I'm right at 193 to 195 lbs and will usually have approx. 15 to 18 lbs of riding gear on....leather suit, helmet, gloves, boots, etc and pretty much run 30/30 in most of the tires that I ride on the street bikes. A couple of exceptions are my ST1300 that I run the Pilot Road III front and rear. That one is usually right at 41 to 42 psi cold, ...BUT, that bike is rode two up about 99% of the time, with a top box and loaded side bags, so it's approaching a close to capacity load. The other exception is my track bike. I don't have a lot of experience with a lot of different tires brands, but I've got a ton of experience with most of the Michelin products...from the full blown race tires (Power Cup Competition) to the Pilot Road III, and somewhere around 30 psi cold pressure will work pretty well to make a tire stick on the street. As I said, I don't commute or spend a lot of time on the highways....most of my riding is done in the mountains, so stickiness is my most urgent concern. As far as the rear shock goes, try to get your rear loaded sag set somewhere in the 35 to 38mm range, that should be a good start for you.
