If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies All Season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than All Season
tires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
“M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire.
If you install snow tires, they must be the
same size, brand, construction and tread pat-
tern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/55R20 size tires. Installation of the
tire chains/cables on 235/55R20 size tires
will cause damage to the vehicle. If you plan
to use tire chains/cables, you should install
235/65R18 size tires on your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size for
the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions. Use only SAE class “S” chains. Class
“S” chains are used on vehicles with restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the
minimum clearances between the tire and the
closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined us-
ing the factory equipped tire size. Other types
may damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end
links of the tire chain must be secured or
removed to prevent the possibility of whip-

Spare tire (TEMPORARY USE
ONLY spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be dam-
aged or involved in an accident:
WARNING
∙ The spare tire should be used for emer-gency use only. It should be replaced with
the standard tire at the first opportunity
to avoid possible tire or differential
damage.
∙ Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
∙ Periodically check spare tire inflation pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 420 kPa, 4.2 bar (60 psi).
∙ With the TEMPORARY USE ONLY spare tire installed do not drive the vehicle at
speeds faster than 50 mph (80 km/h). ∙ When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used on
the front wheels (drive wheels).
∙ Tire tread of the TEMPORARY USE ONLY spare tire will wear at a faster rate
than the standard tire. Replace the spare
tire as soon as the tread wear indicators
appear.
∙ Do not use the spare tire on other vehicles.
∙ Do not use more than one spare tire at the same time.
∙ Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.
CAUTION
∙ Do not use tire chains on a TEMPORARYUSE 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.
