  The charged particle transverse momentum ($p_T$) spectra measured by the
ATLAS and CMS collaborations in proton - proton collisions at sqrt(s) = 0.9 and
7 TeV have been studied using Tsallis thermodynamics. A thermodynamically
consistent form of the Tsallis distribution is used for fitting the transverse
momentum spectra at mid-rapidity. It is found that the fits based on the
proposed distribution provide an excellent description over 14 orders of
magnitude with $p_T$ values up to 200 GeV/c.
