Were delivered with Arachnid wheel package. Wheels were mounted by Tesla Montreal, then then I realized within a few km that all four TPMS didn't work. Returned to Tesla and discovered they were the wrong TPMS. Since I drove on them for a few km, they wouldn't take them back. So I changed for the newer version of TMPS, and these are basically brand new and for sale. Located in Montreal, Canada. Would prefer to sell locally, but will ship to Canada and US for a proper offer. Could ship from US 12901 if you're patient, as I have business there in the next 7-10 days. Please send your offer. Tesla sells them for 350 CAD taxes included here. You know better than I what they're worth in the US.
