The launch data is U.S.-focused and manually curated. It is not a complete tire availability, vehicle fitment, live recall or inventory API. The checked date is attached to the data. “Current manual” Tesla entries must not be silently reinterpreted as a historical model year.
Preserve source URLs, dates, axle distinctions and application notes when using these records. Nominal sizes do not establish compatibility. Manufacturer terms and the exact vehicle label must be verified before purchase.
