I've owned KO2's which were outstanding, and now have upgraded to the KO3's and so far this is a great product. I would expect nothing less from BF Goodrich Tires.

These BF Goodrich K03 tires are an upgrade from the OEM Bridgestones that came with the car. They handle well and contribute very little noise on the highway.

After my KO2’s wore out, had a new set of KO3’s installed on my truck at the dealer where I bought my truck. Been back twice and they will not balance. Terrible vibration at highway and interstate speeds. Very disappointed!

Grips to the road like glue, only tried it on wet roads and some ice but expect goodness in snow too. My old KO2s lasted 70k miles so i expect these will likely hit at least 60k. Rides quiet too

Simply put, most all of the 1 star reviews seem to be from people with newly mounted tires that have balance issues. A good tire shop familiar with BFG's and 8-12 ply tires is a must. These need a good quality Paste (lots of it) when mounting to ensure a bead seal and also road force balance (without rushing thru it because they are a trying to max the number of tires sold that day). I spent quite a while in the shop waiting and watching the install, but it was worth it. That said, all Tire Companies sometimes have an imperfect one come off the line, but in that very rare situation a good shop will spot it and stop the install and order a replacement (not put it on anyway knowing it was not right). I have had no issues with mine at any speed and I love the grip, low road noise and overall feel of these tires. Plus, they look super cool ! Very happy with my choice and confident they will last for years.

Mounted on 2021 gmc at4 hd. Tires have enough weight on their to fish for a lifetime. Had them balanced twice and one roadforce balance. Same issue. Vibrates in rear. steering wheel wobbles. So its more then one with a issue. Ruined a 100k truck that drove like a dream with the factory goodyears now has a massage feature throughout every seat. Terrible tires ad bfgodrich should reimburse the customers.

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.

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:

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.
