Tire Rack! Online. Set of four top-of-the line for around $1000. We're NOT talking racing slicks or other silliness, just good tires for daily driving that will last 40,000 miles or more. Tires I order are usually here the next day, and I throw them in the back of the car for taking to my favorite tire store for installation, at a cost of an additional $100 or so. As always, YMMV. Any ordinary tire shop can put tires on correctly, as their business depends on it, and yes, they know how to jack up Teslas. They've been doing mine since 2012.
