Tire A

BFGoodrich All-Terrain T/A KO2

Positive

Community sentiment toward the BFGoodrich All-Terrain T/A KO2 is largely positive, with drivers frequently praising its aggressive styling, tough sidewalls, off-road durability, and solid general performance. Many owners report capable handling in snow, though several emphasize that it cannot replace a dedicated winter tire and can struggle on ice or packed snow. Criticisms center on high pricing, added weight hurting fuel economy, mud packing, occasional tread chunking, and difficulties with balancing causing highway vibrations.

“FWIW, I had the same 18s that you have and went to a 16" Vision Cross wheel and wrapped them in 225/70 KO2s. I weighed the stock wheels and the new wheels and the new set is only 2 pounds heavier than stock at most. I don't notice much acceleration loss, but I really don't beat on my jeep either. I did notice a little "hum" once I'm going 30mph but it's nothing annoying at all and I don't even hear it anymore. I have also carefully measured MPGs with both set ups and I have not lost anything. This is calculated MPG, not just what the computer says and I do add an additional 2.5% due to the increase in tire circumference. My avg is 25.1 (25.73 when adding the 2.5%) and my commute is 75% hwy and 25% local. I was afraid to get the KO2s because of added weight, tire noise and mpg loss, but I was afraid for nothing. Just my 2 cents, but I remember reading most people talk about how bad things would be with these tires. I'm glad I listened to those who said mpg loss would be minimal at most. Mike”

“I ran the stock AT3’s on TH for about 5k miles with no issues. They were quiet and handled sand, small/medium rock gardens and steps fine - though I was pretty concerned about punctures in the rocks. They were excellent in rain and surprisingly good in light snow which is pretty rare here in TX. I switched to 285/75/17 AT3’s because I wanted more rubber and contact when airing down. I’ve never run the AT4’s so I can’t speak to their capabilities. I’ve run BFG KO2’s, KO3’s and MT’s on other vehicles and they are excellent off road. The KO2’s and MT’s were not great in rain, but you learned how to deal with them. The KO3 is superior to the AT3 off road IMO. The downside being it’s hard to find load ranges other than E. That was one of the reasons I stayed with AT3’s when I went to a larger tire. I could get it in load range C, I was confident it could handle the off road conditions I would use them in, and they were excellent on road. The majority of my use is on road so I tried to be realistic and factor that in to the selection - not that I don’t look at a set of 35” R/T Pro’s and think “I Want That”.”

“BFG KO2 - 50k miles, some cracking between tread, slightly uneven wear. Time to replace? BFGoodrich KO2s on a 2021 F150 FX4 max tow. From what I can tell, these were the original tires and have just under 50k miles. Tread depth is technically OK based on the wear indicator. They show some cracking between treads, which may or may not be a problem based on the many threads and opinions here 😅 Bigger problem may be uneven wear. It looks like the original owner missed some regular rotations, and two of the tires (front when I bought the truck) were visibly more rounded than the rear. After 25k of regular 5k rotations it is maybe a little more even but still noticeable. They’re noisy - no surprise with with KO2s - and gas mileage isn’t great. I do tow occasionally - small travel trailer, 6x12 utility trailer, and rarely a pontoon. Time to replace? Or can I make it through another MN winter and replace next year?”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
