2018 INFINITI QX30 snow chains

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 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
pattern 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.
Four-Wheel Drive (4WD) models
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.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/45 R19 or 235/50 R18 size tires.
Installation of the tire chains/cables on
235/45 R19 or 235/50 R18 size tires will
cause damage to the vehicle. If you plan to
use tire chains/cables, you should install
215/60 R17 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 that they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s in-
structions.
Use chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chains must be
secured or removed to prevent the possibility
of whipping action damage to the fenders or
underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
8-32Do-it-yourself

Never install tire chains on a T-type spare tire
(TEMPORARY USE ONLY).
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains
in such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress.

TIRE WEAR AND DAMAGE
WARNING
•Tires should be periodically inspected
for wear, cracking, bulging or objects
caught in the tread. If excessive wear,
cracks, bulging or deep cuts are found,
the tire should be replaced immediately.
•The original tires have a built-in tread
wear indicator. When the wear indicator
is visible, the tire should be replaced.
•Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician be-
cause some tire damage may not be ob- vious. Replace the tires as necessary to
prevent tire failure and possible per-
sonal injury.
•Improper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, it is
recommended that you visit an INFINITI
retailer for this service.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Tires should be periodically inspected for
wear, cracking, bulging or objects caught in
the tread. If excessive wear, cracks, bulging
or deep cuts are found, the tire should be
replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in se-
rious personal injury. If it is necessary to re-
pair a tire, it is recommended you contact an
INFINITI retailer.SDI1663Z
