT and VS vehicles are equipped with AIR BAGS. An AIR BAG is a Supplemental Restraint System (SRS).
Refer to CAUT IONS, Sec tion 12M, in the Holden VS Series Service Inform ation CD or Section12M, in the Holden
VT Series Service Information CD before performing any service operation on or around SRS components, the
steering mechanism or wiring. Failure to follow the CAUTIONS could result in air bag deployment, resulting in
possible personal injury or unnecessary SRS system repairs.
The steering wheel assembly fitted to all HSV VT and VS models incorporates a HSV-design central horn pad
com plete with HSV logo(see F igure H-2). The c entral horn pad also incorporates the driver’s-side air bag. All other
com ponents, fixtur es and fast eners are identical to s tandard Holden parts and theref ore, any service operations on
the assembly should be carried out in accordance with the appropriate sections of the VS Series Service
Information CD or Section 9A - STEERING or Section 9B - SPEED SENSITIVE POWER STEERING in the VT
Series Service Information CD.
