Please check if there are any cracks and damages
such as wears on one side, partial wares, step-shaped
wares, nails and stones stuck or cut into the tires on
the contacting surfaces with the grounds, both side
surfaces and all around of the tires. If you find any
abnormal conditions, replace tires.
2) Check air pressures.Check air pressures with tire
gauges when tires are cool enough, and make certain
that they are at 137.3 kPa {20psi}. Adjust air pressures
of the tires if they are NOT appropriate.
3) Check whether or not the wheel nuts are loose. Check
if the wheel hub nuts are loose or fallen off or if wheel
hub bolts are broken. Also check if there are any rust
fluids and/or whether or NOT the lengths of all the
wheel hub bolts projected out of the wheel hub nuts are
the same.
Check the wheel hub nut for looseness. If it is loose,
tighte’n it. Be sure to torque it to the specified value.
