*Some V (or VR) rated tires may have a speed capacity
of greater than 149 mph (240 km/h). Consult your tire
manufacturer for maximum speed ratings if your vehicle
capability exceeds this speed.
**Z (or ZR) rated tires are designed for use on cars with
maximum speed capabilities in excess of 149 mph
(240 km/h). Consult your tire manufacturer for maxi-
mum speed capabilities.
†Although a tire may be speed rated, we do not endorse
the operation of any vehicle in an unsafe or unlawful
manner. Speed ratings are based on laboratory tests
which relate to performance on the road, but are not
applicable if tires are underinflated, overloaded, worn
out, damaged, altered, improperly repaired, or re-
treaded. Furthermore, tire speed ratings do not imply that vehicles can be safely driven at the maximum speed
for which the tire is rated, particularly under adverse
road and weather conditions or if the vehicle has un-
usual characteristics. Most highway passenger tires that
do not have a speed symbol in the sidewall have a
maximum speed rating of 105 mph. Light truck highway
tires that do not have a speed symbol on the sidewall of
the tire have a maximum speed of 87 mph. Some light
truck tires may have higher maximum speeds; consult
your tire retailer. The speed and other ratings of re-
treaded tires are assigned by the retreader and voids the
original manufacturer’s ratings.
IMPORTANT:
In order to maintain the speed capability
of the vehicle, replacement tires must have speed rat-
ings equal to or higher than those fitted as original
equipment (as indicated on the vehicle placard or Own-
er’s Manual). If tires with lower speed ratings are fitted,
the speed capability of the vehicle will be lowered to the
maximum speed capability of the replacement tire as
indicated on the above table.
Remember...High speed driving can be dangerous and
may be damaging to your tires.
And...When driving at highway speeds, correct inflation
pressure is especially important.
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 por-
tion of the tire without being
visible onthe outside. If
damage can be seen on the tires or wheels, or if you
suspect that possible impact damage may have oc-
curred, 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 in-
specting 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 dam-
age 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 con-
dition, 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.

IMPORTANT TIRE SAFETY INFORMATION139

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 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 liq-
uids, may be excluded from warranty coverage. Consult
your tire warranty.
HIGH PRESS URE TEMPORARY SPARE TIRES
1) The high-pressure spare tire in your Infiniti ve-
hicle 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, g lass,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 origi-
nally 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.)
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 .
