I am trying to figure out the best way to take delivery of my Model X, but I have an odd logistical issue that I am trying to figure out the best way to handle. I am getting a p90DL but it has the standard wheels. I will be swapping them out for some beautiful black forged 21" wheels. I didn't want to go all the way to 22" due to our crappy roads and I was concerned about the 40lbs weight per wheel. So I found a 26lb, 21" perfect wheel and I'll be using pirelli scorpion Verde tires with have a really low rolling resistance and high tread wear. The logistical issue is with the the TPMS sensors in the X. Apparently whenever you change wheels, you need to pay the dealer $90 to reset the sensors as it can't be done by the owner. So every winter and summer wheel change, I'll have to drive to the dealer and pay them to reset them. (but only after I change the wheels myself, as they aren't allowed to put on non tesla wheels.) My dilemma is that when I take delivery, I'd like to have them put on the new wheels (which I will be installing new tesla tpms sensors in beforehand). I'd bring the wheels along and have them switch them out. But, they aren't allowed to put my wheels on. So my options are: 1. I bring a jack along and change the wheels myself in the dealer parking lot. The service manager said I could do this. Then they would reset the tpmrs. I'd bring the new wheels with the sensors already installed. Kinda crazy to stand in a parking lot and do this, but that is the only way around the tesla rule. or 2. I leave with the factory 20" wheels and have a shop that is allowed to touch the wheels take the tpms sensors out of the factory wheels and install them in the new wheels. I don't know if the sensors need to be "Reset" after this or not. If so, I'd have to drive back to the dealer and pay them $90 to reset, which I am trying to avoid that drive. Does anyone know if moving the sensors from one wheel to another requires a tpms reset? If the tpms doesn't require a reset, this makes the most sense. thanks. tony c. ps. I wonder when the car goes in for service if they notice the air pressure is low if they are allowed to put air in the tires on tesla wheels.
