Change your tires. I saw zero difference in range switching from Aero's with covers and primacy tires to 19" OEM wheels with Pirelli P7+ "Eco" tires. Those Continental tires are what sucks. I bought rims from Tesla and tires from Tirerack because I knew those 19" OEM tires were crap (not just for efficiency either). I'm now stuck with similar Continental's on my Model X and can't wait to get rid of them, before they blow out a belt or something.
