i just came accross a set of 5 KH steel wheels (the same style as on ANIMAL), except they are 15". Is there a reason to go with 16" over the 15"? I'm going to run the 34 x 9.5/15 swampers on them. Will the 11" brakes work on the 15"? The price is right on the wheels, trade for the wagon wheels that are on the '66 now!
