I just put on my TMPS and they say 76 psi, the tire gauge said 80psi which one is more accurate? I know TST say theirs are + - 1.5 psi, so which one do I believe? Thanks as always
If you REALLY need to know which (if either) is exactly right, call around your local tire shops and see which one has a certified master gauge. Check your TPMS and handheld gauge readings against that.
