It turns out that Tesla has most likely changed the bolt pattern for the M3. The MS 19 inch wheels use a 5 x 120 bolt pattern. We now have an indication that the M3 will use a 5 x 114.3 bolt pattern. TSportline has a M3 wheel guide: The Tesla Model 3 Wheel and Tire Guide Bolt Pattern TSportline and Tesla sell MS wheels with a 5 x 120. This makes sense to me. As the M3 is much lighter than the MS the disc brakes and corresponding hubs don't need to be as large. Using a smaller bolt pattern may keep the design in scale. Both 5 x 120 and 5 x 114.3 are very common in the industry. I'm contacting TSportline to verify.
