If they say they are accurate to plus or minus 3 PSI then they need to be accurate to plus or minus 3 PSI and at 105 PSI that gives them 101.85 (102) to 108.15 (108). I should not be seeing readings of 109, 110, 111, and 112. I'll surrender 109 for rounding.



I am more inclined to give an RV manufacturer the benefit of the doubt on loose screws or misaligned cabinet doors than I am a TPMS or other safety device manufacturer being off by over 2 percent outside of their published tolerance. As I asked them, if I can't trust the readings when the tires are cold and the vehicle is stationary, how can I trust the system to alert me when the tires are hot and I'm rolling down the road at 65 MPH.



It may be acceptable for you or others but when it comes to the lives of my family members it is nowhere near acceptable to me.

Best of luck.
