Lol, only one tyre ("Truck Scrubbed" if memory serves), however given that they will go sideways at the drop of a hat even on a nice warm, dry track I'd say a slippery surface is not required. 1300+ hp will do that I guessThis really needs to come to console, I would run these trucks online so much.
Do they have snow tyres?
AMS2 gets my vote as one of the most immersive titles around.
