To me P265 70 17 AT3 provide far too much overall performance AND value to make the switch. But I am always looking for Plan B!
That is 255 75 17 Firestone Destination MT2.
The reason: it is super light for an MT (46lb), yet has a 3-ply sidewall and it is also C load. What is there not to like? Well, the price though that is secondary. The other reason is that the At3 just does so well. I would not mind a deeper starting tread than the P metric At3 but the MT tread will surely not last any longer. I project over 30,000 for my AT3 despite above average offroad use. I will be shocked if any MT can last longer in my use.
The reason I am not interested in Wildpeak MT is 1/weight 2/the Falken website clearly ranks the AT3 as much better on road.
Realistically, for those of us in AZ and SoCA I don't know why we are even looking at any MTs for anything short of a dedicated rock crawler that drives on the sidewalls when squeezed and needs a winch to get over crazy boulders. Mud is easily avoided and [MENTION=140439]Decipher[/MENTION] has found the AT3 surprisingly capable in mud (as capable as an RT tire).
