I'm sure they won't be DOT legal but in theory they will work if the back spacing and bolt pattern is correct.
I was thinking of doing this at one time because they have cool color options and they are cheap.
Then I said F' it and got a set of DOT legal B.A.D. Wheels since I drive across state lines to go wheeling.
I would stay away from used dirt track wheels used on dirt track cars, but thats just my opinion after seeing them race/bumping. Not sure of how the guy with the cherokee treated them...? In general they are not as sturdy as "offroad truck" beadlocks from what I have seen, they are kind of made to be disposable in my opinion.
