I've got the 305/70/16s on my Tacoma. They are wider than my buddy's 35/12.50/17 mtrs and taller than my old 295/75/16 Hankooks. They balanced out awesome and ride nice on the street so far after a week. I'll have a better report after the Summit next weekend.
This tire is incredible looking in person, my closest friends run the mtr, the Hankook Mt, and the Nitto Trail Grappler and they have all said they prefer the look and siping of the new Pro to their own tires.
Oh yeah, $70 rebate from Cooper right now also.
