I am not sure what you are talking about.  Pressure is not given in lbs.
Are you talking about the weight of the tire itself (maybe about 35 lbs I
suppose)?  If so, that will be
taken into account with the measurement and calculation I proposed.  If
you are talking about the pressure in the tire, 35 lbs/square inch is
approximately correct, but I certainly did not overlook that fact, that is
the whole point of the measurement.  Obviously the method I suggest makes
certain assumptions, the most obvious being the ability of the tire itself
to support weight through sidewall stiffness rather than air pressure but
it is not at all apparent that you are talking about this effect.

I suggest that if you intend to cast dispersion upon me with what appears
to be sarcastic reference to the institution I attend that you at least
make an attempt to get your units right.  By the way, for what it is worth,
I spent many of my formative years on a farm - did you?
