trips

Hello all, I had posted a different thread several weeks ago, but since we are in a new year, I thought I would start out with a new one. I have a 2015 3.8 AWD Ultimate (black on black), which I like very much. I got a great deal, added the 100k warrantee since it had a couple thousand miles...

I have higher profile tires with wider treads and therefor the load capability is greater for any given pressure. I would like to run 28 max but theTPMS seems to trip at 29.5 - 30 psi. I would like to lower it to trip at 27Psi.

:(I'm embarrassed to admit that I probably am not smart enough to figure out how to use the trip meter to track two trips at the same time. It seems like whenever I reset one trip, it resets all or part of all trips. I love the display, its well laid out, but I just can't figure out how to do...
