GENERAL INFORMATION
WARNING: This is a multi-purpose vehicle
with wheels and tyres designed for both
on and off road usage. Only use wheels
and tyres specified for use on the vehicle.
The vehicle is equipped with tubeless ’S’,’T’ or ’H’
rated radial ply tyres as standard equipment. The
tyres are of European metric size and must not be
confused with the "P" size metric tyres available in
North America.
Vehicle wheel sets, including spare wheel, must be
fitted with the same make and type of tyre to the
correct specification and tread pattern. Under no
circumstances must cross-ply or bias-belted tyres be
used.
For tyre specification and pressures
See
INTRODUCTION, Information, Wheels and Tyres .
Steel wheels
Tubeless tyres are mounted on 7.0 inch wide by 16
inch diameter steel wheels.
Alloy Wheels
Tubeless tyres are mounted on 7.0 inch wide by 16
inch diameter cast aluminium alloy wheels. The
surface has a paint finish covered with a clear
polyurethane lacquer. Care must be taken when
handling the wheel to avoid scratching or chipping the
finish.
The alloy wheel rim is of the asymmetric hump
type incorporating a safety hump to improve
location of the tyre bead in its seat. If difficulty is
experienced in fitting tyres to this type of rim
See
Tyre Fitting .
WARNING: DO NOT fit an inner tube to an
alloy wheel.
TYRE INSPECTION
Inspect tyres at weekly intervals to obtain maximum
tyre life and performance and to ensure compliance
with legal requirements. Check for signs of incorrect
inflation and uneven wear, which may indicate a need
for balancing or front wheel alignment,
See Fault
diagnosis, Tyre Wear Chart , if the tyres have
abnormal or uneven wear patterns.
Check tyres at least weekly for cuts, abrasions, bulges
and for objects embedded in the tread. More frequent
inspections are recommended when the vehicle is
regularly used in off road conditions.
To assist tyre inspection, tread wear indicators are
moulded into the bottom of the tread grooves, as
shown in the illustration above.
When the tread has worn to a depth of 1.6 mm the
indicators appear at the surface as bars which
connect the tread pattern across the width of the tread
as shown in the illustration above.
