some people buy a wheelbarrow wheel from home depot pump it to whatever PSI, throw the 4 sensors in to fool the system
someone on the GS forum went as far to drill new holes in the wheel in a location which would make the TPMS compatible, so you have two valve stems, pretty hidden tho

i was hoping to get some black steelies to put some winter tires on except lexus says the tpm wont fit on them
they also said its possible to just put them all in the spare tire space..or something along those lines

The "tire pressure monitoring system" will trigger an error lamp on the instrument cluster, if it detects low pressure or a missing sensor..
Your tire pressure is indicated on a label attached to the inside drivers door jam. This is the pressure for any wheel.
The wheelbarrow trick should work better with a tubeless tire and wheel. Install the four sensors inside the small tire and pump it to the recommended pressure. This should satisfy the pressure sensors and reset to lamp off. The tire is placed in the trunk, within radio range of it's ECM controller.

The Lexus system may be different, but I thought that the TPMS's measure tire pressures by monitoring the rotational speed of each wheel, comparing it to a known "good" value. If the tire looses air, the rotational speed increases (smaller circumference), and triggers the warning light. Again, the Lexus system could very well be different.

Also people ahve done the wheelbarrow thing and it works so its measuring straight pressure

If you reuse the sensors that came with the car and put them in a pressurized wheel, the car will not throw a code (but you do not have the function either).
If you buy new sensors, make sure you write the serial numbers down prior to sticking them in any wheels. Then you have to go to the dealer to have them initiated to the car.
