out of all the site i look at that discussed the Model 3 wheels, what hasn't been discussed is the fuel economy of the different sizes. My question is what would the different in fuel economy between the 18 vs 19 inch wheels? We know for the S and X they shows the range difference you would see between its 2 wheel sizes. But what hasn't been mentioned is the difference between the 18 and the 19 in. Does the 18in give better range but less grip and rougher ride compare to the 19 in? by what degree? is it just all about looks?
