I have a 2006 GMC Sierra 1500 SL 2WD with 6 bolt 17 x 7.5 rims. For winter tires I am considering buying 6 bolt 16 x 6.5 rims from GM, which are OE on 2004 Silverado 4WD 1500. Can someone confirm that these rims will indeed fit my truck? BTW all the rims mentioned here are the basic steel rims. Thanks.
