    According to the following chart you'd need about 90psi front, 110 psi back, to avoid pinch flats -

    Are you getting the punctures on the back? Is there 2 holes in the tube for each puncture?

    Very handy chart that alright. I run 100psi all the time, dont have any issues, but then again I am very light.
