It will depend on what you are planning on doing to your truck. Are you going to lift it or leave the suspension stock? To you want the wheels and tires to stick out or remain tucked under the vehicle?
For now I am just looking at keeping the stock suspension. At the end of the day I just want what I order to fit but if the wheels stick out little, that's a bonus. Everyone on this site has me super paranoid about wheels clearing the calipers.
Yeah, the calipers on this truck are a pain for sure. Are you going to use your stock tires or are you planning on upgrading those as well? What finish do you want your new wheels to be? We may be able to make some recommendations for you and save you some trouble.
I can recommend some offset ranges to look at but, unfortunately, it won't eliminate your chances for the wheels to hit the calibers. That all depends on how aggressive the back of the wheel's spokes curve. The best bet for that is to find a wheel you like in the correct bolt pattern (6x114.3) then call the wheel manufacturer and ask if they have had any issues fitting your truck. You can also search this site for others who are running them or who have tried to run them.
