Previous tires were KO2 on a F250. I do small amount of off-roading but mainly around town and towing travel trailer. Installed new KO3 7K miles ago. Since then very noticeable amount of sway when towing. I have a Pro Pride hitch which eliminates sway caused by wind on the trailer, so sway that was not present with KO2 is now very uncomfortable with KO3. Do not purchase KO3 tires if you tow RV. Wish I had my KO2 back.

I owned KO2’s on my 2021 Chevy Trail Boss LT and I loved them. Great wet traction and stopping power. Main reason I bought them was for winter driving and they did not disappoint. Just bought a new 2026 LT Trail Boss that came with mud tires. Heading for the ADK’s in upstate NY the end of January. Upgraded my tires to KO3’s. They look like they will do the job in the ADK mountains, snow and ice… I already feel more confident in tackling that weather!

Bought a full set of 5 for my truck, was very excited after seeing reviews compared to other brands in the same class. Had them delivered mounted and balanced on a new set of wheels and tires from Tire Rack. Put them on the truck, made it about 2min down the road before I felt vibrations. After hours of back and forth with TR and hundreds spent on balancing and road force, they still couldn't be balanced. Infuriating and disappointing. I returned them and swapped to a different brand in the same class and they run absolutely fine, as do the factory set.

I recently put BFGoodrich All-Terrain T/A KO3s on my truck, and they’ve been excellent — especially in winter conditions. Snow & Slush Performance: The KO3 tread pattern and biting edges really help in snow. They dig in well and maintain traction even in deeper, unpacked snow. I’ve had confident starts and stops without feeling like I’m slipping around. Ice & Cold Grip: While no all-terrain tire will match a dedicated studded winter tire on ice, the KO3s perform surprisingly well for an A/T. The rubber compound stays pliable in cold temperatures, and I’ve found grip on slick, icy patches better than I expected. Wet & Slushy Roads: The wide, deep grooves evacuate slush and water effectively. Hydroplaning hasn’t been an issue even in heavy wet conditions — which gives peace of mind on winter highways and back roads. On-Road Comfort in Winter: There’s a bit of road noise compared to a highway tire, but they’re stable and predictable in cold weather driving. Ride quality has been solid on both dry and snowy pavement. Off-Road Winter Trails: On snowy dirt roads and forest trails, the KO3s have been great. They bite into uneven, snowy terrain and hold their line well. I’ve felt confident on hills and loose surfaces. Wear & Durability: After winter miles, I’m seeing even wear and no unusual signs of degradation. BFGoodrich says the KO3 compound is built for longevity, and that seems to be true in cold weather as well. Pros for Winter:

These tires are top notch worst I have put on a truck. Engineering from the original KO’s appears to have been negated. Reduced tread on the road. No longer a shoulder protection of sidewall. No longer is the tread square for shoulder to shoulder at all pressures. The tire now crowns after 50 psi on a load E tiire.KO 3 are junk just like KO 2. go back to the original KO design! I retained my original KO to compare.

These tires are the worst tires I’ve ever bought. They’re dangerous in wet snow and ice. Last night on our way home the road was wet and the car in front of us slammed on their brakes to make an illegal turn. So I had to slam on the brakes and almost smashed into the back of them because the tires just slid. ABS was going crazy. I wasn’t too close to the car but because of their unsafe decision to stop and turn in the middle of the road it almost caused and accident. I originally went with these becase of the reputation of the KO2s. I heard that these were supposed to better than the KO2 and from everything I read on the forums and the reviews here and my personal experience I’d highly HIGHLY recommend against these tires. I’m very disappointed I spent my money on them and have to wait until I can save for a different set because we waited so long. But we got them at the end of the spring and didn’t experience them in wet traction until fall so we were well outside the 60 days by the time we experienced how crappy these are. If I could sue BFG for how horrible these are I would in a heartbeat.

