ground clearance NISSAN 370Z ROADSTER 2014 Z34 Owners Manual

8-38Maintenance and do-it-yourself
.The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, contact a
NISSAN dealer.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “Specifications”
(P.9-8) for recommended types and sizes of
tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial) , or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could
result in serious personal injury.
. If your vehicle was originally
equipped with 4 tires that were the
same size and you are only repla-
cing 2 of the 4 tires, install the new
tires on the rear axle. Placing new
tires on the front axle may cause
loss of vehicle control in some
driving conditions and cause an accident and personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake pad/
shoe wear. See “Wheels and tires”
(P.9-9) of this manual for wheel off-
set dimensions.
. When a spare tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will
remain on after 1 minute. Contact
your NISSAN dealer as soon as
possible for tire replacement and/
or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not install a deformed wheel or
tire even if it has been repaired.

8-40Maintenance and do-it-yourself
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
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 RE-
PAIR KIT (if so equipped)
The emergency tire puncture repair kit (Emer-
gency 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.
See “Flat tire” (P.6-3) for more details.
