'fraid you're reading the chart wrong, Greg... the bottom (horiz.) scale is WHEEL LOAD, not total weight...
Granted, it still doesn't go high enough for ME, but...... being a linear-looking relationship, it's easy to extrapolate...
I'm not sure what a B-brand hiracer load distribution is, but it's probably about 60 (rear) :40 (front). The Stratus XP is ~ 67:33, and the Xstream is closer to 75:25.
So if combined rider/stuff/bike weight is ~245 pounds and you're on 28mm tires on a 60:40 hiracer, the chart indicates 110 psi for the rear tire (~145 pounds), and ~75psi on the front (~100 pounds)...
On the other hand, if you're Jay on the XStream on 25mm tires, tipping the total scale at MAYBE 150 pounds combined, he should be running 85 psi on the rear, and no pressure whatsoever on the front...
