I have a P85D and like all hate the tread life and cost of the Michelins. Many of you have talked about using the standard 245x35x21 on the front but going to a 285x30x21 on the rear. Tesla tech says that may cause all kinds of issues with all things that get sensed by the rear wheels but doesn't really seem to have any experience to speak from. I need new tires now, esp on the rear. The rpm on the stock 265x35x21 is 735 while the rpm on the 285x30x21 is 749, a 1.9% difference. I can totally live with that as far as odometer, mileage forecast, etc but wonder if anyone has done this and had any other issues like abs or traction control on curves or tire pressure misreading or anything else.
