Just happened to see that Interco now makes their revised TSL/SX II in 33x9.5, 35x10, and 37x12 sizes for 15, 16, and 17" wheels: http://www.intercotire.com/tire/148
Not sure how long those sizes have been out, to be honest, but last I checked I hadn't noticed them.
There's even a set of 4 of the 35x10/16's in their blem inventory for pretty reasonable: http://www.intercotire.com/blem_list_0
(<- handy link to check every once in a while, FYI)
I wouldn't suggest them for street use beyond driving to and from the trail, but they are a proven leader in super tough, high-performance off pavement tires, especially on the east coast and the PNW areas that see a lot of mixed terrain. I'd also consider the 35x10 about as big and heavy as you'd want to put your IFS through, as you'll be putting a significant strain on your steering system, not to mention your poor CV's
