“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.”

Higher is better. The Relative Score follows your weights below; category scores do not change.
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.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

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 Yokohama Geolandar A/T G015 is predominantly positive, with owners highlighting its quiet highway manners, strong snow and wet traction, and good light off-road capability. Criticisms primarily center around a slight 1–2 mpg fuel economy loss, potential ride harshness or softer P-rated sidewalls depending on vehicle application, and gravel retention in the tread. Many drivers consider it a balanced all-terrain tire suited for predominantly on-road daily driving with occasional trail use.
“GEOLANDAR A/T G015 Anyone running these on 17" rims, stock or other? I have Enkei M52 rims, 17x7.5 and 45mm offset. What size fits without rubbing? 215/60R17 looks to be the closest, the only other size close is 225/65R17 which I think will be too big without a lift. I am open to other suggestions for off-road capable tires that will mainly be used on-road. K02 is out because they don't fit without rubbing, and I plan to add flaps at some point and do not want to lift the vehicle or get different rims.”
“I have Yokohama Geolandar A/T G015 on my explorer and they have been great on the highway, towing, off road. 2 summer seasons so far and they still look nearly new. I use winter tires so far in winter tho... My other vehicle (AWD Delica minivan) has chinese brand RoadX RXquest AT QX12 and they have been amazingly quiet on highway - have not used in winter or highway but i will be using them this winter as they are rated 3 snowpeak so qualify as winter tires for my insurance...no issues with handling or wet performance noted so far. only had them on a few months so cannot comment on tread wear.”

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...”

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.
