40 Vehicle Care
Caution (Continued)
(20 °F). Always store high
performance summer tires
indoors and at temperatures
above 7 °C (20 °F) when not in
use. If the tires have been
subjected to 7 °C (20 °F) or less,
let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always
inspect tires before use. See Tire
Inspection in the owner s
manual.
Tire Pressure for
High-Speed Operation
Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause a crash, and
you or others could be killed.
Some high-speed rated tires
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 tires are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tire inflation
pressure for the vehicle load.
ZL1 and SS with the 1LE package
are equipped with 285/30ZR20
(95Y) and 305/30ZR20 (99Y) or
305/30ZR19 (98Y) and 325/30ZR19
(101Y) size tires that are capable of
high-speed use. Make sure vehicles
with this size tires are inflated to
300 kPa (44 psi) before operating
the vehicle at sustained high-speed
operation at speeds over 160 km/h
(100 mph).
LS/LT with the 1LE package is
equipped with 245/40ZR20 95Y and
275/35ZR20 98Y size tires that are
capable of high-speed use. Make
sure vehicles with this size tires are
inflated to 280 kPa (41 psi) before
operating the vehicle at sustained
high-speed operation at speeds
over 160 km/h (100 mph).
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See Vehicle Load
Limits and Tire Pressure in the
owner s manual.
