Those are mighty expensive for something you probably won't be happy with.
Our trucks' suspensions are tuned for radials, and they make bias-plies ride like crap. That was something my Dad rediscovered when he "got a good deal" on some 7.00x15 Power King highway bias tires for his '81 C10 some years ago. Didn't take long before he went back to radials, price be damned.
That said, Tire Rack has 235/85R16s (about the same size as a 9.00x16, as I recall) in every type, most of which cost less than those Cokers. It's your money, but I'd stay with radials if it were my truck.
