2018 INFINITI Q70-HYBRID tire size

8-36Do-it-yourself
ble tire or differential damage.
. Drive carefully while the TEMPOR-
ARY USE ONLY spare tire is installed.
Avoid sharp turns and abrupt braking
while driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2
bar). Always keep the pressure of the
full size spare tire (if so equipped) at
the recommended pressure for stan-
dard tires, as indicated on the Tire
and Loading Information label. For
Tire and Loading Information label
location, see “Tire and Loading In-
formation label” in the index of this
manual.
. With the TEMPORARY USE ONLY
spare tire installed do not drive your
vehicle at speeds faster than 50 MPH
(80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the front wheels and original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
.Do not use tire chains on a TEM-
PORARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
. Because the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is re-
duced. To avoid damage to the
vehicle, do not drive over obstacles.
Also do not drive the vehicle through
an automatic car wash since it may
get caught.
