I am not sure about what I am going to say, so...... I think when you rotate the tires on the newer Tundra's that display the tire pressure for each wheel on the dash, you have to reset the TPS system so it can re-learn which tire is at which location. If you don't do that, it will think the rear tires are displayed as the fronts, and the fronts are displayed as the rears. Is it possible that when it says the front tire pressure is low it is actually reading the rear tire pressure and just displaying it as the front? You might want to put a real gauge on each tire and see if the reading matches the display on your dash.

The other thing to check is if you have a dead battery in one of the TPS sensors. My '15 CM needed a new battery in one of the TPS sensors this summer for the first time. The symptom was a low tire alarm light always on. I think it blinks like 2-3 times and then stays on which indicates that the computer could not communicate with one of the TPMS sensors. The other symptom was that all the actual tire pressures checked good, so I knew there was a communication problem. They had to replace one of the TPMS sensors for about $140 (I went to a local tire dealer who used a non-OEM TPMS sensor).

One last thing. The Tundra's have a reset button that is located below and to the right of the steering column. You might try airing up all the tires to spec and then pushing that button to reset the system (see your owners manual for the exact procedure to reset this). If someone reset it at a higher pressure, the system will alarm when the tire pressure is somewhat below that value (I think it alarms around 3-5 psi below the pressure it was reset at last). If for example someone reset it with the tire pressure at 37 psi, and you are running at 32 psi per the sticker on the door, you could be right on the verge of alarming all the time.

Good luck.
