“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...”

“2019 zr2 Duratracs were a good tire. Only complaint was the last 10k of their life they got LOUD on the pavement. Good in snow, good on trails. Went to KO2s when it was time for new shoes. Like the stronger side walls and rating, better traction in hard dirt, no real difference in loose rocks or winter to me. Definitely harsher ride w the stiffer sidewalls. I have the ZR2 now as a 2nd rig (finally) so it doesn’t get daily miles. I’d purchase the KO2s again. Daily driver? Duratracs are better, but that horrid drone the last 10k of life would be enough for me to pass on them. 🍻”

“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.”

“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”

“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.”

Tire B

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.

“I drove to the Deadhorse, Alaska (as far north as you can drive in America). The Dalton highway is a notorious 400 mile gravel road start just north of Fairbanks. Lots of people bring 2 spares. I had 0 flats. KO2 eat snow and sand for breakfast. They definitely improve my Q5 and allow me to hang with proper off-roaders (at least for a little while)”

“Yes, totally fine to run them on the stock 5.5" wide wheels, no rubbing and they're a good option for an upgrade while minimising drawbacks. I ran exactly that size KO2 for ~50,000 km, ended up selling them onto someone else and swapped to different wheels and tyres just for something different.”

“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.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
