Scrubby, you ask a very interesting question. Pls let us know what the sticker on your swing arm calls for.
My '07 wee showed 33F/36R solo and 33/41 2-up. I think in 2009 the DOT stopped manufacturers from listing different pressure for different loads. The sticker had to show only the presure required to carry the max load, 'cuz too many consumers don't deal well with conditionals. My '14 Vee2 shows 36/41 for all conditions. I'm running 36/39 (solo) and really like how it handles. Nothing wrong with higher pressures, but maybe they aren't optimal. Among other things, tires need to be normally warm for best traction. Tires warm mainly by flexing, and flexing is controlled by both load and the air pressure. A bit less pressure in cold weather and a bit more in hot weather has some things to recommend it. Some people will say that the pressure on the side wall is the required pressure (not true), and some will say that this max pressure gives better tire life. Maybe, but at the cost of perhaps less traction and a harsher ride.
So...start with the swingarm sticker pressure, but be open to some reasonable experimentation.
How well does my Vee2 handle at 36/39? Yesterday I was riding a fun road (Washington's SR-112) which has some Slow To 15 and Slow to 20 curves. Once I set the radius in the curves, I could have let go of the grips and the bike held its radius around the curve. Your bike weighs a little less, so a bit lower pressures will work well for you. My favorite NoCal road?...US-199 is a good one.
And, let us know how you like the T30s.
