Some TPMS have high and low limits. This system seems to be just a low pressure sensing system. The TPMS will trip the light at 28psi (IIRC) and lower. Some have experimented with load range D and E tires and pressure towards 60psi. Nobody has reported a high pressure light.
Many have Revo's and other tires that are happy in the 40+/- range and they've reported no issues.
So... Just get the new tires and then :worthless
