Always ensure that both front and rear tyres are correctly inflated and check tyre pressure regularly. Tyre pressure has a direct influence on the performance and wear of your tyres.
Always keep the motorcycle manufacturer's recommended air pressure in both tyres. This is an important requirement for tyre safety and mileage. Your motorcycle owner’s manual will tell you the recommended cold inflation pressure. On some motorcycles, the recommended front and rear tyre pressures will be different. The pressures stamped on the sidewall of the tyre are only for maximum loads. On some occasions, these pressures will also be the manufacturers recommended settings as well.
Riding on tyres with too little air pressure is dangerous. The tyres will build excessive heat which can cause a sudden tyre failure that could lead to serious personal injury or death.
Underinflation may also:
- Damage the tyre leading to tyre failure
- Adversely affect vehicle cornering
- Reduce tyre life
- Increase fuel consumption
- Fatigue cracking
Riding on tyres with too much air can also be dangerous. The tyres are more likely to be cut, punctured, or broken by sudden impact. Serious personal injury or death could result. Do not exceed the pressure indicated on the tyre sidewall. Consult your owner’s manual for the recommended inflation pressure.
Never inflate a tyre unless it is secured to the motorcycle or a tyre-mounting machine. Inflating an unsecured tyre is dangerous. If it bursts, it could be hurled into the air with explosive force resulting in serious personal injury or death.
Checking Tyre Inflation
Check your tyre air pressure at least once a week and before long trips. Be sure to use an accurate pressure gauge.
Check your air pressure when the tyres are "cold." The tyres are "cold" when your motorcycle has been ridden less than a mile at moderate speed or after being stopped for three or more hours.
If you must add air when your tyres are hot, add 0.28 bar / 4 p.s.i. above the recommended cold inflation pressure. Recheck the inflation pressure when the tyre is cold.
Never release air from a hot tyre in order to reach the recommended cold tyre pressure. Normal riding causes tyres to run hotter and inflation pressure to increase. If you release air when your tyres are hot, you may dangerously under inflate your tyres.
If your tyres lose more than 0.14 bar / 2 psi per month, the tyre, the valve, or wheel may be damaged. Consult your local dealer for an inspection.
Valves and Valve Caps
Old or damaged valves may cause air loss. Replace them when mounting new tyres. Use valve caps (finger tight) to keep dust, dirt and moisture away from the valve and to help guard against air leakage.
