I just orders a 5th rim, and a friend pointed out that I will be wanting a TPMS sensor if I intend to rotate this tire with the others.
The part is 42607-02050. The wheel (just for the record) is PTR20-35110-BK. I ordered the wheel from Serratoyota.com for $209, free shipping!
The above dealer sells it for $72.90 and confirms that this will fit my 2023 4runner ORP.The next outfit shows the same part number and a price of $19.98 for a part made in Germany.
The stems on my existing wheels are hard black rubber.Tom's Auto repair pages / tom@mmto.org
