four wheel drive NISSAN LEAF 2014 1.G Warranty Booklet

Any tire, no matter how well constructed, may fail due to
improper maintenance or service factors. This could
create a risk of property damage and serious or fatal
injury. Disregarding any of the safety precautions and
instructions contained in this manual may result in tire
failure or explosion causing serious personal injury or
death. For your safety, comply with the following:
TIRE INFLATION
Keep tires inflated to the pressures recommended on
the tire data placard. (See your OWNER’S MANUAL for
location.) These inflation pressures must be maintained
as a minimum. However, do not exceed the maximum
pressure rating indicated on the tire sidewall.
CHECK INFLATION PRESSURES ON ALL YOUR
TIRES, INCLUDING THE SPARE, WHEN TIRES ARE
COLD, AT LEAST ONCE A MONTH BEFORE DRIV-
ING.
Failure to maintain correct inflation may result in im-
proper vehicle handling and may cause rapid and ir-
regular tire wear, sudden tire destruction, loss of vehicle
control and serious personal injury. Therefore, inflation
pressures should be checked at least once a month and
always prior to long distance trips.
Pressures should be checked when tires are cold. The
tires are cold when your vehicle has been driven less
than a mile at moderate speed after being stopped for
three or more hours.
CHECKING PRESSURE WHEN TIRES
ARE HOT
If you must add air when your tires are hot, add four
pounds per square inch (psi) (28 kPa) above the rec-
ommended cold air pressure. Recheck the inflation
pressure when the tire is cold.
For Example Only:
Gauge reading of hot tire: 32 psi
If recommended pressure is: 30 psi
Desired gauge reading of hot tire 30+4psi=34psi
Check cold pressures as soon as possible, at least by
the next day. Never “bleed” air from hot tires as your tire
will be underinflated. Use an accurate tire gauge to
check pressures. Never allow children to air up tires.
DRIVING ON ANY TIRE THAT DOES NOT HAVE THE
CORRECT INFLATION PRESSURE IS DANGEROUS.
For replacement tires, the correct inflation pressure will be
provided by your tire dealer. If not, refer to the vehicle decal.
Underinflation produces extreme flexing of the sidewalls
and builds up heat which may result in sudden tire de-
struction and serious personal injury. Overinflating can
cause the tire to be more susceptible to impact damage.
LOAD LIMITS
DO NOT OVERLOAD. DRIVING ON ANY OVER-
LOADED TIRE IS DANGEROUS.Never load your
tires beyond the load carrying limits molded into the
sidewall of the tires or the maximum vehicle load limit as
shown on the vehicle tire data placard, whichever is
less. Overloading causes heat to build up which can
lead to sudden tire failure and serious personal injury.
SPEED LIMITS AND SPEED RATED
TIRES
HIGH SPEED DRIVING CAN BE DANGEROUS.
Never operate your vehicle in excess of lawful speeds or
the maximum speeds justified by the driving conditions.
Excessive speeds or racing can cause heat buildup in a
tire leading to possible failure and serious personal
injury.
Correct inflation pressure is especially impor-
tant. However, at high speeds, even with the correct
inflation pressure, a road hazard, for example, is more
difficult to avoid and if contact is made, there is a greater
chance of causing tire damage than at the lower speed.
Moreover, driving at high speed reduces the reaction
time available to avoid accidents and bring your vehicle
to a safe stop. If you see any damage to a tire or wheel,
replace it with your spare tire and see your tire dealer at
once.
Tire speed ratings do not imply that a vehicle can be
safely driven at the maximum speed for which the tire is
rated. In addition, some damages or improper repairs
may cause a speed-rated tire to lose its speed rating.
Exceeding the tire’s maximum speed rating will cause
the tire to build up excessive heat which can cause tire
damage that could result in sudden tire destruction and
rapid air loss. Failure to control a vehicle with sudden air
loss can lead to an accident. In any case, you should not
exceed reasonable speeds as indicated by the legal
limits and driving conditions.

IMPORTANT TIRE SAFETY INFORMATION121

acteristics of your vehicle which could be dangerous. If
you detect irregular wear or vibration, have your align-
ment and balance checked immediately. Tires which
have been run underinflated will show more wear on the
shoulders than in the center of the tread.
HARD BRAKING
You must inspect your tires after any hard braking cir-
cumstances or after tires have slid on the pavement.
This can cause a flat spot in a section of the tire tread.
TIRE SPINNING
Never spin your tires above a speedometer reading of
35 mph (55 km/h) if your vehicle becomes stuck. The
centrifugal force generated by the free spinning
tire/wheel assembly may cause a sudden tire explosion,
resulting in vehicle damage and/or serious personal
injury or death. Never allow anyone to stand near or
behind a tire spinning at high speed while attempting to
push a vehicle that is stuck. When in mud, sand, snow,
ice or other slippery conditions, do not indulge in exces-
sive wheel spin. In such conditions, with automatic
transmission vehicles, by accelerating the engine ex-
cessively, it is possible to spin one of the drive tires
beyond its speed capability. This is also true when
balancing a drive tire/wheel assembly using the engine
of the vehicle to spin the wheel.
TIRE TREAD
Tires must be replaced when the depth of the tread
reaches 2/32 inch (1.6 mm) . Tires are manufactured
with tread wear indicators molded into the tire grooves
which indicate tread wearout. As tires approximate
2/32 inch (1.6 mm) wearout, the tread gauge becomesthinner and more vulnerable to the effects of road haz-
ards. Also, worn tires are more subject to hydroplaning,
which can cause loss of control. Therefore, visual tire
inspection becomes more crucial as the tires wear out.
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 recom-
mended 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 Associa-
tion (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 equip-
ment tires. Always fit performance snow tires in sets of four (4) for optimum mud & snow traction and mainte-
nance 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 OWN-
ER’S MANUAL before mixing or matching tires on
4-wheel drive vehicles as this may require special pre-
cautions.
Please refer to your OWNER’S MANUAL for more
information on tire replacement precautions.
TIRE ROTATION
Tires on your Nissan 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 tem-
porary type spare tire is available, it should not be
included in the tire rotation schedule. Such tires are
intended for temporary use only. Whenever only two
tires are replaced, the new tires should be put on the
rear axle of vehicles equipped with the same size tire on
all four wheel positions.
