Tkc + 908
Like many before, I have to say the stock tires suck offroad. I've been running TKC front and 908 rear for a couple of years now and really like that combo. I've ridden the TAT from TN to Salida UT with that setup and didn't have any issues with any part of the trail. Black Dragon wash was probably the most challenging section, but even that wasn't too bad. I've been getting about 4000 miles out of the 908 and 8000 on the TKC.
