Are you studded and O-Ringed?....

If so then I would reccomend the 5x.014's.

If your not then I would not go much bigger than a 5x.012 as the added pressure will certainly make for a quick headgasket exit.

5x.014 most people will never need anything bogger than that, even 5x.012 will work good. There's a post on CF now about a guy running low 11's on 5x.012's.

I would also recommend the 5x.014's as Hammer stated if its studded and o-ringed. Makes for a great combo and a fun truck to drive.
