Bolt pattern and OEM tire size are listed from the manufacturer's published spec sheet. Offset (ET) and hub bore are not always published by the manufacturer on consumer spec pages; values shown without a dash come from common platform fitment data and should be confirmed against the actual wheel before purchasing aftermarket wheels. Dashes (—) indicate values we could not verify from a public manufacturer source.
