TYPES OF TIRES
WARNING
.When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or Snow)
andconstruction. An INFINITI dealer may
be able to help you with information
about tire type, size, speed rating and
availability.
.Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
.Replacingtires with those notoriginally
specified by INFINITI could affect the
proper operation of the TPMS.
.For additional information regarding
tires, refer to “Important Tire Safety
Information”(US) or “Tire Safety Infor-
mation”(Canada) in the Warranty In-
formation Booklet.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions.All Season tiresare identified by ALL
SEASON and/or M&S (Mud and Snow) 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
modelsto provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating M&S on the tire sidewall.
Ifyou 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 handling of your vehicle.
Generally,snow tires will have lower speed
ratings 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
pattern on all four wheels.
For additional traction on icy roads,
studdedtires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of
studdedsnow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.
TIRE CHAINS
Use of tire chains may be prohibited
accordingto location.Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
propersize for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class “S”chains are used
on vehicles with restricted tire to vehicle
clearance.Vehicles thatcan use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
thetire and the closest vehicle suspension
or body component required to accommo-
datethe use of a winter traction device (tire
chainsor cables).The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chaintensioners when recom-
