I was actually alittle confused about that, but I have no first hand experience with that size tire. I figured that an 8" wide rim was waay to thin only because a 12.5" wide tire is 4.5" wider than the rim, which to me seems alittle ridiculous. Now that I know, I'll probably will go with the 8" rim (I like the look of a wider tire on a thinner rim anyway). Thanks again for the suggestion(s) Eric. I'm excited to finally lift the jeep after learning about everything invovled in going this big.
