I posted over on TMC. Copied her for us Canadians. 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. Just spoke to TSportline and they said the information they have from Tesla is the M3 bolt pattern is indeed 5 x 114.3. They will be confirming this later this month an a customer car. If true this locks out using ANY MS wheels on M3.
