Nope. Google search winter rally tires.

Also running 35 psi on a 150 degree asphalt raises tire pressure from heat expanding the oxygen. When winter hits in Texas without touching the tires I lose about 10psi from the abient temp. The tire also does not get up to the same heat from friction of the road, that is to say the rolling resistance generates heat as well as getting heated from contacting the 150 degree pavement. That 35 psi in the morning can turn into 50psi really quickly on a long drive. However 35psi on a 35 degree pavement with a 35 ambient temp really won't affect the tire pressure so you would need to add more air pressure to get that same pressure youre running on long drives in the summer

Running nitrogen in the tires would cure both problems and tire pressure would remain constant through the temperature changes as it is not as heat sensitive as oxygen molecules

So yes I'm sure he's correct as I am forced to check pressure as Texas really only has summer and two months of winter every year lol
