For those of you worried about getting tires installed and someone who knows how to work on a model 3....give Spence a call at Spence TIres. He swapped my aero rims and winter rims with tires while doing the caliper paint for me yesterday. He's worked on over 100 model 3s, and was a great guy. Not sure if he really is in the business of doing tire swaps per se, but I would recommend him if he is willing to do the work. Here's the thread with his contact info/painting work he does.
Red Brake Calipers - incredible work and price!
