The BFGoodrich All-Terrain T/A KO3–AKA the "BFG KO3"—is the 3rd generation of BFGoodrich's legendary Off-Road All-Terrain light truck tire engineered for the on and off-road tire needs of dedicated off-roaders like Jeeps, pickup trucks and 4x4 sport utility vehicles. It's built for drivers who want rugged confidence and control no matter where their journey takes them. Following up the wildly-successful All-Terrain T/A KO2, the KO3 has been carefully designed to retain the aggressive (and classic) visual elements of BFGoodrich all terrain tires, while delivering outstanding durability, improved wear-life and traction in all weather conditions—even light snow.

Available in LT fitments, load ranges, and sizes beyond 35 inches, the KO3 features a reformulated cut, chip, and tear-resistant tread compound for greater longevity and durability. Molded into a symmetric footprint designed with a generous amount of void for off-road use, while also optimizing the footprint for more even stress distribution and uniform wear. The interlocking tread blocks are designed to work in concert with one another for stability both on and off the pavement. Broad channels at the shoulders and plenty of void space to redistribute water help maintain control in the wet. The 3-D Locking Sipes are full depth and alongside the Snow/Mud notches, are designed to help drivers find the traction they need in any environment.

The upper shoulder and sidewall feature CoreGuard Technology: a bruise- and split-resistant rubber compound that extends further down the sidewall to protect more of the tire in demanding scenarios. Alternating Shoulder Scoops deliver clawing force for control and traction in sand, dirt, or grueling off-road rock driving during "aired down" adventures, while the Mud Phobic bars keep the tire clear of built-up material so it can perform as intended. And as always, the KO3 is available with raised white sidewall lettering—perfect for making your tires and wheels pop, complementing your truck's paint, or making your classic 4x4 look the part.

Internal construction of the All-Terrain T/A KO3 utilizes a durable, triple-ply polyester casing designed for strength and reliability, along with twin, high-strength steel belts providing a robust foundation for the nylon cap ply offering high-speed capability.

NOTE: BFGoodrich All-Terrain T/A KO3 tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.

...These handle really well on dry or wet pavement, have a lot less noise than I was expecting with the aggressive tread pattern, and have just proven to be a solid all around tire - until you get on snow or ice...

I've had this tire on a 2006 Ram 2500 (load range E 10 ply) for the past 60,000 Minnesota miles. They still have a 6/32" of tread, though I run on gravel roads a lot more often than most people. But this is still almost double the miles I got from my last set of tires. Here's my take: These handle really well on dry or wet pavement, have a lot less noise than I was expecting with the aggressive tread pattern, and have just proven to be a solid all around tire - until you get on snow or ice. Then they're bad. I think Cooper must have used a really hard tread compound that sacrifices cold weather performance for longer life. I don't think I'll get these next time because I live in MN, but I would definitely get them again if all my driving was in a warmer climate.

...Even though those still had plenty of tread left on them, I couldn't trust them after three separate hydroplaning events at very slow speeds. Hydroplaning can easily happen at high speed on any tire, but when you are driving cautiously through heavy rain at slow speeds and you are still hydroplaning, the tires need to go...

I had these tires put on three months ago. I do mostly city and highway driving but I wanted a heavy duty tire that handled well in all conditions without excessive road noise. These tires were a great find! I have been very pleased with the construction and overall quality of these tires. Cooper did an excellent job designing and testing these tires for truck use.
My previous set of tires on my truck were Firestone Destinations. I was very unhappy with how those performed. Even though those still had plenty of tread left on them, I couldn't trust them after three separate hydroplaning events at very slow speeds. Hydroplaning can easily happen at high speed on any tire, but when you are driving cautiously through heavy rain at slow speeds and you are still hydroplaning, the tires need to go.
These Cooper tires feel like they are bullet proof. American made,10 ply rating, rock removing tread and they weight 50 lbs a piece. Sure, these tires hurt your acceleration a little, but they're grippy, provide good traction and they aren't noisy. I'm hoping to have several years and many many miles out of these tires.

Pros: Quiet, Tough, Heavy, Grippy, American Made in Arkansas

Cons: Ride a little rough, probably due to all of the tread, not a deal breaker for me though
Mileage suffered a little, but it's worth the good handling in bad weather

...The most snow Ive ever had them in was about 14 inches and they gripped and we plowed through the snow with hardly any problems. Ice is the only situation wherw these tires aren't great, but that goes for a majority of the tires on the market anyway...

