Curious about this as well. I am thinking of putting a set of escalade 22 inch wheels on to replace my stock 18 inch. Wheels themselves are both a 22x9 with a 6x5.5 pattern. What I am wondering is the offset and center bore. GM wheel offset is +28, Ram offset is +19.05. GM center bore is 78.1, Ram center bore is 77.8. At this time I can not find a hub ring to make up the .3mm difference in center bore, any thoughts on that? Also will the offset be ok for clearance? I will go with the factory 22 inch tire size used on Ram.
