I’m just a fair weather cyclist, so I’m in need of education.
What benefits does inflating the tyres bring? I’d have intuitively thought that letting some air out and increasing the surface area of the rubber on tarmac would increase stability and grip, and the expense of efficiency.
I suspect OP doesn’t cycle every week, but is planning to very soon. That’s when this kind of maintenance check is particularly useful.
If you do cycle every week, you’ll notice pretty quickly if the tires are in need of some more pressure. In that case, there’s no need to plan ahead. You just go when you need to go. There’s no need to think about the tires every time.
I too need to clean and re-oil my chain.
I tried some grease last time and it seemed fine. Didn’t particularly feel any difference, except that it probably withstood the rain a little better.
If your tire does not break through to a solid surface, you will not get traction on snow regardless, unless you are using either absurdly large balloon tires, or a tracked vehicle. More pressure ensures that any knobs or studs or treads have the best chance possible of finding traction.
Interestingly, lower pressure and higher contact patch does not actually reduce efficiency on dry asphalt either. This is because elastic tire deformation is highly elastic, but the increase in rolling friction is small. In contrast, overly stiff tires convey more vibration into the frame, which is lost as heat, instead of being conserved elastically. Even on perfectly smooth indoor tracks, just they hysteresis losses from pedaling on an overly firm tire add up significantly.

Happy to learn though!

Its true, I haven’t cycled for a while but will need to soon. Flat tires will have worse grip on the road, as far as I can recall anyway…
When it comes to cycling in winter, I prefer to stick with the usual pressure. Using studded tires is also recommended, but not completely mandatory.
To be clear, my tyres were flat, even for summer weather.
Was about time for (un)scheduled maintenance then.
