I just checked my spare for the first time and found that the dealership left it inflated to 20 PSI on its way out the door. I see some posts that make it look like Toyota eliminated the spare tire TPMS sensor beginning in 2009, and began to mark the spare for temporary use only for that reason. I have been doing 5 and 6 tire rotations for decades, and prefer to continue. On my '05 Tundra, the TPMS system would track 5 sensors. Will my 2010 Tacoma do the same if I buy a standard road wheel and sensor for the spare tire?
