All of my tires were inflated to 30 PSI as per the door label yet my TPMS warning light came on and a message "low tire". The dealer put 40 PSI in the spare and the light is out and no more messages. Cold weather causes tires to lose 1 PSI for every 10 degree drop in temperature.

The dealer should be over pressuring your spare as they tend to loose pressure from static/non-use. My 570 indicates each tires pressure and you can always spot the spare as it is much higher than the other 4 tires
