Tire size question?

I know this has been asked before but......

What would be the ideal tire size for a Double Cab 4x4 w/ Toytec 3" lift, TC UCA's, and spacers on stock 17" TRD Sport Wheels? I don't mind trimming but I don't want any rubbing. I mainly use my truck for day to day driving back and forth to work but I will be starting to do some offroading on the weekends. I'm leaning towards BFG Mud-Terrain T/A KM's but I am open to any other suggestions. Thanks in advance fellas.

p.s.
I did use the search function before I asked but I couldn't find a similar question to mine.

 

285/70/17 or 285/75/16.

Did you guys lose much power going to 285? I put 285's on my old Hummer H3, and that made a big enough difference in power and mpg that I wish I had stuck with the 265 -75 16. I don't want to make the same mistake on my new truck, and am almost a little nervous going to a 265.

 

Very minor power loss. But I do plan on regearing in the future. Not in a hurry. Plus it's been almost a year. Maybe lost 2mpg tops. Maybe 1.5. Idk.
