replacing these tires. NISSAN recom-
mends that tire replacement be per-
formed at a GT-R certified NISSAN
dealer.
. Specific tire changing equipment must
be used to remove the GT-R tires from
the wheel and to install the GT-R tires
onto the wheel. It is only possible to
reuse the tires when they have no
cracks and/or deformations on the
bead portion of the tire. If the incorrect
equipment is used to remove the GT-R
tires from the wheel and to install the
GT-R tires onto the wheel, cracks and
deformation may occur on the bead
portion of the tires meaning that the
tires cannot be reused. Contact a GT-R
certified NISSAN dealer if the tires
need to be removed from the wheels.
