2018 INFINITI Q70 spare tire

43
Contact the manufacturer of your tires for
their position and assistance on the repair of
speed-rated tires. When you are replacing tires
that have a speed rating, you must replace
with tires of the same or higher speed rating
if the speed capability of the vehicle is to be
maintained.
VISUAL INSPECTION
INSPECT YOUR TIRES. DO NOT DRIVE ON A
DAMAGED TIRE OR WHEEL. Check your tires
frequently for scrapes, bulges, separations,
cuts, snags, cracks, penetrations or excessive
localized wear from hard braking. Also check
for abnormal tire wear, particularly on the
edges of the tire tread which may be caused
by misalignment or underinflation. Impacts
can damage the inner portion of the tire
without being visible on the outside. If damage
can be seen on the tires or wheels, or if you
suspect that possible impact damage may
have occurred, replace with spare at once and
have your tire store or retailer inspect your
tires immediately. Use of a damaged tire could
result in tire destruction. When inspecting
your tires, including the spare, check your air
pressures. If your pressure check indicates
that one of your tires has lost pressure of two
pounds or more, look for signs of penetrations,
valve leakage, or wheel damage that may
account for the air loss.All tires will wear out faster when subjected
to high speeds as well as hard cornering, rapid
starts, sudden stops, frequent driving on roads
which are in poor condition, and off-road use.
Roads with holes and rocks or other objects
can damage tires and cause misalignment of
your vehicle. When you drive on such roads,
drive on them carefully and slowly, and before
driving again at normal or highway speeds,
examine your tires for any damage, such
as cuts, bulges, penetrations, unusual wear
patterns, etc.
TREAD WEAR INDICATORS (WEAR BARS):
Tires contain Tread Wear Indicators (Wear
Bars) in the grooves of the tire tread which
show up when only 2/32nds of an inch
(1.6mm) of tread is remaining. At this stage,
your tires must be replaced. Tires worn beyond
this stage are dangerous.
HAZARDS
Objects in the road that threaten a tire should
be safely avoided. These objects are potholes,
glass, metal, rocks, wood debris and the
like. Unavoidable contact should prompt a
thorough tire inspection.
You may not always recall hitting an object
that can damage or injure your tires. If while
driving your vehicle experiences any unusual
vibrations, ride disturbance or noise and/or you
suspect that possible damage to the tires or
vehicle has occurred, DO NOT JAM OR LOCK
YOUR BRAKES! Rather reduce your speed and
drive with caution until you can safely pull off
the road. Stop and inspect the tires. If the tire is underinflated or damaged, deflate, remove
the tire and rim assembly and replace it with
your spare. If you cannot detect a cause, have
the vehicle towed to the nearest vehicle or tire
retailer to have the vehicle inspected.
REPAIRING, MOUNTING AND
DEMOUNTING OF TIRES
Do not attempt to repair, mount or demount a
tire yourself. Tire changing can be dangerous
and must be done by professionally trained
persons using proper tools and procedures
as specified by the Rubber Manufacturers
Association (RMA). Follow these mounting
recommendations. Your tires should be
mounted on wheels of correct size and type
and which are in good, clean condition. Bent,
chipped or rusted wheels may cause tire
damage. The inside of the tire must be free
from foreign materials. Have your retailer
check the wheels before mounting new tires.
Mismatched tires and rims can explode during
mounting. Also, mismatched tires and rims can
result in dangerous tire failure on the road. If
a tire is mounted by error on the wrong-sized
rim, do not remount it on the proper rim -
scrap it. It may be damaged internally (which
is not externally visible) by being dangerously
stretched and could fail on the highway.
Old valves may leak. When new tubeless tires
are mounted, have new valves of the correct
type installed. Tubeless tires must be mounted
only on wheels designed for tubeless tires, i.e.,
wheels which have safety humps or ledges.

