INSPECTION AND ADJUSTMENTS OF TIRES,
SUSPENSION, CLUTCHES AND BRAKES
The information and specifications below apply only when
engaging in performance driving.
● Measure and adjust (if needed) the wheel alignment.
● Check tire wear.
● Check the tire pressure and adjust the pressure as
necessary when the tires are cold. Refer to GT-R
Owner’s Manual.
● Make sure the tire valve stem cap is installed and that
the valve stem is tight.
● Make sure the wheel nuts are tight.
● Make sure the drive shaft nuts are tight.
● Secure road wheel balance weights with aluminum
tape or equivalent.
● 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 rebalanced. Make sure the old
reference marks are erased and new reference marks
are applied to the wheel and tire. When installing new
tires on the wheels, make sure new reference marks are
applied to the wheels and tires.
● Check for the heat deterioration of the brakes and
parts around the brakes. NISSAN recommends that
the brakes should be bled before engaging in perfor-
mance driving and when replacing the brake fluid. It is
recommended that bleeding the brakes be performed
when the brake calipers are hot [about 212°F (100°C)]
● Check around the engine, transmission, differential
and under the vehicle for oil and coolant leaks.
● Before engaging in performance driving, the clutch
clearance may need to be adjusted. See your GT-R
certified NISSAN dealer for information. NOTICE: Fail-
ure to have the clutches properly adjusted before per-
formance driving may cause the transmission oil tem-
perature to increase which may cause transmission
damage.
● Check the steering and suspension system and other
links for loose and/or damaged parts before and after
driving.
