I test fitted a whole bunch of wheels for upcoming winter. My Tesla is a daily driver for my wife and will be driven through a Chicago winter. I didn't want to try and find 21" winter tires for the OEM P85+ wheels...they are too expensive, and the wheels are temporary. Seeing that I'll probably will be selling them in the winter or early in Spring, it didn't seem worthwhile for me to order snow tires for them. I test fitted a few GM wheels, BMW wheels, and some others. I ended up with some BMW 20" wheels from a 6-series; let me know what you think (I know the tires are wrong size for the Tesla; they will be replaced with appropriate sized winter/all season tires. Also, I may end up using 10 to 15mm spacers for the rear and 10mm spacers for the front to push the wheels and tires out to make for better visual fitment. Let me know what you think, thanks.