This is the 2nd set of these tires I've bought. I got just over 70k out of the first set, ran them at 45psi and rotate and balanced them at every oil change. They did so well, I got another set. I have over 40k on them and they still look fairly new and still ride good. They aren't as quiet as the Michelins I had on a previous truck, but for a AT tire, they aren't awful. I mostly drive country roads, gravel roads, some highway, some mud, and through rain and snow when we get any. I will say 99% of the time these tires grip and go, and rarely slip. The most snow Ive ever had them in was about 14 inches and they gripped and we plowed through the snow with hardly any problems. Ice is the only situation wherw these tires aren't great, but that goes for a majority of the tires on the market anyway. If we get ice, I usually don't have to drive anywhere anyway so its ok. Otherwise, they are great tires and I will keep buying them.

...Immediate steering respond improvement, traction in all conditions, and ride comfort especially on rough roads...

I had the GY wranglers from the factory just so you know what my comparison point is. That being said, there is no comparison to the AT3s. Immediate steering respond improvement, traction in all conditions, and ride comfort especially on rough roads. The only, and I mean only, downside are the inherent changes going from an all-season to an all-terrain tire. A slight drop in fuel efficiency (<1 mpg) and a little more road noise. Stable, dependable, and worth every penny.

...Good traction all around, even when you put it in sport mode and stomp on the gas. Can feel a bit squishy in corners, but never lost traction...

Overall a great choice. Quiet ride in all conditions - really noticeable when driving on ground-down highway between these tires and other vehicles. Good traction all around, even when you put it in sport mode and stomp on the gas. Can feel a bit squishy in corners, but never lost traction. Did notice a drop in MPG (about 2) after changing from the stock all-seasons that came with the truck. Treadwear is a bit iffy - have some odd center wear like they were severely overinflated, even though I'm religious about maintaining proper inflation and alignment. However, did a lot of heavy towing recently so I'm going to blame that. Definitely staying with Cooper AT3s.

...I rotate my tires every 5k and the wear pattern is perfect. AT 45k my last tires would have barely passed state inspection, but they would have passed.

This is my second set of tires. My first lasted 45000 ( however they were only rated to 40K at the time ) These are rated to 60K ! must be a new tire compound. I had no issue with them in the Pennsylvania winters before, and expect the same with these. Being a light truck tire - they are not quiet, but not over noisy either. At highway speeds the radio easily drowns out the road noise. I rotate my tires every oil change (5k) and the wear pattern is perfect. AT 45k my last tires would have barely passed state inspection, but they would have passed. I purchased new ones due to a planned vacation trip to Florida ( 2500 miles in a week ) and just wanted the peace of mind. You will be happy with these, I know I am !

...The tread wear is PHENOMENAL and there is ZERO road noise from these tires! I saw a review that someone got 100k out of these tires. I expect to get close to that...

These tires are FANTASTIC! I drive typically at relatively high speed (80+ MPH) on the highway. I have hydroplaning issues exactly twice in 30,000 miles and that was from deep ponding on the roadway. I slid a little with light snow over ice coming to a stop. Deep and light snow wasn't an issue except for the snow over ice storm. The tread wear is PHENOMENAL and there is ZERO road noise from these tires! I saw a review that someone got 100k out of these tires. I expect to get close to that.I drive fast and live in the pothole capital of the world, NJ. Off road they are great too. Not perfect for every terrain but also not bad at all terrain's. Air down/air up and they will get you out with some throttle input. I wanted BFG AT's but they weren't in stock in my size at the time of purchase. I am absolutely NOT AT ALL disappointed in these tires. I am going to get a set for my daughters 4 Runner! I can not say enough good things about these tires. PS; I have Load Range E 265/75/16 on a Tacoma compared to stock (base model) 245/75/16. They fit perfect and do not rub.

This is the second set of these tires I�ve had on this truck and am about to buy a third set. If you keep these tires rotated as I have they will FAR surpass their warranty mileage. My first set was ran for quite some time on bad ball joints as well and still cleared the warranty mileage. No road noise, good in snow, I do a lot of towing and just haven�t had one complaint. I was always against Cooper tires because of one past bad experience but as far as light truck tires go this is the only tire I�ll buy. Great value for the money!!
