https://www.ebay.com/itm/2016-16-BM...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649 I purchased a spare rear wheel. I paid significantly less than the listed $800 for it. Seller accepted my offer. The wheel showed up yesterday. Complete with TPMS and a rear tire with a few thousand miles left on it. I can use my GS-911 tool to register another TPMS. MSRP on a new wheel is $1235, $186 for new TPMS sensor, tire with miles left is a bonus. With two RS's in our garage, I'm sure it will come in handy at some point.
