Does anyone have any idea how much lift it would take to get 46" tires under a M715? I have also read that 40" tires will rub but is that if they are mounted on offset rims? How much offset is needed? I ultimately want to put the biggest tires I can under my M715 will minimal fabrication and keeping the cost down as much as possible. I am leaning towards 40" but I am not sure how much more it would take to go bigger!
