>> In very cold weather pressures would drop quite a bit.

Fairly straightforward to work out, assuming as an approximation that the volume of air in the tyre remains constant.

Pressure is proportional to temperature, not forgetting to add 273 to the temp in celsius and 1 bar to the tyre pressure readings, which are only measured relative to atmospheric.

Tyres set to 33psi at 25C would be at c. 29psi when the temperature is 0C.
