265/70/17 ridge grapplers. Requires modding the pinch welds and a lift kit which it looks like you have done. The 265/65/17 does not require pinch weld mods and will fit in the spare tire area but not the 265/70/17, that's why I went with the smaller tire. How much wobble does the wilco have? That's the main reason I have not bought one, I think it would wobble too much when driving down trails.
