The inclusive hadronic decay-rates of the $\tau$ lepton are particularlyinteresting from the phenomenological point of view since they give access tothe CKM matrix elements $V_{ud}$ and $V_{us}$. In this talk, we discuss how arecent method for the extraction of smeared spectral densities from Euclideanlattice correlators can be used to obtain a direct lattice determination ofinclusive hadronic $\tau$ decay rates. We also present preliminary numericalresults obtained by applying this method to correlators measured on two gaugeensembles produced by the ETMC with $N_f=2+1+1$ dynamical flavours at physicalpion masses, lattice spacing $a\simeq 0.08$ fm and volumes $L\simeq 5.1$ fm and$L\simeq 7.6$ fm.
