From the Owner:

Check out our customer Robert from Destin, FL with his @gmc 2500 on a set of @ultrawheelcompany wheels. These are the Ultra 203 Hunter in the size 20×9 offset +18 bolt pattern 8×180. Note 📝 these will need a set of 14×1.5mm conical seat lug nut to properly install. If you’re looking for a similar setup feel free to contact us direct.
