New M/T tire on Tundra, air pressure light always on

Hello All,

I installed new M/T tire on my Tundra, and now the tire air pressure light is always on. Previouslable I had H/T tire.

Any suggestions?

Check the pressures.... including the pressure in the spare.... they all need to be within 5PSI of each other or the light will stay on. If the tire guy busted one of the sensors while dis/mounting the new tires, then all bets are off.

how do the sensors know whatthe air pressure should.

the new tires have new air pressure requirements...

The sensors look for a pressure diferential and send their information to the vehicle computer.

Exactly..... make sure that *ALL* the tires are within 5 PSI of each other. Like I said before.....unless the tire guy screwed up a sensor, the likely suspect is probably the spare. Depending on the tires you put on your Tundra, the likely pressures of the new tires is probably either going to be around 35psi for passenger car tires, or 80psi for commercial or heavy duty tires. The stock Bridgestone Duelers that the Tundra comes with take 44psi.

Just a thought.... you did stay with the stock wheels, didn't you??

The sensors are in the wheels.

All 4 tires need to be the same diameter !!! I'm not sure The tire pressure sensor measures the difference in axel speed not the actual air pressure

It measures actual pressure differential between the 4 on the ground *AND* the spare. The idiot light on the dash comes on if the spare is low.
