Tyre Pressure for
High-Speed Operation
Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tyres. Sustained
high-speed driving causes excessive
heat build-up and can cause sudden
tyre failure. This could cause 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 allow the vehicle to
be driven at high speeds, make sure
the tyres are rated for high-speed
operation, are in excellent
condition, and are set to the correct
cold tyre inflation pressure for the
vehicle load.
Vehicles with P245/45R17 95V, P245/
40R18 93V, or 255/35R19 96V size
tyres require inflation pressure
adjustment when driving the vehicle
at speeds of 160 km/h (100 mph) or
higher. Set the cold tyre inflation
pressure to 280 kPa (41 psi).
Vehicles with 245/40R18 93Y and 275/
35R18 95Y or 265/35ZR19 (94Y) and
295/30ZR19 (100Y) size tyres require
inflation pressure adjustment when
driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set the
cold tyre inflation pressure to 300 kPa
(44 psi).
Sustained operation at speeds over
160 km/h (100 mph) requires a load
limit of the driver and one passenger,
with no additional cargo. When loaded
above this level, up to the GVW, do
not operate the vehicle above
160 km/h (100 mph).
Return the tyres to the recommended
cold tyre inflation pressure when
high-speed driving has ended.

Pressure 0 283.
VEHICLE CARE
Tyre Pressure Monitor

System

Caution
Modifications made to the Tyre
Pressure Monitor System (TPMS) by
anyone other than an authorised
service facility may void
authorisation to use the system.
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
