Tyre Wear; Minimum Recommended Tread Depth - Triumph Rocket 3 TFC 2020 Owner's Handbook Manual

Maintenance
Tyres and inner tubes that have been
used on a rolling road dynamometer
may become damaged. In some cases,
the damage may not be visible on the
external surface of the tyre.
Tyres and inner
replaced after such use as continued
use of a damaged tyre or inner
tube may lead to instability, loss of
motorcycle control and an accident.

Tyre Wear

As the tyre tread wears down, the tyre
becomes more susceptible to punctures
and failure. It is estimated that 90%
of all tyre problems occur during the
last 10% of tread life (90% worn). It is
recommended that tyres are changed
before they are worn to their minimum
tread depth.
