The ALICE collaboration at LHC has recently measured the inclusive charged-particle jets production with different resolution parameters of 0.2, 0.3, 0.4, 0.5, 0.6 and 0.7 in pp collisions at 
= 13 TeV in the transverse momentum range of 
GeV/c and pseudorapidity range of 
. In this work, we have fitted the inclusive charged-particles jet production measured by the ALICE Collaboration by the Tsallis function with thermodynamical consistence to measure the freeze-out parameters: effective temperature (
), chemical potential (
) and non-extensive parameter (q). The quality of the Tsallis fits with fixed = 0 chemical potential has proved to be significantly better than those with fitted value. The fit parameters, q and measure the degree of deviation from the equilibrium state and the effective temperature of the thermalized system, respectively. We have established the dependence of the effective temperature, , and non-extensive parameter, q, on the value of the jet resolution parameter, R. We found out that the effective temperature, , of the Tsallis function shows a steady rise with increasing the jet resolution parameter. Also, a decrease in the non-extensive parameter q has been observed when the jet resolution parameter increases.
