You probably didn't need new tires unless you had some miles on it. Remember that the spare tire also has a pressure monitor as well. It most likely is causing the low tire pressure light on the dash and only needs to be inflated back to what ever your other tires are set to. I had the same problem on my RX and took it back to the dealership where they told me since the spare is exposed to the same elements (it's under the back of the RX - you have to use the tire iron to let the spare down), it will inevidably lose air.
Good luck.

I brought my RX350 to the dealer for this problem before. They told me to inflate my tires to 36psi for winter time although the recommended pressure is 30 psi

Contrary to popular belief the indicator light does not reset itself. Once you put in the proper tire pressure in all tires including the spare you must reset the indicator light. The reset button is located on the driver side underneath the dash panel. Stick your on the break pedal, turn and look up. You will see the reset button. With th engine on and park break on,push and hold te button for 5 seconds. The indicator light will turn off and you are all set.

there is a reset button for the tpms either just above the accerlator or to the right of the glove box. press it and tah dah....you should be good to go.
Testimonial: "Knowledgeable expert...found the button (but unfortunately did not fix problem--maybe shop messed up a sensor in the tire)"
