Wheels and Tires - Wheels and Tires - Overview
Description and Operation

OVERVIEW Published: 25-May-2012

A number of alloy wheel designs are available ranging from 17 to 20 inch in diameter. A Tire Pressure Monitoring System
(TPMS) is used to monitor the air pressure in each tire and inform the driver if the pressure falls below predetermined
thresholds.

All wheels are of cast construction in aluminum alloy with the choice of wheel design dependant on the vehicle trim level and
engine derivative.

On normally aspirated petrol models and all diesel models a 4J X 18 inch temporary spare wheel is supplied as standard,
supercharged petrol models are supplied with a 4Jx19 inch temporary spare wheel. In some major European markets an Instant
Mobility System is offered as an alternative to the spare wheel. The Instant Mobility System is capable of providing a
temporary repair and tire inflation to a puncture of up to 6mm in diameter in the tread area of the tire. A puncture in the tire
wall cannot be repaired using the system.
The vehicle jack and accessories are stored in the spare wheel-well in the luggage compartment.

Tire Changing

WARNINGS:


Tires must be inflated to the recommended pressures when the tires are cold (ambient temperature) only. Refer to label
on the 'B' pillar for recommended tire pressures. If the tires have been subjected to use or exposed to direct sunlight, move
the vehicle into a shaded position and allow the tires to cool before checking or adjusting the pressures.


Valve stem seal, washer nut, valve core and cap should be replaced at every tire change. Valve stem seal, washer and
nut must be replaced if the valve retention nut is loosened. Sensor units and nuts must be fitted using correct torque figures
and associated profile. Damage to the vehicle and consequently injury to the vehicle's occupants may result if these
instructions are not adhered to.


NOTE: The TPMS valve should be serviced using the suitable service kit, each time the tyre is dismounted, to ensure an
air tight seal. Attention should be made to the detail of fitting this kit.

Vehicles fitted with TPMS can be visually identified by an external metal locknut and valve of the tire pressure sensor on the
road wheels. Vehicles without TPMS will have rubber tire valve.

1 Tire valve and pressure sensor 2 Tire fitting/removal tool initial start position 3 High tire and bead tension area 4 Low tire and bead tension area When removing the tire, the bead breaker must not be used within 90 degrees of the tire valve in each direction on each side
of the tire.

When using the tire removal machine, the fitting arm start position must be positioned as shown in the tire changing
illustration for each side of the tire. The wheel can then be rotated through 180 degrees in a counter-clockwise direction. This
will relieve tension from the tire bead allowing the remaining 180 degrees of the tire to be manually pulled from the rim.

When refitting the tire, position the fitting arm as shown. Rotate the tire and take care that the bead on the low tension side
of the tire does not damage the sensor.

Run-Flat Tires

Run-flat tires are not available on vehicles from 2011MY.

TREAD Act - NAS Only

Vehicles supplied to the North American markets must comply with the legislation of the Transport Recall Enhancement,
Accountability and Documentation (TREAD) act. Part of the requirement of the TREAD act is for the vehicle to display a label
which defines the recommended tire inflation pressure, load limits and maximum load of passengers and luggage weight the
vehicle can safely carry. This label will be specific to each individual vehicle and will be installed on the production line. The
label is positioned on the driver's side 'B' pillar on NAS vehicles and the inside rear face of the LH door on Canadian
specification vehicles.

This label must not be removed from the vehicle. The label information will only define the specification of the vehicle as it
came off the production line. It will not include dealer or owner fitted accessory wheels and tires of differing size from the
original fitment.

If the label is damaged or removed for body repair, it must be replaced with a new label specific to that vehicle. A new label is
requested from Jaguar parts and will be printed specifically for the supplied VIN of the vehicle.

Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitoring System (TPMS) is a driver assistance system which assists the driver to maintain the tire
pressures at the optimum level. TPMS is standard fitment on NAS vehicles and an optional fitment in other markets. TPMS

Component Tests

Wheels and Tires

For wheel and tire specification information (pressures, torques, etc).

When replacing wheels or tires, local legislation regarding health and safety must be complied with.

If the vehicle has a Tire Pressure Monitoring System installed, only Jaguar approved wheels and tires should be used. If the
wheel and tire size is changed (for example from R18 to R20) the Tire Pressure Monitoring System module should be updated
with the correct pressure information appropriate to the new wheel and tire set. Update the Tire Pressure Monitoring System
module using the Jaguar approved diagnostic system.
As a general guideline, only replace tires in pairs or as a set, and only with tires of equivalent size and specification.
Confirm the symptoms of the customer complaint.
As much information as possible should be gathered from the driver to assist in diagnosing the cause(s).

1. Before a road test, carry out a basic inspection to make sure the vehicle is safe and legal to drive.

occupant position and the crash severity. To reduce the risk of an airbag module induced injury to a driver that is positioned
close to the steering wheel, the airbag module deploys radially. It has a non-azide propellant that reduces particulates and
effluents. It consists of a two stage inflator with separate chambers for the two inflation stages, each being independently
activated by the RCM. It has two electrical connectors that are color coded and mechanically keyed to the respective connector on the inflator.

Passenger Airbag Module



The passenger airbag module is controlled by the RCM which chooses between single or dual stage deployment, depending on the occupant status and the crash severity. It consists of a two stage inflator with two airbag electrical connectors to
accommodate the two stage inflation.

The heated gas inflator consists of a high-pressure mix of clean air and hydrogen gas, triggered by two separate ignition
squibs. It produces a controlled generation of clean gas to rapidly fill the airbag. It is classified as a stored flammable gas
(not as an explosive) and as such, has less restrictive storage and transportation requirements. It produces a very clean burn
and almost no particulates and is almost free of any toxins, making disposal or recycling much easier. Drivers Airbag Module
