    Has anyone seen any data showing puncture resistance of a given tire at a certain tire inflation pressure? I am wondering (generally) if a tire is more or less puncture resistant at a certain pressure. I.E. Since lower inflation pressures allow a tire to be more compliant does this also mean that it would be inherantly more resistant to tread/sidewall punctures? Or would a higher pressure offer more overall punture resistance?

    I have not seen any data like that.

    My own personal experiences iare that the tread punctures by rocks have always happened when running highway, or near highway pressures.

    The side wall cuts have happened when aired down.

    Flats right at the junction of the tread and sidewall under both conditions (but mostly when aired-up)

    My theory is run lower pressure and watch the road/trail.

    Some people swearby running high pressure on a dirt road minimizes flats becuase the sidewall won't buldge as much and thereby be exposed to a rock or other object. My opinion is watch the road and have a smother ride while aired-down
