TPMS warning goes off today, no big deal, temps dropped 20-25 degrees which caused the tires to sink from 30PSI to 25. I aired them up and still had warning, I went 5 lbs over and then 10 lbs! Son of a gun, what to do? I call the dealer and say, any ideas, the car has like 1600 miles on it, it's just a pup? They said, yup, spare tire probably sunk down in the cold weather. Sure enough it was at 25lbs. PIA to drop the spare just to air it up. Anyhoo, just sharing in-case someone like me did not think to check the spare.
Yup this got me a few months after I got my Highlander. Filled up all tires to around 37 psi and still had the warning until I remembered I had a full-sized spare. Low and behold...it was only around 26 psi. It only cost me another 75 cents in the air pump.

I learned the hard way that the SPARE was actually detected by the TPMS system. I filled the tires with air, dropped them down, his the reset and unhooked the battery. Then posted here abd someone indeed said the SPARE is also detected in that mix. What a PITA!! Was at the station, dropped the tire and filled it up...
I guess it is nice to know iof your spare is flat before you really need it
I usually drop my spare once or twice during the winter to clean all the mud off of it and the undercarriage, and take that opportunity to fully inflate the spare.

It now looks like the Sears Compressor I bought a couple years ago was a smart thing to have in my garage. Sure was easier to do it at home than the gas station.
Like I mentioned before, you can try flipping the tire over. Done that on the Tacoma. I wonder too if the 2011 HL still has the TPMS sensor in the spare? My 05 Tacoma doesn't have TPMS, but they began putting it in all 5 tires a year or two later. Then in '09, they suddenly dropped it from the spare. Now it's only in the 4 main tires. Interesting if they still have it in the spare on the 2011 HL since they're dropping it from other models (even without a refresh).

replace air with the Nitrogen in your tires. It's not get afected by the temp that much. We get temp fluctuations from 60F down to 20F and back in one week in the winter.
If anyone tries this please post your results, much easier than having to drop the spare to access the valve stem.
I just tried it out (since it was my idea). And I decided against it for one reason alone: the bracket that holds the tire up might scratch the center hub on the good side of the wheel when reversed. That didn't even occur to me because the spares on the Tacoma are steel wheels so it wasn't an issue. You could add a piece of rubber to protect it, but I didn't know if that would still cause marks. I'm sort of a perfectionist (or obsessive compulsive) with stuff like this, so I'm not willing to risk it. People see my 6-year old Tacoma and think I have a brand new vehicle because of how well my wife and I take care of our things (as long as you don't look closely at all the scratches from off-roading...but that is why I got white after all!).
Compared to the Tacoma, it's a snap to drop the spare on the HL. But if you're willing to spend around $25, there is another option. One person did this on their Tacoma: http://www.campingworld.com/shopping...inflators/6080

I've heard it listed as a percentage, but the service manager at the dealership told me 2-3 psi. I've heard others say anywhere from 2-4 psi. So somewhere close to that.

Normal PSI is 30 on the placard. All of mine fell 5lbs to 25. I am not saying it would have not come on at 28 or 27, just when the cold weather hit, mine all fell to that level overnight and the TPMS triggered the next day.
I installed winters with TPMS sensors I bought of ebay, after reprogramming the light is off, but I drive to work close and haven't had any long trip so I am not sure if they work or not. How long should I drive to make sure they are fine?
