I went through the same questions and concerns regarding tire size and what will look awkward with a 3" lift. I was totally worried about my tires being undersized. I even went tire shopping and got a few quotes. I ended up holding out and I'm glad I did (I got a bumper instead)

. My FJ looks pretty good even with the BFG's. But that's just my opinion. I do plan on upgrading but figured id save a few bucks for now and wear these out first.
Oh, i did install 1.25" spacers to add some width. Cheers....
But to answer your true question with that large of tire you will need a BMC for sure, and probably more. I'm not an expert though just a fjcforum reader and addict.
