Tire Pressure ?

Tps light stays on, put 35 psi all the around, still on, a friend told me he puts 50 psi cold, damn, speaking of Fred Flintstone ride, What is your input ?, Have 265-70-16 street tires, on 08 Prerunner 4 door Thanks in advance , Milo

 

I'm guessing bad sensor. Have you reset the system?

 

Check the spare?

 

My vote as well.

 

Depends on the model year but, yea that too.

ON EDIT: Found he has a 2008 so def could be.

 

had a 2008, same thing happen to me and it turned out to be the spare

 

Yep... in the winter the spare stays cold when the others heat up... when there's around a 8 psi difference it will trigger the light. In the winter take the spare up a few pounds above the other 4 to compensate for this. Don't forget to reset the system.
