i have a 2005 Royal Star Tour Deluxe with a Venture Tour Pack and Quadzilla Fairing.  My wife and I each weigh about 190.  I currently have Metzler ME880s on front and rear.   
Front size 130/90-16 M/C 67H 
Rear Size 150/90 B 15 M/C 80H 
Front Pressure 38 psi 
Rear Pressure  46 psi   
I have been having problems with the tires cupping.   
Question #1  What Tire Pressures are people running on the second Gens to prevent cupping? 
Question #2  I am considering giving the Michelin Commander IIs a try.  Has anyone tried these, and what are your opinions of these tires compared to other tires such as Dunlop EIIIs, Metzler 880s, etc.  Is there a consensus on what the tire of choice is for second gens?   
Thanking you in advance for your feedback.   
Regards, 
Tony
