Silverado A/T tires/wheels

Question has probably been asked 100 times before, but for you tire/wheel guys: Looking to put some A/T's on a 2012 Silverado crew cab 4x4. I'm not looking to jack it up, or max the tire size, since it's 75% highway miles, just looking to get the G/Y Eagles 275/55/20 off and a set of A/T's on it. I've always run BFG A/T's on my Silverado's but with 17"/18" wheels...



What to do with these 20" stock rims? Pics?
