With 26 x9x14 tires you will likely get minimal clearance between tire's shoulder and the portion of the swing arm where it necks down towards the front. Others have addressed this via an extended swingarm, a 8 inch tire width, a 12 inch trailer tire and/or tread trimming.
Fortunately the Kendal and AMS both seen to have nice rounded profiles so may avoid this issu.
Also the tread blocks look substantial enough to hopefully avoid the squirrelly handling that some tall delicate flexible treads deliver. For example the Ripsaw and Buzzsaw tires experimented by others here were disappointing.
