Cadillac Escalade Rims

Purchased some cadillac escalade rims for my Mighty Max after seeing them on another Mighty Max on the net. Checked bolt pattern and all was good, I thought. Went today to get em' put on but was told they would not fit because the tabs on the rotor. Has anyone else had this problem? If so what was the fix.

THanks!
