“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”

“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...”

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.
