2012 INFINITI G-CONVERTIBLE wheel size

8-38Maintenance and do-it-yourself
.INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) (if so equipped)
GUID-B42A4A7B-879D-4F0E-A902-69FB4ABCC6B8Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.
WARNING
. The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.
. Drive carefully while the TEMPORARY
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 pres- sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see
“Tire and Loading Informa-
tion 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 TEMPORARY
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 reduced. 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.
Emergency tire puncture repair kit
(if so equipped)
GUID-FAD28AE4-EFCF-49D5-B78F-E11D9F52D1B1The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire
punctures.
If possible, have the vehicle towed to a
facility that can repair or replace the flat
tire. Using the emergency tire puncture
repair kit may cause a malfunction of the
tire pressure sensor and cause the low tire
pressure warning light to illuminate.
