I am about to install a 6" Rough Country lift kit on my 2015 Ram 1500. The one thing I really don't know anything about is the wheel offset. I don't want my tires sticking out super far from the truck. Basically want it in the wheel well as much as possible. I want to get the Fuel Vapor rims, with Nitto Trail Grappler tires. I just want to make sure I get all the right parts. Any help or advice would be appreciated.
