Yep. MT, Mud Terrain.
And it all depends what class you are racing as to what tire you run. yea, the big boys are running the Baja T/A KR3's. But a lot of the other classes without the high power high speed rigs, run the KO2's.
And some classes run the Baja A/T at KoH.
While the look is still the same as the 90's for the most part, the tech is a lot different. And the KO2's have side tread that the old '90's didn't. No need to change the classic A/T tread pattern when it works.
