winter tyres JAGUAR XJ 2004 X350 / 3.G Owners Manual

7-18 Maintenance
Tyres
Tyres of the correct type, manufacturer
and dimensions, with correct cold
inflation pressures are an integral part of
every vehicle’s design. Regular
maintenance of tyres contributes not only
to safety, but to the de signed function of
the vehicle. Road-holding, steering and
braking are especially vulnerable to
incorrectly pressurised, badly fitted or
worn tyres.
Tyres of the correct size and type, but of
different make have widely varying
characteristics. It is therefore
recommended that Jaguar approved tyres
are fitted to all wheels.
A tyre recommendation placard is placed
on the inside of the fuel filler flap, giving
information specific to the vehicle’s
wheel and tyre equipment.
Always ensure that the wheel nuts are
fully seated before finally tightening the
nuts in alternate sequence.
W, Y and Z-rated performance tyres are
optimised for driving dynamics and have
limited winter traction ability. Compared
with H-rated all-season tyres, they may
incur increased tread wear, reduced ride
comfort, and increased road noise.
Tyre Renewal
When renewing tyres, it is preferable to
fit a complete vehicle set. If either front
or rear tyres only need to be renewed,
new tyres must be fitted, as axle sets,
to replace worn ones. After new tyres
have been fitted the wheels need to be
dynamically balanced. The radial ply
tyres specified are designed to meet the
high-speed performance capability of this
vehicle (see page 8 - 7) . Do not fit tyres
with a different tread pattern, size or
speed rating.
Tyre Pressures
The recommended tyre pressures are
written on a label, inside the fuel filler
flap. These tyre pressures provide
optimum ride and handling
characteristics for all normal operating
conditions. The pressures should be
checked, and correctly set each week
with the tyres cold. Tyre temperatures
and pressures increase when running.
Deflating a warm tyre to the
recommended pressure will result in
under inflation whic h may be dangerous.
A slight natural pressure loss occurs with
time. If this exceeds 2 lbf/in² (0.14 bar,
14 kPa, 0.14 kg/cm²) per week, the cause
should be investigated and rectified.
Note: It is an offence in certain countries
to drive a vehicle with tyres that are not
inflated in accordance with the vehicle’s
proper use.

Winter (Snow) Tyres
The tyres fitted as original equipment are
designed with a rubber compound, tread
pattern and width specially suited for
high speeds in normal road conditions,
but they are less suitable during extremes
of low temperatures, snow and ice.
The use of winter tyres will considerably
improve the vehicle’s handling during
these conditions.
It is recommended that only Jaguar
approved winter tyres are used (refer to
Wheels and Tyres on page 8 - 7).
!WARNING:
Do not exceed the tyre speed rating
when using winter tyres.
Tyre directional indicators must be
rotating in a clockwise direction when
viewed from the right-hand side of the
vehicle, and anti-clockwise when viewed
from the left-hand side of the vehicle.
Winter tyres must be used in vehicle sets,
that is, fitted on all four wheels.
Snow Chains
Snow chains, of the recommended type,
may only be fitted to rear wheels.
Contact your Jaguar Retailer for details
and availability of approved snow chains.
The maximum speed when using snow
chains is 30 mph (48 km/h).
Remove the snow chains immediately the
roads are clear of snow.
Ensure the fitting instructions supplied
with the snow chains are kept in a safe
place, for example, wi th this literature
pack.
Note: Dynamic Stability Control MUST
be switched OFF when using snow chains.
