Follow pressure recommendations shown on the Dunlop Motorcycle Tire Application Guide. Contact Dunlop if year and model are not shown on the current guide and the ownerâ€s manual does not list pressure settings
for Dunlop tires.
Keep in mind that hard cornering, passengers, heavy loads and sustained high speeds will require higher pressures (up to that indicated on the sidewall).
CHECKING TIRE PRESSURE IS THE MOST IMPORTANT TIRE MAINTENANCE FUNCTION YOU AND YOUR CUSTOMER CAN PERFORM.
For high-speed, fully loaded or dual-riding touring-motorcycle applications, inflate tires to maximum recommended by vehicle manufacturer for Dunlop fitment. Never exceed maximum load indicated on tire sidewall or
vehicle capacity load found in ownerâ€s manual, whichever is lower.
Underinflated tires can result in imprecise cornering, higher running temperatures, irregular tread wear, fatigue cracking, overstressing and eventual failure of the tire carcass, or loss of control, which could
cause accident, injury or death.
Overinflating tires does not increase load-carrying capacity, but will result in a hard ride and accelerated tire wear in the center of the contact patch.
Advise your customers to check cold tire pressure frequently with a good-quality gauge that holds a reading, and always before extended trips.
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.
Loss of pressure may also be caused by tube damage, as well as cracked rubber tube or tubeless valve stem bases. Inspect rim bands, tubes and valves. Replace if damage or cracking is noted.
Repeated loss of inflation pressure may result from undetected tire damage. Visually inspect tires for punctures, cuts, abrasions, cracks, bulges, blisters or knots. It will be necessary to dismount the tire to
complete an inspection for internal damage and any need for repair. See the Tire Repair section. Only certain punctures in the tread area may be repaired, and only if no other damage is present.
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 tire immediately. This damage
is permanent and non-repairable.
Tires with non-repairable damage must not be used again (see Tire Repair). Damage caused by impacts, penetrations or continued underinflated/overloaded use is progressive and can result in sudden and complete tire
failure and accident, injury or death.
Your customers should always seek expert inspection of the dismounted tire following curb, chuckhole or other impacts, evidence of penetration beyond the tire surface, bulges or low pressure. They should not continue
riding on such tires.
Advise your customers to inspect their tires frequently for damage and to always heed warning signs such as vibration, handling instability, rubbing or tire noise that occurs during operation of the motorcycle.
