Q: Why pick 20-inch over a smaller wheel on the Model 3?

Twenty-inch sizing sharpens initial turn-in and lateral support versus smaller diameters while keeping enough sidewall to stay composed on real roads. Paired with forged construction, the assemblies cut rotating mass compared with heavier cast wheels. Less rotating mass helps damper control, which shows up as cleaner mid-corner tracking and steadier braking. It is the sweet spot for owners who want a performance feel that still commutes.
