The K02s were installed on our Ram 1500 4X4 about 10,000 miles ago. We drive it primarily on road but frequently off road on Mojave Desert trails. We bought them because we like the K0s on our vintage Jeep. These tires are exceptional both on and off road. They handle better on road than I imagined and did not change the fuel mileage at all from the stock street tires. My biggest concern before buying them was sound (we do a 500 mile road trip to monthly) but I needed tires with off road capability. The only time I notice the sound is while braking and it isn't annoying. Off road performance is everything I hoped and more than we need. Flats were my main concern and so far so good. The real test for the tires was on a 70 mph section of Interstate 10. My wife had nearly passed a big rig when the driver weaved into her, his left front wheel with lug nut spikes contacted her right rear. She felt the nudge and got the truck to the shoulder across three lanes of traffic without spinning or losing control. The spikes took chunks out of the wheel and broke the bead resulting in a total loss of air pressure. The sidewall of the tire was sliced but when we looked at it the carcass was not penetrated. The tire was not punctured and would still hold air if there wasn't a hole in the wheel. My wife said after correcting from the initial impact the truck handled predictably the entire incident. We'll put T/A K02s on all our future trucks as long as BF Goodrich makes them. Thanks for a great product!

I bought these tires less then a year and a half ago, I put 23000 miles on them and they need to be replaced already, very disappointing. The stock tires that came with the truck lasted almost 30000. These tires also do not come with a milage guarantee.

LT285/70R17, '10 Tundra: *Poor wear patterns - Rotated Every Oil Change. *Aligned Truck once every Year. *Had to use 4WD any time it Snowed - No Traction. *Noisy. *Sidewall Dry Rot. *Expensive. *Replaced Tires with 8/32nds tread still remaining. *Suspect Tires would have lasted about 50,000mi. *Did not off road. *BAD TIRES.

Have been a loyal customer for years and loved the looks of these tires. They have performed well on the street but suffer on the sands of St Augustine Beach. Couldn't believe it at first but the tires sink in the soft beach sand easier than my Michelins did. I now know why, they are smaller than the Michelins even though they are stamped the same size. Disappointed that they are so much shorter and narrower than other tires with the same size stamping. If I buy these tires again I will compare sizes first.

I also forgot to mention on my first review, that my truck is not lifted. I am running air bags in the rear only to help with leveling the truck when the trailer is attached. I noticed that odometer/speedometer, stock from Ford, were off a little. So after plowing through the stock Conti's at 275/70R18 (50,000 miles), that's when I upgraded to the ALL-TERRAIN T/A KO and eventually the ALL-TERRAIN T/A KO 2 at 305/65R18. This not only corrected the odometer/speedometer, but also gave me a more confident ride.

Bought these tires 3 years ago. They've seen 11 Western states, 5 National Parks, and 3 Wildland fire seasons. I've traveled solo as well as with a 5th wheel RV in tow. There is still almost 40% tread left with no chunking. I will buy these tires again if they ever wear out/

I had this tire in previous years in the KO’s and recently KO2 in 35" & 37" on a Hummer H1 - H2 - H3 and recently 285/70/17 on a Toyota TRD Off-Road premium. I had this tire on my Hummer H2 for 87000 miles with off-roading (Rock-Crawling & Hunting) never had a flat with any of them. Excellent in all weather conditions; hence, for heavy snow we need snow-tires & for Ice we need Ice-Skates, no such a thing as Ice-Tires. This tire is very good on Freeways & City driving not noisy. I see a lot of people complaining about tread-wear; Bf Goodrich should mention that alignment is important and most tire wear comes from miss alignment, toe, caster & camber; which you might not be aware of. Hence, I highly recommend this tire. I have no affiliation in any shape or form with Bf Goodrich, this is just an honest review.

Let's put it this way, I've owned several GMC 2500's and used the GOODRICH T/A since 2002 and would not run anything else. I used to pig hunt hard and these tires put me in places others simply could not get. I was the guy they would come to get to pull them out. I drive long distances and these are as quite as any other tire, I drive in ice and these are like glue, pushed lots of snow and NEVER got stuck. This is the tire I will use the rest of my life. On fuel mileage I wouldn't know, won't use another tire. Rob

Liked everything about the tire EXCEPT it wore out at 27,000 miles. Had them on my 1997 F-250 4x4 diesel pickup and the dealer said the heavy pickups eat up the soft rubber. Went to a tire with a 60,000 mile warranty as the KO2 has no mileage warranty.

I have a set of these tires on my 2008 Dodge Ram 1500 2 wd. I have low mileage on the tires and the tread is almost full. My problem is that they have just started making a terrible noise. I would like to know if anyone else has had this problem.
