We present our best estimates of the uncertainties due to heavy particle threshold corrections on the unification scale [ital M][sub [ital U]], intermediate scale [ital M][sub [ital I]], and coupling constant [alpha][sub [ital U]] in the minimal nonsupersymmetric SO(10) models. Using recent data from the CERN [ital e][sup +][ital e][sup [minus]] collider LEP on sin[sup 2][theta][sub [ital W]] and [alpha][sub strong] to obtain the two-loop-level predictions for [ital M][sub [ital U]] and [alpha][sub [ital U]], we update the predictions for the proton lifetime in minimal nonsupersymmetric SO(10) models.
