TPM went on the other day and when I checked the pressure it was 30 PSI all around. My gauge is very accurate. As soon as I filled it to the 32/33 PSI the light was off. And its funny because I had noticed a slight difference in the handling for a week or so also. Didn't notice the PSM light during that week because at my height the light is obstructed by the steering wheel so I never thought the inflation was off. I assumed the handling situation was due to the high winds NY was experiencing at the time. Filled the tires to the recommended pressure and it seems fine again.
