14" wheels & tires
won't fit unless you raise the trailer high enough to move the axles farther apart.
13" wheels and tires j-u-s-t
fit; an owner in Oregon switched to them years ago... but that brings the tires
within 1-1/2 inches of each other at their center-line... leaving no room for any commercially made chocking system that goes between the tires, and brings the tire very close to the edge of the wheel well.
