1 General Information

With the following exceptions, MY 2003 VY Series Cab Chassis Wheel and Tyre information carries over from MY 2003

VY Series vehicles. For information not covered within this Section, refer to Section 10, Wheels And Tyres in the MY

2003 VY and V2 Series Service Information.

• The spare wheel hoist mounting and access is unique.

• The stowage of the jack, jack/wheel nut wrench and hoist crank handle is unique.

• The steel wheel as fitted to cab chassis base models is unique to accommodate the increased load carrying

requirements.

• The alloy wheel as fitted to cab chassis ‘S’ Pack is unique to accommodate the increased load carrying

requirements.

• The tyres as fitted to all cab chassis models are unique to accommodate the increased load carrying requirements.

1.2 Tyre Placards

Wheel and tyre sizes, inflation pressures and load capacity

are specified on a tyre placard (1) located on the end

surface of the driver door (2).

Always check tyre pressures, with COLD tyres (after

vehicle has stood for three hours or more, or driven less

than 2 km) and should be checked weekly or before any

extended trip.

When checking ty re pressur e, v isual ly inspect tyres for

excessive wear, sharp objects embedded in the tyre or

damage to the sidewalls.

NOTE

Clean valve exterior, prior to applying air pressure nozzle

when inflating tyre.

NOTE

Always install valve caps to keep out dust and water.

Figure 10-4

The tyre placard shown in Figure 10-5 is typical of those

fitted to MY 2003 VY Series Cab Chassis Models.

Refer to 3. Specifications in this Section or the vehicle

tyre placard for the correct wheel/tyre size and

corresponding tyre inflation pressures.

1.3 Tyre Markings

The tyre sidewall has a coded mark ing system, w hich

provides information about the tyre.

Tyre Marking Example:

215 65 R 15 C 104 R

215 = Section Width (1) – mm (215 mm)

65 = Aspect Ratio % i.e.Section Height (2) to

Section Width (1)

(55 = 55%)

(60 = 60%)

(65 = 65%)

R = Tyre Construction

(R = Radial)

15 = Rim Diameter – inches

(15 = 15”)

(16 = 16”)

(17 = 17”)

C = Service Application Code

(C or LT = Light Truck or Multi-purpose

Passenger Vehicle)

NOTE

Some European and Japanese light truck tyres

use C instead of LT for the same purpose.

104 = Load Index – kg @ 250 kPa (36 psi) cold

inflation pressure

(97 = 730 kg max. load)

(104 = 900 kg max. load)

(106 = 950 kg max. load)

R = Speed Rating

(R = 170 km/h)

(H = 210 km/h)

2 Service Operations

2.1 Spare Wheel Hoist

Remove

1 Insert the spare wheel hoist crank handle (1) into the

aperture located at the rear of the vehicle.

2 Rotate the handle in a counter-clockwise direction

until the spare wheel (2) is completely lowered and

some slack exists in the spare wheel hoist

cable (3).

3 Support the spare wheel with one hand, and tilt the

wheel retainer (4) upward, then feed the retainer

through the wheel centre.

4 Remove the spare wheel from below the vehicle.

5 Remove the four screws (5) and lower the hoist

assembly (6) from the vehicle.

Figure 10-9

Reinstall

Installation of the spare wheel hoist is the reverse of the removal procedure, noting the following:.

• Ensure that the hoist is installed with the square coupling towards the rear of the vehicle.

• Tighten the hoist-attaching screws to the correct torque specification.
