I've had Cooper Discoverer AT3 4S tires on my 2019 Tacoma TRD Sport 4x4 since 2020, specifically because they weren't as aggressive and were severe snow rated. The Coopers did pretty good with this but they've been discontinued so I'm debating getting their replacement or switching to someone else.
Having said that I had AT3 4s tires on my F150, and even at 70k km they still outperformed all season tires.
Slippery situations involving rain and snow have fully convinced me of their grip. Get them. I have 22s and still bulldoze through most. Wet, muddy hills though? No problem. Cooper Discoverer AT3 4S 285/50/22 is specifically what I have. Very quiet.
I just got them for my Accord last week. So far they have been a good buy. They are far quieter and feel grippier on wet pavement than the Goodyear Eagle LS-2s that they replaced. I'll ll have to see how they wear, and feel how their performance changes over time.
Put a set on my 2017 Ford Explorer Limited up sized slightly 255/55/20 . Had for 2 weeks and have been very pleased with the performance. We have had heavy rain, Snow and ice and they have been very predictable.
I’d recommend Cooper Discoverer STT Pro, they handle well as daily driver offroad tires, road noise is not that bad on the highway and their mud and snow performance is very good.
i have the cooper rugged trek and they’re awesome! they more aggressive but still quiet on the road.
I normally rock cooper's on my cars before but this is my first ev so I'm learning as I go.
I bought coopers about 3 years ago for my Silverado 1500. I will be honest this isn't an apples to apples comparison, I bought 4 ply (first mistake) AT3 4s's. They are cracking between the tread blocks on all 4 tires. Cooper won't warranty them saying it's just cosmetic, but they are deep cracks that go all the way around the tires between tread blocks on the inside and outside. I don't use chemicals or tire shine, and they are always kept at the appropriate pressures. They also lose chunks of tread every time i take them on the gravel roads in the mountains. I'm not happy with them at all, so my recommendation is to go with the K03's.
They look to be mounted correctly; however, I find cheap chinese tires like those don't perform as well as good quality tires, are more noisy, and wear out faster.
