Something is wrong, I weigh more, ride really bad roads and do not get pinch flats even when I nail things really hard. Something stinks here********** are you using a wide rim with your narrow tires? Even though they will fit you widen the profile at the bead and functionally reduce the road to rim distance.
I have a set of go fast wheels that I add to my t-2000 touring bike. My easton circuits with 23's and a small block are a fast fun ride. I do not think I would put my Pro-max tires on my touring rims. Check your rim width.
