3.2.1 Tire inflation pressure check
Inflation pressure
Check that the inflation pressure of a tire is 177 kPa
(1.8 kgf / cm
2
) with a pressure gauge when the tire has
cooled down. If the pressure reading exceeds the above
range, adjust the pressure accordingly.
WARNING
• Improper handling of a tire is dangerous and may cause flat tire and a rim to
come off.
• Do not work on a tire facing the rim, but from behind the tread of the tire while
checking the inflation pressure or replenishing air into a tire.
3.2.2 Checking for external injury to a tire
Check any external injury to a tire, its size and its depth
(whether it has reached the carcass or not), etc.
1) Check for any cuts on the tread.
2) Check for any cracks on a rim or deformation of rim
flanges.
When a tire shows one or more of the following
conditions, regard it as defective, and replace the tire with
a new one for safety.
1) When the bead wire is cut, bent or significantly deformed
2) When the carcass ply is showing due to excessive wear
3) When damaged portion of the carcass exceeds one thirds of the tire width
4) When a tire has ply separation (peeling)
5) When radial cracks reach the carcass
6) When the tire is not regarded as durable due to abrasion, deformation, or abnormal flaw
growth.
Please consult with an agency for maintenance in the following cases.
• When injury is found on the surface of a tire.
• When the degree of wear on the front, rear, right and left sides of a tire are extremely
different.
