“I ran a set of 295/70r18 Discoverer AT3 LT’s for about 25k miles. I had seen lots of negative reviews but figured that I would be OK with them for my needs ( I drive in snow 4 - 5 times per year). Initially I was happy with the tires as they performed well in the snow and the rain but after 10k miles they developed a balance issue and started to wear irregularly. I had never experienced anything like it before. I actually purchased new shocks but never installed them. As I drive a lot of miles I just never had any time to deal with chasing the vibration / balance issue and just replaced the tires with Bridgestone Dueler AT Ascent. I now have about 20k miles on the Bridgestone’s and they are still ride very smooth and are wearing great.”

Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
All-Terrain T/A KO2
Discoverer AT3 LT
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
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.
“I like mine so much I'm on my second set. I got 55k out of my first set (could have got another 10k but started to get a little noisy). Exact tire you have (265/70-17 C load) on a 2018 4Runner.”
“No opinion here between the Yokohamas or Falkens (both of which I would definitely put on my Outback ) but in my experience the BFG KOs are way too much tire for the Outback . I put a set of 4 on my 2013 Outback and quickly discovered that other than looking great, and being virtually bulletproof, everything else about them is a downside. Rough ride, lot of road noise, lost about 2 mpg in fuel cost, and very heavy when I did my tire rotations, which BFG says you should do every 3,000 miles to prevent excess wear. Like they say about many things, the two happiest days in my 2013 Outback ’s life were the day I put the KO2s on, and the day, after about 10,000 miles, I replaced them with “regular” tires . Great tires for a heavier vehicle, but too much for the relatively light Outback . I’ve read many Outback owner’s reviews being very happy with the Wildpeaks AND Geolanders. Sounds like that person has an agenda.”
“I changed my mind on what tire I'm getting. I bought the BFGoodrich All-Terrain KO2 LT in an E1 load rating . Discount tire put my truck specs in and even had new tire placard for the door jam. The new pressure to meet the truck weight and GVWR axle requirements has a recommended tire pressure of 41 psi in the rear and 41 psi in the front. The Goodyear wrangler Adventure with Kevlar C1 load rated LT tires required 45 psi in the rear and 45 psi in the front tires. This due to it's lower rating. Sales manager told me the Goodrich AT KO2 have better on road characteristics, better off road characteristics, and better snow performance. The BFGoodrich AT KO2 were my first choice but didn't think an E1 Load tire would work on my rims. They were the same price as the Goodyear Adventure with Kevlar so I came out good.”

Community sentiment regarding the Cooper Discoverer AT3 LT is mixed with a positive lean. Drivers appreciate its wet and snow traction, low noise, and strong tread life under heavy loads, though some report irregular wear and persistent balancing or vibration issues after accumulating mileage.
“I have the Cooper Discoverer AT3 LT tires on my 2010 Tundra with Hawk. They are E series tires. Found this link that discusses the differences between the LT and XLT. Really like my LT's. The increased tire mileage would probably be a good thing of the price difference isn't too great. Paul”
“I got 80k (rotating every 10k) out of Coopers on my 2010 and have 40k on current 2019 SL ... Discoverer AT3 LT ... they are designed for heavier trucks... excellent noise, excellent in water. I got stuck in a grass field in the factory HT hancocks... same field few years later with coopers.. no issues.. never tried in snow but imagine they would do well...”
“From the Cooper site: Discoverer A/T3 55,000 Mile Treadwear Protection - Light Truck sizes 60,000 Mile Treadwear Protection - SUV sizes The Discoverer A/T3™ is an all-season, all-terrain tire designed to perform well on the highway and off for drivers of SUVs and light duty trucks. Excellent highway performance Excellent wet traction Improved treadwear and traction in rocky and gravel terrain M+S Rated Discoverer AT3 LT 60,000 Mile Treadwear Protection - LT-metric sizes The Discoverer AT3 LT™ with Durable Tread Technology™ hauls heavy loads with less wear and are built to withstand ongoing assault from dirt and gravel. Designed to prevent shredding on rocky and gravel terrain Extreme durability for hauling Superior control and braking in wet weather Cutting through the marketing-speak, it sounds like the A/T3 is more road biased and the AT3 LT is perhaps heavier duty and more offroad biased. And the AT3 LT is not rated for winter conditions. I've had Discount Tire try to feed me a load of BS on more than one occasion. It sounds like that's what they were doing to you. The A/T3 is definitely still available.”

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.
