WHEEL ALIGNMENT AND BALANCING
Wheel alignment and balancing are important for safety
and maximum mileage from your tires. Check how your tires
are wearing at least once a month. If your tires are wearing
unevenly, such as the inside shoulder of the tire wearing
faster than the rest of the tread, or if you detect excessive
vibration, your vehicle may be out of alignment or balance.
These conditions not only shorten the life of your tires, but
adversely affect the handling characteristics of your vehicle
which could be dangerous. If you detect irregular wear or
vibration, have your alignment and balance checked imme-
diately. 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 becomes
thinner 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 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 con-
struction (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 recommen-
dations.
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 ismolded 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 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 informa-
tion 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 differ-
ent 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.

IMPORTANT TIRE SAFETY INFORMATION153

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 acci-
dent and personal injury.
TRAILER TOWING
If you anticipate towing a trailer, you should see a tire
dealer 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 dam-
age, which can result in an accident. Tires which be-
come 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 Nissan
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 stan-
dard tire can be repaired or replaced.
5) Because the high-pressure spare tire was spe-
cifically 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 tem-
porary spare tire fitted.
11) Do not make a sharp turn or apply the brakes
suddenly when driving on a high-pressure tem-
porary spare.
Note:When using any temporary type spare
tire, be sure to follow the vehicle Own-
er’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.)
