The best thing you could have done, was to think about this BEFORE you purchased the truck. The 3:73 gears are a bad choice for a running larger tires. And most that go to the trouble of lifting a truck, want to cap it off by installing larger tires. Their is nothing you can do about the gears now (of-coarse you could change them out, but it is expensive and you most likely don't have deep enough pockets, you chose the Tuff Country lift which is the cheapest both in price and component selection), just stay on the smaller side with the tire selection. Some lifts require that a minimum back space be run, I don't know about yours but you might want to check into it. The aftermarket wheels up to you and your budget. For a unique and different look, the stockers won't stack up, also a wider wheel may be necessary depending on which tire you decide to run. You pretty much have decide on that one by yourself. Don't forget to add a good steering stabilizer to the budget, they are almost a most with the larger tires. Good luck and post your results.
