Here I go:

front is a 17mm rim, 25mm tire. Rear is a 20mm rim, 25mm tire. I weigh 135lbs.

I run 40-60 psi in the front and 50-65 psi in the rear.

I use tubes. I have never pinch flatted. My secret? Sealant... in my TUBES Iíve felt my rim clobber square edges HARD but Iíve never lost enough pressure to notice.
