BMF Wheels just released new fitments for 2011 GM 2500HD trucks with the new 8x180mm lug pattern.
With the 2011 chassis and powertrain updates, GM created a new spindle/hub for their trucks and in doing so, the lug pattern change.
Wheel companies have been slow to respond to the update, but BMF now has S.O.T.A. and Novakane wheels ready to ship just for the 2011 GM 2500HD trucks.
