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. I reposted this for locals in case anyone is interested in finding a winter set of wheels for their Tesla cars. The person I purchased these from has a slew of BMW wheels off of new dealership cars that have been upgraded with wheels. I told him that I'd help spread the word to Tesla owners that may be in the same situation as me. Let me know if you're interested in getting his contact info and/or seeing other pictures of other wheels I test fit on the car before selecting these. - - - Updated - - - Here's a set that I didn't buy: Offsets and width of these wheels are bit 'weaker' than I wanted, but still can be made to work with wider tires and 15mm or larger spacers.
