I've had a question nagging me for a little bit, more just for my own personal knowledge than anything else since many posts wind up talking about range in one way or another. SR (Standard Range) Model 3 has a rating of 220 miles LR (Long range) Model 3 has a rating of 310 miles First thing I'm not clear on - Do the aero caps ADD 10% range, or is the rating of 220/310 measured with the covers already on? (If they were measured with the covers on then if you decide to take them off you'd get 198/279 for range with the 18" wheels without caps. If they were measured without the caps then you'd get 242/341 if you keep the covers on) Second thing - what effect do the 19" have on range compared to the 18". You would assume they're not as efficient as the 18" with the aero covers on, but they look like they could be more efficient than the 18" without the covers on. Last thing: - If there is a difference in mileage between the 18" and 19" rims - do we even know if this EPA range was tested with the 18" or 19" rims?
