@8up-local If it is what I think it is (slices to a block of rubber, without cutting out any material) it is roughly doing same thing as softer coumpound does.
By a slice, one big block is effectively turned into two independent blocks, that can slide against each other (heat up via friction) and thus follow better actual shape of hard surface, provide better traction as a result.
Speaking of game, I am not friend of wild spinning on tarmac in MR way, on the other hand, in the sake of game mechanics, off-road tires should have noticably less traction than road tires (on hard road).
LESS, not NONE!
I dunno, this is to a much smaller degree but the concept is the same. I've driven plenty of ATV's, and have taken lots of paved roads. And honestly I can't say ATV's lost any traction on pavement, if anything they gained traction.
Generally offroad (and snow) tires are made out of a softer compound to help grip better in slick conditions. This is why it's highly recommended to NOT use All Season tires in winter. Because while a All Season tire may have slightly more aggressive thread then a straight up Summer tire, All Seasons tires (so they can last in warmer weather) are still made from a harder compound, and lose grip in the snow.
Usually there are 2 downsides to using a Mud/Snow tire on a hard surface like roads. First because they are a softer tire, they will wear out much faster. They are made for mud or snow, they are not a highway tire.
Secondly mud/snow tires are usually bigger and wider, which effects your ability to corner and steer in a negative way. A vehicle with big wide offroad mud/snow tires will have a decreased turning circle compared to a vehicle with smaller tires. Going back to the ATV example, this very reason is why ATV's have skinny tires in the front and only put big wide tires on the back.
But as far as a actual lose of traction going from dirt/mud/snow onto pavement. I can't say I've ever experienced that. Not unless there was ice, but we aren't talking about ice here.
