As I understand it, you will get a warning when it drops below 3psi from where you have it set. Temp change = correct pressure, reset tpms. Get a digital gauge to check it on the reg during seasonal changes. Aftermarket wheels disregard factory recommendation as they are for factory stated set up. I run 20s at 39 psi front and rear that have a max of 50. Got mine coded to show pressure and temp but same as ezair's no info. TPMS may not be able to monitor that info on the 2011s or 12ss??? 1st world problems.
