We put the new BFG KO2's in a 265/70 R17C (6ply) configuration on our stock 2003 Toyota 4Runner 4.7L v8 4x4 with 17" stock alloy's and have run them for just about 3500 miles running at 50 psi and have been very pleased with them so far. The size is a slight up-tic from the stock tire, but is the size recommended via a call to Michelain's customer support help-line. The clearance in the front wheel well when the tire is turned hard right or left leaves about and inch against the interior well trimming. We have not had any rubbing or collection of debris trapping therein. We chose the C class feeling it would be a good compromise given the GVW of the V8 4runner and our intended use and all-around passenger comfort as opposed to the E class 8Ply configuration. We bought the 03 4.7L V8 4x4 (108K miles) because we wanted an old school rig we could go into the hills with and not worry about putting some Colorado pinstripes on while four-wheeling through tight tree lined tracks, tow a trailer if needed and run the interstate to Denver from our home in South-Central Colorado. So Far - Very Good! Both the Rig and the Tires. We've never enjoyed, or been impressed as much with a vehicle as much as this old V8 4Runner and the BFG KO2's have simply improved the vehicle which previously had a set of Michelin all-season radials. I was very concerned about road noise with the KO2's, but decided that we were going all in for them in that we wanted a tire that would serve better, the purpose for which we'd bought the rig. These tires are amazingly quiet! And I'm terribly picky and sensitive to road noise. In my opinion their noise increase over the all-season Michelins is so minimal as not to be noteworthy. As for performance, in November we took them for a spin up the rough and rocky 4X4 track which leads to Balman Reservoir and Rainbow lake in the Sangre de Cristo Mountains. We aired down to about 30 psi and were very pleased in that we weren't getting beat up by the 6ply's - this is a rough and very rocky road and the tires performed very well in dry, steep and steep track with loose gravel-scree and dirt. At higher elevation we ran into snow (perhaps 3" to start) and the tires did a great job their too. The only slippage was as we climbed in steep turning pitches where the rear end would slip a few inches out to the downhill side. Mostly due to the tracking of the trail itself. We stopped and turned back due to good sense and an extreme narrowing of the trail with a precipice on the right-hand downhill side of the track. The tires were willing; we on the other hand decided that in the fading light of day, good judgment and not the voice of the KO2's saying go for it was best. Also, upon returning to lower elevation and groomed dirt and pavement we did not observe and tire damage nor did the tread retain and gravel or rocks of any significance. - So Far- Very Good! On the highway we have enjoyed a confidant ride that does not pull or cause the vehicle to behave any differently than when we'd previously driven it on the all-season Michelins, a great tire for what they are designed to do -. As for fuel economy, if their is a negative it is negligible in that we've not noted any loss of merit in our mileage per tank - So Far - Very Good! As for paved roads and snow and ice, just last week on Saturday afternoon we happened to be obligated to drive in conditions that one would otherwise be advised to stay home and read about such adventures by a warm fire. It was Saturday, December 12th, the condition were snow, packing snow and straight-up skating rink (I've got 20 sliding, crash, ding and dent photo's to prove it!) You know, the footage you've seen scenes like it on the evening news people sliding while simply setting still - yah that stuff! The BFG KO2's were fantastic! I did put the 4runner in H-4 (four-wheel drive and but with the exception of those hard right or left turns in a tight circumference radius turn where the rear-end would give a bit of side-slip out and then recover, they instilled confidence and proved themselves a tire that, I will, without hesitation buy again and highly recommend to others.I gave the tires a 4-Star rating here as opposed to a 5 only in that we have not had them long enough to determine rubber compound longevity, overall durability and/or tread-live etc.,. All said, if you're thinking about a new All-Terrain or Snow Tire go buy BFGoodrich's All-Terrain KO2's, they will not disappoint.
