Checking your tyre pressure is the most important type of tyre maintenance. Check cold tyre pressure frequently with a good-quality gauge on a weekly basis.
Underinflated tyres can result in imprecise cornering, higher running temperatures, irregular tread wear, fatigue cracking, overstressing and eventual failure of the tyre carcass, or loss of control, which could cause accident, injury or death. Overinflating tyres does not increase load-carrying capacity, but will result in a harsh ride and accelerated tyre wear in the centre of the contact patch.
Keep in mind that hard cornering, passengers, heavy loads and sustained high speeds will require higher pressures (up to that indicated on the sidewall). For high-speed, fully loaded or dual-riding touring-motorcycle applications, inflate tyres to maximum recommended by vehicle manufacturer, if applicable.
Never exceed maximum load indicated on tyre sidewall or vehicle capacity load found in owner’s manual, whichever is lower.
Loss of pressure may occur due to worn-out or badly seated valve cores. Check valve cores, and if necessary, tighten for correct seating, or remove and replace them. A metal or hard-plastic valve cap with an inner gasket should be used and installed finger-tight to protect the valve core from dust and moisture and to help maintain a positive air seal.
When replacing tyres, always inspect rim bands, tubes and valves. Replace if damaged or cracking is noted.
Repeated loss of inflation pressure may result from undetected tyre damage. Visually inspect tyres for punctures, cuts, abrasions, cracks, bulges, blisters or any other damages. The appearance of stress cracks in the tread grooves is one indicator of overload and/or underinflation. If you find evidence of tread-groove cracking, you should remove and replace the tyre immediately. This damage is permanent and non-repairable.
Damage caused by impacts, penetrations or continued underinflated/overloaded use is progressive and can result in sudden and complete tyre failure and accident, injury or even death. Always seek expert inspection of the dismounted tyre following curb, pothole or other impacts, evidence of penetration beyond the tyre surface, bulges or low pressure. Do not continue riding on such tyres. Inspect your tyres frequently for damage and always heed warning signs such as vibration, handling instability, rubbing or tyre noise that occurs during operation of your bike.
