WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may resu lt in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward.
(  P. 456) Installing the nuts with th e tapered ends facing outward can
cause the wheel to break and ev entually cause the wheel to come off
while driving, which could lead to an accident resulting in dea th or seri-
ous injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing
an accident.
