The TREAD Act outlines a number of specific TPMS performance requirements:

New vehicles must be equipped with sensors that monitor tire pressure in all four tires. Monitoring the spare is not required.
The TPMS system must operate when the vehicle ignition is on and warn when tires are underinflated by 25% or more.
The TPMS system must alert the driver when there is a system malfunction.
The TPMS warning light must stay on until the tire is inflated to the proper pressure or the system malfunction is corrected.
A "bulb check" of the warning light on the instrument panel must occur whenever the ignition is turned on.
Vehicle owner's manuals must contain warnings about potential incompatible replacement tires for the vehicle.
