Not sure, by why would you want to give up that safety feature running low-profile tires?
As far as I know, the Tire Pressure Warning ECU is not tied into the main ECM other the Combination Meter - Vehicle Speed Signal Tire Pressure Warning Light. You will get a constant light as in referenced information below. Note: The transmitters record actual PSI of each tire and that information can be displayed with the Toyota Intelligent Tester on CAN diagnostic port DLC3. Now if only these OBDII/CAN Informeters would display that data, that would be very beneficial in racing.
When the tire pressure warning light does not go off,
or when it comes on during driving, check tire
pressure. If the tire pressure warning light comes on
within several hours after adjusting the tire
pressure, the tire may have a slow air leak.
(b) Under the following conditions, the system may not
function properly.
• Facilities or devices that use similar radio
frequencies are located in the vicinity of the
vehicle.
• A radio device of similar frequency is used in the
vehicle.
• A large amount of snow or ice is stuck to the
vehicle, especially onto the wheels and around
the wheel houses.
• The battery of the sensor has been depleted.
• The tires without tire pressure warning valve and
transmitter are used.
• Tire chains are used.
• If any wheels other than the specified ones are
used, the system may not function properly
because interference may prevent the radio
waves from being correctly transmitted from the
tire pressure warning valve and transmitter.
• Depending on the tire type, the system may not
function properly even though the specified
wheels are used.
