On Amazon;
The Cheng Shin knobby is about $111 for 2 shipped.
The Wanda knobby is about $118 for 2 shipped.
The Duro knobby is about $125 for 2 shipped.
The Carlisle knobby is about $147 for 2 shipped.
The Cheng Shins seem to be decent, they are tall and narrow. I saw in another thread where someone mentioned the Duro Knobby was fatter with less sidewall flex than than the Cheng Shins. Not as smooth a ride. Carlisles are fatter like the Duro.
Maybe not a big difference in all these 2 ply knobbies. Not big enough to spend much time pondering anyway. Just had not seen much on the Wanda knobby tires.
