You are usually supposed to set your tire pressure when cold (and adjust it seasonally) so that shouldn't be an issue.

- falcolas 4y agoNope. Don’t fill them up to spec while cold, otherwise when driving they will be overinflated - possibly dangerously so. As you run on cold tires, they heat back up, and the tire pressure comes up accordingly. At moderately cold temperatures (20 or so), that can be about 10-15%. At -20 or so, it’s almost 25-30%. Potential blowout territory depending on your tires condition and age. In more extreme cases, the tires may look dead flat while cold, and perfectly normal once warmed back up. The volume of air in the tires hasn’t changed, just it’s temperature. And they’re easy to get back up to temp with some easy driving for a few miles.
