Remember...under-inflated tire heats up FASTER than over-inflated tires. :nerd:

I check mine every 2-3 weeks (plus visual in between)... :wink:

Last I'd "properly" inflated at 35 PSI was when it was around +5 C

Now that it gets towards -12 C ... my resting pressure in the cold morning is at 34 PSI ... sometimes colder then I see 33 PSI (rarely, but will be more as it gets colder )

But here's the thing..as 1st mentioned...about heating time...:nerd:

As I rolled...within 3 minutes...I'm up 1 PSI.... and so as let's say a 20 min. trip...I'm perfectly inflated at 35 PSI !!! 30 min. @ 36 PSI ..etc. ( and this is in minus teens Celsius degrees )

I've always done this with ALL my vehicles... YMMV ! :nerd::nerd::wink:

If you use the increased tire air pressure associated with rolling/tire flexion to achieve the recommended PSI I would argue your tires are not inflated to the manufacturer's recommendation. The tire pressure monitor on my motorcycle will show the actual air pressure and a second number which ranges from 0 degrees to a "+" or "-" 1, 2, 3 etc...degrees telling me how far the tire pressure, when corrected for temperature, is off the set point.
I do agree with your practice of periodically inflating tires to 35 PSI when the ambient temperature has dramatically changed, up or down, but the logic of adding a few degrees to the set point during the winter escapes me. Again I'm assuming everyone parks their truck outside and inflates tires first thing in the AM.

I don't think mine is under-inflated...as you read... I inflated mine to the recommended pressure..and the ambient fluctuation is 1 or 2 PSI at -12C after the initial measurement at +5C

if one were to inflated theirs 1st thing in the morning at ambient temp of let's say +20C...which do you think is under ???

again...1 PSI under recommended pressure and takes 3 min at sub zero temp to achieved MFG recommended pressure is very close to "proper"..IMHO :wink:

take example another person inflated to 35 PSI at +20C vs mine as above ( last measured at +5C ) then the temp dropped to -12C...which is under inflated & which is not ??

I do believed however... engineers put it out there with tolerance in mind...so the proper way to properly measure is while cold ( how cold ?? just cold.. 1st thing in the morning fresh cold )..and we all should be fine as the range of difference is within tolerance ( not under & not over )
