Expert Buying Guide for 2013 GMC Sierra 2500 HD Extended Cab
For your 2013 GMC Sierra 2500 HD Extended Cab, the 8x180 bolt pattern is shared with 2011-2013 models. The 124.9mm center bore requires hub-centric rings for aftermarket wheels to prevent vibration and ensure proper load distribution. Offset is sensitive; stock is 44mm, but aftermarket wheels should stay within ±10mm to avoid rubbing or suspension interference. Always use 14x1.5 lug nuts with the correct seat type (cone or ball) matching the wheel; mismatched seats can cause wheel loosening. Verify lug nut torque to 140 ft-lbs and re-torque after 50-100 miles.
