    What is the range hit going to the Sport 19 inch wheels?

    I e-mailed Tesla and this is what they said:

    However, I think it'll be higher than that as I think they are using these wheels in their 220/310 estimations... so the car might get under 300 with the sport wheels... or at least it's possible. (298 miles going by the 4%)

    Hmmmm...

    The wheels and wheel wells are significant sources of drag. Some Model S owners have experimented with putting dish covers on the old standard 19" wheels and, as I recall, saw a 5%-8% increase in range (I don't recall what Tesla claimed the efficiency improvement was for the old 19" aero wheels). Ultimately, we'll just have to wait and see but I'm pretty sure those aero wheels are what's helping them hit their range targets.

    Remember that the 2-4" decrease on the Model S is from "normal" wheels not Aero wheels. So you have to add another 3-5% on top of the 2-4%. So my guess would be a 5-9% drop in range.

    It also depends on tire choices. the 18" Aero wheels come with Michelin tires, and the 19" Sport wheels come with Continental tires. (That could make a difference too.)

    What exactly does it mean when one emails "Tesla"?

    He must have Nikola Tesla's personal email address.

    You can email support and get standard boilerplate responses or conjecture that will change on who you talk to.

    So is that confirmed, Hankook for the 18" and Continental for the 19"? Michelin is out of the equation?

    I had done a pretty controlled test...see the link below where I drove my 19" for 38 miles while behind my wife in her 18". Net difference was about 7% difference, but could easily see 10% at higher speeds. I have since taken off her aero covers and seeing roughly 230 kWh/mile in her 18" vs 245 kWh/mile in my 19".

    True range of 19" sport wheels vs Aeros?
