I am in the process of buying new wheels and tires for my 2012 2500 and was wondering what is the most offset I could get away with? On my 2011 1500 I ran a 5" back spacing with 18x9 wheel with 325/60/18 tire and I loved the look. I am wondering if I could get buy with that or do I need something different? By the way thats the size of tire I am going to run on my 2500. I dont know how much difference there is in the offsets in axle's from the 1500 to the 2500.
