Accurate reconstruction of charged particle trajectories and measurement of their parameters (tracking) is one of the major challenges of the CMS experiment. A precise and efficient tracking is one of the critical components of the CMS physics program as it impacts the ability to reconstruct the physics objects needed to understand proton-proton collisions at the LHC. In this contribution, we present the tracking performance measured in data where the tag-and-probe technique was applied to $Z\longrightarrow \mu^{+}\mu^{-}$ di-muon resonances for all reconstructed muon trajectories and the subset of trajectories in which the CMS Tracker is used to seed the measurement. The performance is assessed using early LHC Run 3 data at $\sqrt{s} = 13.6$ TeV.
