GTR-18 GT-R Overview
WARNING
Keep your tires inflated to the correct
tire pressure. Driving with low tire
pressure can damage some powertrain
systems and affect the operation of the
ABS and VDC systems. Low Tire pres-
sure may also cause tire failure and
result in serious personal injury or
death.
. Make sure the tire valve stem cap is installed
and that the valve stem is tight. When
installing the cap, make sure to tighten the
cap by hand. If a tool is used to tighten the
cap, the cap may be damaged.
. Make sure the wheel nuts are tight.
( “Wheels and tires” page 8-32)
. Make sure the drive shaft nuts are tight.
. Make sure to replace the grommet seal, the
valve core and the valve cap of the Tire
Pressure Monitoring System (TPMS) sensor
attached to the wheel every 3 years for
performance driving use. Replace them
every 5 years even when not engaging in
performance driving. A dirty grommet seal
will cause the air leak from the tire.
. Make sure that the nuts and valves that are
attached to the TPMS sensor are tight and
there is no nitrogen leak.
. Use only a NISSAN genuine valve cap or
equivalent.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check
these with the tires removed whenever an
inspection is performed with the vehicle
jacked up.
. Secure road wheel balance weights with
aluminum tape.
. Check that the wheel nuts are not stripped.
. Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires.
. Avoid the driving conditions listed under
“Additional maintenance items” in this sec-
tion for 48 hours after tires are installed on
