Always inflate tyres to the correct pressure as indicated in the owner's manual. However Metzeler North America has found the air pressure suggestions listed below will improve mileage and customer satisfaction especially if a emphasis is placed on running the air pressure towards the maximum as stated on the sidewall. Check cold tyre pressures frequently. Correct tyre pressure is crucial for safe handling. Over inflation may impair ride comfort and reduce the contact patch between the tyre and driving surface of the tyres. Insufficient air pressure will result in poor handling and cause a tendency for the motorcycle to "wander". In addition, improper and insufficient tyre will cause accelerated tyre wear, increased fuel consumption, less control and the possibilities for tyre failure to due an overload/under inflated operating situation.
