What is the bolt pattern, 5,6, or 8 lug. I looked up the specs and was shocked to see this is a 12K lb RV with 15" wheels and D rated tires. I assume since they are a 15" D rated that they are a 6 lug. I've never seen an 8 lug 15" trailer wheel and most 5 lugs come on B or C rated. If they are 6, the only bolt pattern I am aware of is a 6 x 5.5". One thing you also need to check is the hub diameter. Although I am not aware of differences on the 6 lug wheels, I know other bolt patterns have different hub diameter openings.
