I got my 295/70/17 Nittos mounted to day, and had them inflate to 35 PSI to start. Now my TPMS system is going nuts, saying I have low tire pressure, and rotating between 3 out of 4 wheels. I think it blinked 37 at me or something like that? Is that the threshold for it to warn me? I searched and didn't find anything like this. Ideas?

 

When I had tpms I had to overinflate to nearly 40, then come down slowly to 37 or so. It was finicky from the factory. I ended up dealing with the light so that I could run appropriately low pressure (30) then ditched the sensors and cleared the light with a flashpaq

 

Gotcha. Sounds like 37 is the magic number. Man, I'm gonna be riding like a skateboard at that PSI.

 

Getting a programmer or tuner to lower the threshold (or turn the system off when the sensors are removed) is a fairly popular thing to do.
