Nothing like new shoes for your baby Relax. I am running a Sportrac 3 also, to get it to work right for me, I had to run it at 42 psi which made it wear in the middle, did you guys experience this?
I am thinking about the Yokohama Envigor when a rear is required, some seem to like them, and apparently they work well according to pictures from Mallett.
Riding single I am comfortable on lower psi , but I do mot of my riding 2 up ..
We have some speed dumps here and there , and hat is when I feel this or that.. At lower psi it feel like the shoch absorber bottoms when I have like 36 psi, and for that reason I did 42 psi on my Sportrac 3 after 2 years use.
Now, on new tires I ( And my wife sitting up) we are comfortable at 38 psi.
( I am not sure it is logic that the shock absorbers bottom earlier at lower psi, but that's how it feel like. Shock absorbers are Progressive 440. )
