All, it just occured to me to ask: How many tire pressure sensors show up on the dash in the new LC? My LX570 shows all 5 tires, including the spare. Does the new LC do the same? I would think so but wanted to verify.
How many TPMS sensors?

Yes, the spare shows up, that’s how I knew mine was overfilled. It was almost 50 pounds.
Same for me... Mine was 53.
Yea, I figured so... however, the max pressure listed on the tire is 50 psi.
It’s a lot easier to let air out of the spare when it’s time to use it than the opposite…

Agreed... I had a similar experience recently (on a different car). Deflated my spare to slightly below 50 psi for that very reason 
Starting on page 559.

I wonder what PSI they had this set at from the factory. I also just had the same issue and ended up just resetting in the settings screen to the door recommended 33psi.
Question - is there a good reason to keep the spare inflated at a higher PSI? I can see it being a good idea if it didn’t have TMPS, but since it does, I’m going to know if it gets low.
