OP, if I were you, I'd look to use 28c tires at 90 psi (if those will fit your frames). Also, run your fingers thru the rim hook just to make sure there is not rough spot that could puncture the tube (very lightly sand down any rough spot using fine grained sandpaper). On a related note, you would have been better off getting the Zipp 30 Course wheelset as they are a tad heavier and built more for the CX/gravel applications (which works out great for clydes on the road). I use these Zipp Course 30 wheels, with 25c tires, and I weigh under 130 lbs, and I use 80 psi for the rear, 75 psi for the front. Any lower psi then the tires feel a little squirmy underneath. You being 205lbs need to go to 28c tires and pump it up to at least 90-100psi for the rear. "Plush" is nice,.. but not when you're getting pinch flats and squirmy feeling!
