Ambient temps in game?

Was wondering what the ambient temps are in game, taking some tire pressure fine tuning the the extreme. The rest of my car feels fine while in a drift for my playstyle, just want to have a very well tuned setup for my Formula D S13 (as in, built to competitive FD legal specs. You, know, powered by a 7.0L V8 with tons of power attached to NASCAR 4 speed gear setup and tires sized to its weight range)

I haven’t checked, does your tyre temperature at rest vary with profile, width, pressure, weather, time of day and the surface you are parked on?
If not, there’s your answer.
If so, all I can say is “daaaaaaaaamn”.

I don’t think ambient temp. changes from region to region, if that’s what you mean. Grip seems consistent accross the map.

I’m very curious now - do tires heat up and grip better like the FM games, since Horizon now has drafting too? I’m wondering.

I understand why you ask this. I’ve noticed sometimes when I’m drag tuning, most times I can catch the car on the clutch and get little to no wheelspin off the line and sometimes it feels like I can’t get off the line without drastic wheelspin. Maybe there’s more to the game mechanics than we thought.