I had the KO2s on my 2020 Chevy Silverado Trail Boss and absolutely loved them, so my expectations were already high. I recently put the new KO3s on my GMC Sierra AT4, and honestly, they impressed me even more than the KO2s. BFGoodrich really stepped it up with these. The KO3s have amazing traction in every condition — rain, snow, dirt, and even just everyday highway driving. The steering feels tighter and more controlled, and the ride is smoother than I expected for an all-terrain tire. They also look great on the truck, with a more aggressive tread that still stays quiet on the road. I was already loyal to the KO2s, but after running the KO3s, I can say they’re a serious upgrade. If you’re thinking about all-terrain tires, these are worth every penny. Highly recommend them for anyone who wants performance, durability, and a great look all in one.

Have not had my KO3 very long, but have had many KO2 and Good Year Kevlar. When going in from the standard soft dealership tire to a 10-ply tire, people automatically notice the stiffer ride and increased road noise. This is expected. When driving home after having these KO3 tires installed, the first thing I noticed was, when hitting the usual bumps in the road, the ride was much smoother than before. Thinking this cannot be true, I asked my wife what she thought about the ride (believe me, she knows nothing about tires except they turn when driving). She said (no lie), “It’s much better than those other tires you had.” As for road noise, the last set of 10-ply tires I bought, the first thing I noticed was road noise. I never noticed any increase in road noise. If anything, they might be quieter.

With approximately 20,000 miles of use, these tires have developed pronounced cupping, severe uneven tread wear, and chronic balance issues that materially affect ride quality, noise levels, and highway safety. This deterioration is far outside what any reasonable consumer should expect from a premium all-terrain tire marketed for durability and long service life. The tires have been maintained to a standard that eliminates typical user-error explanations. Tire pressure has been consistently maintained within BFGoodrich specifications. The tires have been professionally balanced and rotated at 5,000-mile intervals. A professional alignment has been performed and verified to Thuren Suspension specifications, which fall well within acceptable parameters for both on-road use and tire longevity. Suspension and steering components are in proper working order with no abnormal wear or mechanical deficiencies that would explain this pattern. Despite this, the tires are now extremely difficult—if not impossible—to balance properly. Road noise has increased substantially, and visible cupping is present across multiple tires, indicating a systemic issue rather than an isolated defect. The uniformity and progression of the wear strongly suggest a defect in construction, internal belt integrity, or compound consistency. Of particular concern is that this experience is not unique. A review of publicly available consumer feedback reveals a significant number of similar complaints describing premature cupping, uneven wear, and balance instability with the KO3 model. This establishes a documented pattern of failure. To date, BFGoodrich has not issued a recall, technical service bulletin, or public acknowledgment addressing these recurring defects, despite what appears to be ongoing constructive notice. For a tire positioned and priced as a flagship all-terrain product, this level of performance at only 20,000 miles is indefensible. The condition of these tires represents a premature loss of value and raises legitimate questions regarding quality control, product testing, and corporate response to known issues in the field. I purchased these tires in reliance on BFGoodrich’s reputation for engineering, durability, and accountability. Based on this experience, that reliance was misplaced. Absent a meaningful response or corrective action, I cannot recommend the KO3 and would caution prospective buyers to carefully consider the growing body of evidence indicating premature wear and balance defects. BFGoodrich should treat this matter seriously. The consistency of these failures across multiple consumers suggests an issue that warrants formal investigation and corrective action, not continued silence.

Issues with 315/70R17 F rated tires I recently got: 1. Cosmetically, there's quite a bit of flash on 3/4 tires. Not something I notice typically, but it's bad which makes me question manufacturing of these. 2. 2/4 tires took over 10oz of weights to balance. My previous KO2s on the same rims took less than 4oz. 3. Even with road force balancing, they still vibrate more than my KO2s. 4. Road noise is similar to KO2s. 5. Wet traction is why I bought these and they seem barely any better than the KO2s they replaced, which were pretty bad in wet/slush/ice. 6. They did great in the snow. Swapping them out for D rated ones in a few days. Hopefully that solves the balancing issue. Guess I'll just deal with subpar wet performance.
