This thread has been invaluable in helping me make a winter decision for my P3D+. Thank you all who contributed to this discussion. Considered all the options
1. Keep 20" wheels, buy all-season tires (keep or sell the Michelin Pilot 4S)
2. Keep 20" wheels, buy winter tires (reinstall and re-balance wheels in spring)
3. Buy new 20” wheels and winter tires, Store current wheels and tires and put back on in spring time.
4. Buy new 19” wheels and winter tires (uncertain if they will fit over the performance brakes). Store current wheels and tires and put back on in spring time.
5. And these were the options until I found that TSportline has an 18" wheel which will be better for winter roadways and I called to confirm that it has been modified to fit over the performance brakes.
So, decided to go with the TSportline 18" TST Flow Forged Tesla Wheel (Set of 4) in Space Gray for the Performance Model 3 with Performance upgrade for $1500 (free shipping) plus $45 for lug nut covers.
However, the winter tires they offer (Pirelli Winter Sottozero Serie 2) are not the best for ice and snow based on Tire Rack reviews. Instead opted for Michelin X-ice XI3 which are also quieter. So bought the wheels and tires separately and will store them until we install in November/December. Will store the 20" wheels and re-install in March. Hopefully, this way I will have the best of both worlds.
