Tire wear and damage
WARNING
O Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.
O The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
O Tires degrade with age and use.
Have tires, including the spare,
over6yearsoldcheckedbya
qualified technician, because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
O Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an INFINITI
dealer.
O For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Informa-
tion Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
speed rating and load carrying capacity
as originally equipped. See “Specifica-
tions” in the “9. Technical and consumer
information” section for recommended
types and sizes of tires and wheels.
WARNING
O The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.
O If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased
