Tyres - Check For Wear/Damage

Warning - General - Stabilise Motorcycle - including DO NOT support on non integral parts

warning
Make sure the motorcycle is stabilised and adequately supported.Do not support the motorcycle on any ancillary component, the exhaust system or any other non structural parts of the motorcycle frame.A correctly supported motorcycle will help prevent it from falling.Failure to follow the advice above could result in serious injury or death.

Warning - Tyre Safety Fragment

warning
Operation with excessively worn tyres is hazardous and will adversely affect traction, stability and handling which may lead to loss of control and an accident.When tubeless tyres, used without a tube, become punctured, leakage is often very slow. Always inspect tyres very closely for punctures. Check the tyres for cuts, embedded nails or other sharp objects. Operation with punctured or damaged tyres will adversely affect motorcycle stability and handling which may lead to loss of control or an accident.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 authorised Triumph dealer for tyre replacement, or for a safety inspection of the tyres.

As the tyre tread wears down, the tyre becomes more susceptible to puncture and failure. It is estimated that 90% of all tyre failures occur during the last 10% of tread life (90% worn). It is false economy and unsafe to use tyres until they are worn to their minimum.

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.

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 tyres for cracks, splits and kerb damage. Always replace tyres that are suspected of having become damaged.

Damaged tyres must be replaced.
