Tyre Wear; Minimum Recommended Tread Depth - Triumph Sprint ST Owner's Handbook Manual

Maintenance and Adjustment

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 to use tyres until they are
worn to their minimum.
Minimum Recommended Tread
Depth
In accordance with the periodic maintenance
chart, measure the depth of the tread with a
depth gauge, and replace any tyre that has
worn to, or beyond the minimum allowable
tread depth specified in the table below:
Under 130 km/h 2 mm (0.08 in)
(80 mph)
Over 130 km/h Rear 3 mm (0. 1 2 in)
(80 mph) Front 2 mm (0.08 in)
