Little confused. Procal description talks about modifing the tpms to work when ur wheelin. My question is can the procal turn off the tpms or does it only allow you to lower the psi until the light goes off? What I'm lookin for I if I need to get tpm vavle stems for my new wheels. If the procal let's me not get new ones I'm jus gonna get the procal since I gotta change the tire size too

 

All the ProCal does in regards to TPMS is lower the threshold pressure at which the light comes on.

 

You could transfer your sensors from old wheels to new and use the procal to set low pressure to 10psi or so, or don't transfer sensors and use procal to set low pressure to 0.

I've personally set my low pressure to 25lbs and run my 35s at 30lbs, and don't worry about the light (and occasional dash ding) when I air down to 15lbs. It resets after I air back up and drive a few miles.

 

Ok. I think I'm not gonna use or tansfer the stems and ill buy a procal. Makes more sense. Especialy to reprogram for the bigger tires. .. thanks for the input

 

The ProCal let's you set the new pressure to whatever you want. Set it to '0', and the system is disabled. No light, no dings, nothing.

Those tpms stems are easy to break, and it gets very expensive to keep replacing them. With a ProCal, there is no need to keep them. But if you decide to swap them to the new rims, consider having them banded inside and run rubber stems.

 

With what u jus said above im jus gonna spend the 150 and get the pocal. So much less risk. Plus I plan on swapping back to the stockers durin the winter. I dd perfectly fine with my stockers with the 3rd biggest blizzard chicago has ever seen. Rather not get salt on my nice wheels.

 

I set mine to 0.
