Or in other news, the Patriots are cheaters because it got cold outside... at night... in January... in New England.
So how does the temperature affect tire pressure? There is a basic relationship between the change in temperature and pressure. When the temperature outside the tire changes, it will affect the pressure inside the tire.

For kickers and punters, this drag effect is compounded by the fact that cold footballs become under-inflated—in ESPN experiments (shown below), a football kept at 10°F for an hour had its air pressure reduced by 20 percent—which makes them less bouncy. As a result, they come off a kicker or punter's foot more slowly, and travel a shorter distance. The effect isn't enormous, but it's not negligible: In cold weather games, punts travel three fewer yards on average, and field goal accuracy drops by 1.7 percent.
