I've also heard the comment on Rams and BFGs wearing out, it seems to be shared whenever a tire recommendation thread comes up on HD ram forums. Tires are always evolving though. I'm looking forward to hearing the first hand experience and mileage you get based on that brand new set.
Speaking of larger tires and to start another conversation, anyone have any thoughts/options on running 39/40s without having to do AEV fenders? I don't want to change lifts from my Carli backcountry, but we all want to plan that larger set. These trucks wear 40s like my old solid axle Toyota wore 33s, it just looks good. There are some other front fenders available and I think the rear would have no issues clearing 40s.
