I've been off and on in the market for a staggered set of Grey Turbines, and finally was able to snatch some off a forum member, @MTBHXC. This gentleman was great the whole way through in facilitating my staggered set with tires and shipping them nicely wrapped. Again, shout out to @MTBHXC. Great member to do business with. Service Center Visit Next I needed these babies scanned to see which TPMS they had, if they still had good voltage, tires remounted and balanced if new ones were needed, then new center caps, lug nuts and lug nut covers; and finally, mounting of the 21"s onto the car. My SC was able to perform all of this, consolidating it all into a 1-stop pleasant experience. First off, they started by scanning the wheels/ tires to verify which sensors they had. Unfortunately for me, they all were the older type (baodong or whatever). So off they went to have tires dismounted, new Continental TPMS installed, then remounted, balanced, installed on the car with a revised type of lug nut that accepts the black lug nut covers, and my 19" Slipstreams sacked away in Tesla tire totes--all while I BS'd with OAs in the showroom and drank their Keurig for around an hour or so. Total out-the-door damage came in at $453.90. Itemized, it was: 4 TPMS - $200 20 Lug nuts - $17.60 4 Center Caps (looks like I was only charged for 1) -$5, should've been $20 20 Lug nut caps - $8.00 (.40c each from Tesla, people. Don't be duped into buying ones from a vendor here for a laughable $50 or even cheaper amazon caps at around $12 when you can have the OEMs for $8.) 2 sets of Tesla tire totes (4 total) - $80 Labor - $120 Taxes - $23.30 It also appears they replaced the LH and RH parking brake calipers per that recall while performing the wheel change. This may have been what added the most time to my wait. No problems there. The main purpose here was to express the good buying experience from a forum member, and the equally fine job Tesla did at making it all a 1-stop walk in the park. I'd like to add that the tire totes are of great quality! They cover the wheel and tire well so you can stack them on top of each other without worry of scratching or gouging adjacent wheels, have carry handles and nice Tesla branding on them. On that note, I didn't feel like the Turbines with tires were that much heavier than the Slipstreams with tires, as I lifted them both up today at different times. I was really expecting the Slips to be much lighter. This is all going by the bicep meter, so take that as you will. Hope this helps others that may be considering the same thing, and I'm happy to go into detail regarding any of it, including specifics on the invoice.
