From the Owner:

Check out our customer Rheal from Desert Hot Springs, CA with this @gmc Sierra 2500 on a set of @racelinewheels. These are the Raceline style 951 Ryno in the size 17×9 offset -12 bolt pattern 8×180. Note 📝 these will need a set of 14×1.5mm conical seat nut to properly install. If you’re looking for a similar setup feel free to contact us direct.
