I'm not sure I follow. 255 is the section width, and all 255s will be the same (excepting the usual variations from one tire make/model to another). The second number is a proportion to the first, so a 255/70 is shorter than a 265/70 b/c the "70" proportion is applied to a smaller number. BFG specs a 6.5-8.5" rim width for that specific tire so it should be within bounds. I'll check out the mudtech options!
