All tyres are fitted with tread wear indicators. When the tyre becomes worn down as far as the top of a tread wear indicator, the tyre is worn beyond its service life and must be replaced. Attention must also be paid to the legal limits for tread wear, which differ from country to country. Tyres that have worn to the legal limit in the country or region in which the motorcycle is operated must be replaced, even if tread wear has not yet reached the level of the tread wear indicators.
In accordance with the scheduled 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.
Inspect wheels for cracks, splits and kerb damage. Always replace wheels that are suspected of having become damaged.
Warning!
- Operation with excessively worn tyres is hazardous and will adversely affect traction, stability and handling which may lead to loss of motorcycle control or an accident.
- When tubeless tyres become punctured, leakage is often very slow. Always inspect tyres very closely for punctures. Check the tyres for cuts, imbedded nails or other sharp objects. Check the rims for dents or deformation. Operation with damaged or defective wheels or tyres is dangerous and loss of motorcycle control or an accident could result. Always consult your Triumph dealer for tyre replacement, or for a safety inspection of the tyres.
Minimum recommended tread depth
In accordance with the scheduled maintenance chart, measure the depth of the tread with a depth gauge, and replace any tyre that has worn to, or beyond the minimum legally allowable tread depth.
In countries where there is no legal minimum tread depth, Triumph recommends the following;
| Speed | Minimum Tread Depth |
| Under 130 km/h (80 mph) | 2 mm (0.08 in) |
| Over 130 km/h (80 mph) | Rear 3 mm (0.12 in) Front 2 mm (0.08 in) |
Warning! Triumph motorcycles must not be operated above the legal road speed limit except in authorised closed course conditions.
Warning! Only operate this Triumph motorcycle at high speed in closed-course on-road competition or on closed course race tracks. High speed operation should only then be attempted by riders who have been instructed in the techniques necessary for high speed riding and are familiar with the motorcycle's characteristics in all conditions. High speed operation in any other circumstances is dangerous and may lead to loss of motorcycle control and an accident.
