Tyre Pressure for
High-Speed Operation
WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tyres.
Sustained high-speed driving
causes excessive heat build-up
and can cause sudden tyre
failure. You could have a crash
and you or others could be killed.
Some high-speed rated tyres
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions are such that a
vehicle can be driven at high
speeds, make sure the tyres are
rated for high-speed operation, in
excellent condition, and set to the
correct cold tyre inflation pressure
for the vehicle load.
If your vehicle has 235/50ZR18,
255/40ZR19 or 285/35ZR19 size
tyres, they will require inflation
pressure adjustment when driving
your vehicle at speeds of 160 km/h
(100 mph) or higher. Set the cold
inflation pressure to the maximum
inflation pressure shown on the tyre
sidewall or 300 kPa (44 psi),
whichever is lower. See the
example following. When you end
this high-speed driving, return the
tyres to the cold tyre inflation
pressure shown on the Tyre and
Loading Information label. See
Vehicle Load Limits on page 9 9
and Tyre Pressure on page 10 61.

Tyre Pressure Monitor

System

Notice: Modifications made to the
Tyre Pressure Monitor System
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
system.
Vehicle Care
The Tyre Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tyre pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle's
tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Each tyre, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tyre inflation
pressure label. (If your vehicle has
tyres of a different size than the size
indicated on the vehicle placard or
tyre inflation pressure label, you
should determine the proper tyre
inflation pressure for those tyres.)
As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is significantly
under-inflated.
