I'm doing the same as you. Just purchased a Teraflex 2.5" lift last night. I am going with Nitto Trail Grappler 35/12.50/R17 tires on Rugged Ridge black satin wheels. I picked up the Teraflex HD hinged tire carrier as well to handle the additional weight of the tire. I personally think the 2.5" lift and 35's are a great looking combination.
also, I'm installing an AEV geometry correction bracket and the Teraflex monster HD forged adjustable track bar (both to give me better on-road driving)
since your vehicle is a 2012, you "may" need an exhaust spacer.. something I've read bout on the forums, and don't forget a Flash Cal to reprogram your rid to compensate for the larger tires.
