I picked our M3P up back in June, here in Florida, so we've had mostly warm weather up until a few weeks ago. Got a low tire warning (from just one), just 1-2 lbs under what I assume is the warning trigger (looks like around 35 lbs or so?).
I aired them up cold to 40 PSI (in the garage, where it's usually low 60s), and that puts me at 44 PSI on the highway, with a light-to-moderate weight load (a few rollers, me and the two girls).
So over the last couple of months, I've made the trip from home to the Orlando airport (MCO) several times: same directions, I tend to keep it about 5 over so roughly the same speed. Before I aired up, I had been parking (always the same place near the Hyatt) at 45-46% remaining. With the higher (i.e., proper) tire pressure I arrived the last two times at 53%. So definitely a notable difference, and these last two trips I also ran the heater for a bit (maybe 15-20 minutes here and there), so the actual gains are very likely even better (given the hit from the heater).
So I guess check those tire pressures with the cold weather, get a good gauge, enjoy the extra XX miles of range
Side note: the Deltona/Wawa SuC is really terrific, lots of food/drink options, close to 95/easily accessible, plenty of space, kind of isolated so a nice place to chill for 10-15 minutes (and I've seen it a bunch over the last two months ...) The Daytona Beach SuC has more chargers, but it's a good mile off of 95 and in a Target parking lot that's a bit of a clusterf*** ...
