I stumbled upon a set of 35x12.5r15 KOs for an unbelievable price. So, I jumped on them, and so far have been satisfied. I have only run BFG and Interco tires over the past 13 years - faithfully. The BFGs have their strengths (price, availability, balance really well). The Intercos also have theirs (ruggedness, superior traction) but also lack the ability to balance and howl at hwy speeds.
As for the BFG brand - I have run both the KM (not the KM2), the All-Terrain (1 set) and the All-Terrain KO (on my 2nd set). In the desert, I destroyed 1 KM tire (new) and 1 All-Terrain (pre-KO tire).
Ford Ranger - Big Bear, 2002 (rear set All-Terrains, front set KOs) 4.56s, open diffs
I wasn't very happy with this configuration after running a set of bias-ply TSL-SXs (32") and no locking diffs. I almost lost it near a cliff behind Mike's Sky Rancho, and I can only blame the truck and its' poor traction (and the tires). I sold the truck 2 yrs later, so who cares.
'03 Jeep Rubicon - Joshua Tree, 2005 (plugged Interco spare being installed on the trail)
Laguna Salada Creek Crossing - Baja, Mexico
This is what sold me on the 35" size for the KO - I crossed this muddy section with the rear air locker helping push me through. Big Thumbs up!
Russ with 33" KM2s pulled through with no issues through the same creek crossing (did I mention this is a salt water creek?)
Our tires were caked with mud, but everyone was running BFGs, and nobody needed a tow strap.
On the highway, the Jeep isn't noisy like it had been with the nearly bald set of Interco TrXus MTs I had been running. Handling is great, as is braking. MPG is almost the same (w/4.10 gearing) as with my 33" Intercos - which I consider to be a plus! My only long-term concern will be that of durability on the trail - because, I run my Jeep all day and into the night DEEP into Baja where tires are known to give up.
