So here is what I ended up going with. I got system 3 sb4 beadlocks. Went with 15" wheel and did 3 - 6+1 (one for spare) and 4+3 on the back. This will be wrapped in tusk terrabite 10x15x30. 30 is big enough tire for me. The only thing I hope for sure is that I can run the 6+1 on the rear as a spare in case that is where I get a flat. I almost bought all 6+1 and planned on using a spacer for the rear. Did I make the best choice? btw...I don't plan on going bigger than 30".
