I ran the pressure only a half pound over what it takes to keep the low tire warning from coming on. And they still wore in the middle.
I would fill them to a lower pressure and then reset the TPM to calibrate it around that pressure. The sensor goes off when the pressure drops about ~ 8-10 psi below the pressure that you set the sensor to. It is a relative pressure measurement system.
