Sometimes during transportation, they'll overinflate to prevent any flat spotting from occuring. This can also occur when vehicles sit on the lot for an extended period of time (pre-covid)I just picked up my BS BL last night and just noticed the tire pressure on my Falkens are at 41-43. I guess I need to let out some air if 33 is recommended.
I'm going to take a shot here. We don't recommend filling tires when they are "hot" after a drive as air is not stable. Your cold pressure is whenever the vehicle hasn't been driven for more than 4 hours. To put simply, the air temp inside the tire is equal to ambient temperature.BS BL+BL+Falkens here, and I've stuck with ~36 psi cold ... however stock fill for me was nitrogen, so there's little expansion to operating-hot temperatures, which are only ~37 psi or so after multiple highway hours. I'm only at a bit over 2,000 miles on the tyres, wear pattern to date looks even.
Don't have access to localized tread-block temperature instrumentation, which is what one uses on the track to determine uneven loading (inferring a pressure to load mismatch).
FWIW, the ForScan data (via OBD-II) does also let you see per-TPMS module temperature readings, which might be of interest when towing or aggressively offroading.
@Falken QA -- Do y'all have target operating-hot temperature pressures tracked also? This makes a big difference for folks using room-air versus a highly dried (nitrogen / CO2) fill.
As for a "sweet spot" air pressure recommendation, the sweet spot is making sure the air pressure used is supporting the load of the vehicle & it's contents.
