OK so I got some adapters that are 2in spacers and I wanna us them there the 6x4.50 lug to 5x5.50 lug and I just finished lifting my Dakota up using lift keys add a leafs and a body lift (its a 93 Dakota with the 3.9l) will the spacers affect the size of tire I'm able to fit on there with out rubbing??

 

Yes it will let you run a wider tire without rubbing on the frame, but you may run into issues with the fender well lip since you will be sticking out further. Best thing to do is try it.
