Sorry my friend but you are very wrong!
It is neither air nor road temperature that is most important! TYRE temperature is what's most important, as the whole point of Winter tyres is the rubber stays softer at lower temperatures!
And second most important i would say is air temperature, as the more of the tyre is in contact with air than road, so air will affect the tyre temp more!
