I don't know why Michelin does not put this information on their web site. I called them, 800-346-4098, and this is a summary of what they said.

Solo: Front 32 psi and rear 36 psi
Loaded: Front 36 psi and rear 42 psi

Michelin's representative said to use these pressures. There is also a version of the Pilot Road 3 with a "B" rating.
It means the sidewall is stiffer for two-up riding. Standard is for single riding. The load rating is the same but the stiffer sidewall will help the tire stay round when two-up. They will both last the same mileage.

I think it also makes a difference whether you're Karen (Mrs Membership) or Chiba, for example. For the former, I'd say use the 32psi and 36psi recommendation. For the latter, a bit more, I think. Point is, there's no absolutely correct single recommendation for everybody. We should each do what makes sense to us, check ride, handling, and wear, and adjust if needed.

(I observed that Nate used 18psi F and R on his old boxer S's, for max traction. Of course, he went through them really fast.)

Silver, the "cool and aloof" color.

Gold, the "paying the restorer" color.

Those pressures make a lot more sense to me. I think I'll let some air out of my tires, (maybe 34/40 or 36/40) and see how they do...I've always thought things were a bit harsh going over bumpy roads. :x Perhaps that's why :?: Though I've never thought a couple of pounds would make that much difference in either handling or ride quality. I have no idea what it would do to wear, though. The weight of the bike goes up and down significantly just by riding it and using fuel :!:

I run 39 on the front and 42 on the rear and try to check them frequently. I just swapped out a set of tires with 15,000 miles on them. I had a 2,000 mile trip coming up and knew I could not have gotten through the trip with those tires. If I had been doing local rides I may have kept them on longer. I really like the way the PR3's handle in all kinds of weather. I think I swap them 3 times this year and each time I kept getting the interval longer and longer.

What bike are you riding, Don? I've been running at 40/42, but lately I keep thinking I'm detecting a bit of slipage. Running a bit softer (down to 36/40, perhaps) would prevent that feeling, since they're not even close to worn out.

Bike is a 2009 R1200RT - I have not noticed any slippage at 39/42.