WORN TIRES
Never drive on worn tires. Tires should be
replaced by trained personnel when 2/32nds
of an inch tread depth remains, as indicated
by the tread wear indicators molded into the
tread grooves. In most states, it is illegal to
drive with less than 2/32nds of an inch of
tread remaining.
TIRE MIXING
For best performance select tires similar in
size and load rating to the original equipment
tires. It is recommended that the same size
and type of tire be used on all four wheel
positions. In certain tires, casing ply material
and ply construction may vary as indicated
on the sidewall of the tire. When changing
or replacing tires, it is preferred that all four
tires are the same construction type (i.e.,
High Performance, All Season, Mud & Snow)
and construction (Radial or Bias Ply). Before
mixing tires of different types on a vehicle in
any configuration, be sure to check the vehicle
Owner’s Manual for its recommendations.
Tires which meet the Rubber Manufacturer’s
Association (RMA) definition of mud and
snow tires are marked M/S, M+S, M&S. On
such tires, this designation is molded into the
sidewall. Tires without this notation are not
recommended for mud and/or snow driving.
If snow tires are needed, it is necessary
to select tires equivalent in size and load
rating to the original equipment tires.
Always fit performance snow tires in sets of four (4) for optimum mud & snow traction
and maintenance of vehicle handling
characteristics. If you do not, it may adversely
affect the safety and handling of your vehicle.
It is also important to check the vehicle
Owner’s Manual before mixing or matching
tires on 4-wheel drive vehicles as this may
require special precautions.
Please refer to your Owner’s Manual for more
information on tire replacement precautions. TIRE ROTATION
Tires on your Infiniti vehicle should be rotated
every 7,500 miles or as irregular wear
develops. If irregular wear becomes apparent
or if the wear rate on the tires is perceptibly
uneven, the tires should be rotated in such
a way to alleviate the problem. Check your
vehicle for any mechanical problems and
correct if necessary. Any rotation pattern or
procedure may be followed including those
indicated in the Owner’s Manual. Some tires
have arrows on the sidewall showing the
direction in which the tire should turn. When
rotating this type of tire, care must be taken
to maintain the proper turning direction as
indicated by the arrows. Some vehicles have
different tire sizes specified for front and rear
axles. Tires on these vehicles should not be
rotated side to side (unless they are non-
directional). Where a temporary type spare tire
is available, it should not be included in the tire
rotation schedule. Such tires are intended for
temporary use only.
REPLACING TWO TIRES
If your vehicle was originally equipped with
four tires that were the same size and you are
only replacing two of the four 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.
TRAILER TOWING
If you anticipate towing a trailer, you should
see a tire retailer for advice concerning the
correct size of tire and pressure. Tire size and
pressure will depend on the type and size of
the trailer and hitch utilized, but in no case
must the maximum cold inflation pressure or
the tire load rating be exceeded. Check the tire
decal and your Owner’s Manual for further
recommendations on trailer towing.
TIRE ALTERATIONS
Do not perform any alterations on your tires.
Alterations may prevent proper performance,
leading to tire damage, which can result in an
accident. Tires which become unserviceable
due to alterations such as truing, whitewall
inlays, addition of balancing or sealant liquids,
may be excluded from warranty coverage.
Consult your tire warranty.

HIGH PRESSURE TEMPORARY
SPARE TIRES
1) The high-pressure spare tire in your Infiniti
vehicle is designed for temporary use
only and must not be used continually as
a regular tire. The standard tire should
be repaired and/or replaced as soon as
possible.
2) Avoid driving over obstacles that may
damage the tire through impact or cutting,
such as potholes, glass, metal, etc.
3) Speed must not exceed 50MPH (80km/h) for non-speed-rated temporary spare tires.
4) Temporary spare tires have a limited
treadlife which can vary depending on road
conditions and your driving habits. The
spare tire should be returned to the trunk as
soon as the standard tire can be repaired or
replaced.
5) Because the high-pressure spare tire was specifically designed for your car, it should
not be used on any other vehicle.
6) Do not use snow chains on your high-
pressure spare. This could cause damage to
your vehicle.
7) Check the tire’s cold inflation pressure monthly and maintain at 60psi (4.2kg/cm2)
even when not in use. 8)
The high-pressure spare tire should not be
used with any other rim nor should standard
tires, wheel covers, or trim rings be used on
the high-pressure spare tire rim which was
originally installed.
9) When the tread wear indicator appears on
the tire, replace it only with the same type
spare tire.
10) Do not enter an automatic carwash with a
temporary spare tire fitted.
11) Do not make a sharp turn or apply the brakes suddenly when driving on a high-
pressure temporary spare.
Note:
When using any temporary type spare tire,
be sure to follow the vehicle Owner’s Manual
instructions.
TIRE STORAGE
All tires should be stored in a cool dry place
indoors so that there is no danger of water
collecting inside them.
When tires are stored they should be stored
in a cool place away from sources of heat
and ozone such as hot pipes and electric
generators. Be sure that surfaces on which
tires are stored are clean and free from grease,
gasoline or other substances which could
deteriorate the rubber. (Tires exposed to these
materials during storage or driving could be
subject to sudden failure.) To Avoid Damage to your Tires and Possible
Accident:
•• Check tire pressure at least once a
month when tires are cold and before
long trips.
•• Do not underinflate/overinflate.•• Do not overload.•• Drive at moderate speeds, observe legal limits.
•• Avoid driving over potholes, obstacles, curbs or edges of pavement.
•• Avoid excessive wheel spinning.•• If you see any damage to a tire, replace with spare and see the tire
manufacturer’s retailer or your Infiniti
retailer.
