Checking Wear Situations Of Thread - Benelli TNT 25 Maintenance Manual

Checking Wear Situations of Thread

As the tread wear is more and more serious, it is more likely to
cause tire blowout. It is estimated that 90% of tires will be damaged
in the last 10% of service life of tire (90% wear). If the tire is used
until it is grinded smoothly, the money cannot be saved and safety
issues may be caused.
●Measure the tread depth in the middle of the tread with a depth
meter [A]. As the tire is worn unevenly, the measurement shall be
carried out in different parts.
★If any value measured are below the service limit, the tire must be
replaced (see "Disassembling/ Installing Tire" in the "Wheel/Tire"
chapter).
