Let's see... I've ran:
2 sets of old style Goodyear MTRs (265/75r16 and 37x12.50)
1 set of Goodyear MTR Kevlars (275/70r18)
1 set of Goodyear MTs (36x12.50)
3 sets of SS IROKs (2 sets of 36x13.50 and 39x13.50)
2 sets of BFG KM2s (255/85r16 and 35x12.50r15)
1 set of BFG AT KOs (275/70r18)
1 set of Nitto Terra Grapplers (285/75r16)
1 set of Nitto Trail Grapplers (295/70r18)
1 set of Nitto Mud Grapplers (33x12.50r18)
1 set of Toyo ATs (285/75r16)
1 set of Pro Comp Xterrains (38x13.50)
1 set of Continental Contitrac (275/70r18)
1 set of Michelin LT AT2 (275/70r18)
The best tires I've owned in ~300k miles of driving various vehicles are Nittos, in any flavor. I've been happy with them across several different vehicles. They're a bit spendy but worth it.
Just my 2 cents after running 17 different sets of tires over the years...
@rockcity - what load range is the tire that had the broken belt?
Also, the new Nitto Ridge Grappler will be out soon and it will be released in a Load F tire. I'll likely be putting those on the new Super Duty.
