Metzeler says:
Quote:Always inflate tires 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 tire pressures frequently. Correct tire pressure is crucial for safe handling. Over inflation may impair ride comfort and reduce the contact patch between the tire and driving surface of the tires. Insufficient air pressure will result in poor handling and cause a tendency for the motorcycle to "wander". In addition, improper and insufficient tire will cause accelerated tire wear, increased fuel consumption, less control and the possibilities for tire failure to due an overload/under inflated operating situation.
Recommended Minimum Tire Pressures (PSI)
Touring/Cruiser
Alpha ME880 (MH, MT, MU tires) Solo 2 Up Light 2 Up Heavy
Front 36 40 40
Rear 38 40 40
Their recommended inflation pressures are listed on this web page:
http://www.us.metzelermoto.com/web/products/tire_pressures/default.page. Of course, do not exceed the max pressure shown on the tire sidewall. I don't know what MH, MT, or MU means.
