I also expected we get studded winter tires but it looks like they are without studs.
This is also a problem in RBR, this game was never designed to use wrong tires for other surfaces, like snow tires on tarmac etc.
With NGP this has changed a lot, snow tires working way better on Tarmac now. Also slicks are working quite well on snow since the last update.
But also in RBR there is no "montespike" model, so just the small "swedenspike".
I agree with you, monte is a lot of fun in DR 2.0.
The difference in the grip on snow and ice is very nice and i really like how it feels, just a ton of fun drifting from corner to corner on the ice/snow! 🙂
