need help with 15x12 wheels

I bought a set of billet specialties RT 15x12 with 7.5bs. I went to test fit and the rear drum hits the inside before I can even get it all the way on. Ideas plz????

What's your backspacing?. From what I've read. 12" is the widest we can go without rubbing. What year is the truck?

Re: need help with 15x12 wheels

How far off is the wheel from seating fully around the wheel studs? Some pics might help.
