I cannot say for certain. If I am not mistaken, the bore centers on our wheels are ~ 4.773 inches in diameter, +/- a few thousands.
That is probably correct. Rickson's web site calls them 4.78". The 12k Dexter's are 4.75" so probably wont work.
Olde Bob, a trailer with 12k axles is a serious trailer so go ahead and spring for a spare, Lol
