I agreed. Whenever I check the spare, probably once every 2-3 years, the spare's pressure dropped 15-20 PSI. When I remember to inflate the spare while filling up at gas station, I always had the spare at max pressure on sidewall. The reason I do this is when I need the spare let say a year later, the pressure probably drop some and with pressure gauge in glove-box, I can quickly adjust it down to the level I need.
