While looking at the motor trend Model 3 review: Exclusive: Tesla Model 3 First Drive Review - Motor Trend The Motor Trend review has a close up of the tire: http://st.motortrend.com/uploads/sites/5/2017/07/Tesla-Model-3-wheels.jpg If you take a good look, you can see the size, 285/40R19, and its a conti procontact A quick look shows this: Continental ContiProContact They are 335(!) a tire. Curious if we've seen the 18'' tire sizes anywhere? A look at other tires in that size, seems to be between 250-400 per tire. A brief reminder: Since you won't be bringing in your car for regular maintenance like oil changes, with RWD cars, you REALLY should rotate your tires regularly or you'll end up burning out the RW tires quick, especially with the instant torque.
