That is a tight squeeze, hope you don't get snow/mud caked in the wheel well, it might spill out and scratch those pretty painted cladding pieces! You should have chosen the gray cladding, which is more durable and doesn't show scratches as much.
Your rig looks good, just picked mine up last friday, and I want to upsize my current 17" tires with Goodyear MT/R. The one additional size really made the rig looker beefier. I personally like the gray cladding, but hey, we live in a free market economy and if your tastes are different, somebody has a product to sell you. I am concerned about the stock trailer hitch, having enough depth with a bigger tire underneath.
