2026 Tire Rack All Terrain Tire Snow Test P9 of 30
The Cooper Discoverer Road+Trail AT, a 3PMSF on-road all-terrain, shared ninth place on the snow rating but had one of the stronger sets of measured results, particularly on ice. It is a sound winter choice that the subjective ranking undersells.

“Very quiet, superb in wet conditions, seemed to wear quickly at first but that might have been from too low of tire pressure. Many rough road excursions even at end of life and it's got great traction.”

First, these tires replaced the Cooper AT3s that were on the market right before the AT3 4S replaced them. I'll talk a little about those tires. The original tires were trash in 2wd. The first time driving them home in the dry and the truck moved left and right on it's own and needed constant correction until the AT tires broke in on the side lugs (wore down enough). Then it was straight shooting. In the snow I had to use 4wd or I'd be SOL. That said I did have a time when snow dumped on me while driving and I needed to stop on a hill and get going again in 2wd and it did it with a light pedal input - though I didn't feel confident in it. If I tried stopping in 2wd in the snow I would slide like crazy and blow into an intersection. Getting going in 2wd was terrible. Sometimes I'd need 4wd just to get out of a turn lane and then I'm stuck in 4wd on the clean hwy. If I had it in 4wd, then I was golden in these old tires. Drove 50-60 in the snow and it was a bull tearing through anything I had in front of it. In the wet they were great - drove 70 tailing a semi as we flew by everyone else going 50 in a huge rainstorm.
Now to these tires. Amazing, period! Right out the gate they were true and centered - no corrections needed. They felt very much like the Crossclimate2s I have on another vehicle in the wet/dry. In the rain they feel confident. They basically improved all aspects of the generation that I had prior to these (I think it's My Original AT3s - The 4S - Then these Road and Trails). Finally have been able to take them into snow. Wow. I drove a distance of 70 miles in about an inch to 2 inch of snow where one lane was covered and one was decently open in 2wd. I never would have tried that in this truck before. I had a car trying to pass me in the snow-covered lane and they were spinning their wheels. I hit it down from 60 to 65 to get away from them and then slowed back to 60. They had to pull in behind me again. And I was just sitting there in 2wd with no issues getting going. If the snow had been heavy I would for sure get it in 4wd, but I'm really impressed for it not being a snow tire. Getting going in 2wd with a snow-covered road is no problem and stopping on one going 35 feels like I'm just on dry pavement and I hit the brakes hard to test this. I've never felt that before in a truck like this. I'm really waiting on a snowstorm to test the 4wd better, but if they're this good in 2wd then 4wd will be crazy good. The biggest issue for a vehicle like mine that doesn't have auto-4wd is that you have to decide when 2wd is safe/you won't get stuck in uncleared turn lanes. These tires have fixed that problem for me and I can run them in the summer, which I need to here and there.

Wet Traction - 9.5/10
Really confidence-inspiring wet grip. This is always a question mark with AT tires, but absolutely no trouble at all with these. Braking is especially impressive, even in standing water.
Dry Traction - 8/10
Nothing to complain about here - stopping distance and dry traction are both more than adequate for an all-terrain tire.
Snow Traction - 9/10
Really impressive snow traction. I tested in deep snow and a variety of slushy conditions. The RAV4 had no trouble at all going through 4-6 inches of snow (on grass), even even starting up a hill in those conditions provided no trouble at all. Braking is also impressive in the snow, inspiring confidence on my snow-covered driveway.
Comfort/Noise 8/10
They definitely are a little bit stiffer going over bumps than the standard all-season tires that were on the vehicle before, but nothing I would consider to be viscerally unpleasant. Noise is relatively silent, with the addition of maybe a very slight hum at highway speeds.
Overall, I have absolutely no regrets with my purchase, and I wouldn't hesitate to recommend these for a person who is interested in a fairly rugged tire that can handle all conditions adequately.
