Two scoring systems, side by side

Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.

How scores work

Relative score: 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
Road tests: 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
Owner reviews: 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.

Themes extracted from 688 owner reviews found online.

The Cooper Discoverer A/T3 4S receives overwhelmingly positive feedback from users for its exceptional balance of on-road comfort, low road noise, and reliable all-weather traction. Drivers frequently praise its performance in heavy rain, deep snow, and light off-road conditions, noting that it punches well above its price point compared to competing all-terrain tires.

Pros

Exceptionally quiet and smooth on-road ride compared to typical all-terrain tires
Superb traction in wet, rainy, and deep winter snow conditions
Strong value and competitive pricing relative to performance and lifespan
Aggressive yet refined aesthetic appeal that enhances the look of trucks and SUVs

Cons

Potential for accelerated tread wear under heavy off-road use or demanding mountain driving
Occasional reports of balancing issues or out-of-round tires requiring multiple adjustments
Minor fuel economy drop or increased rolling resistance when switching from standard highway tires

Worth knowing

Users note that choosing the correct load range is critical, as P-rated or SL options deliver a much smoother, compliant ride on light trucks and SUVs compared to stiffer E-rated LT tires.
Mid-sized trucks and smaller SUVs (such as Subaru Foresters, Toyota Tacomas, and Jeep Wranglers) particularly benefit from the tire's balance of beefy aesthetics and civilized highway manners.

“I went with Cooper Discoverer AT3 4S for the Touareg and couldn't be happier. Made in the USA to boot!”

“Cooper Discoverer AT3 4S discontinued, good alternative? I was hoping to replace my stock tires with the Discoverer AT3 tires since I hear really good things about them and they are a bit more aggressive. Seems like they are discontinued at all the normal tire shops online. So what are my alternatives for an AT style tire? Looking for 235/60R17 to put on Drag DR-31 rims. I live in CO so snow and some light off roading are things to consider. Read more”

“Installed new Cooper Discoverer AT3 4s tires on my 1500 today. Took off a set that I put on three years ago when the stock tires wore out. I think I got good performance from the first set, but they didn't last as long as I would have hoped. They were getting pretty close to the wear bars, so had some life left. The guy at the tire shop estimated that I would get another 10000 miles out of them. They had a little less than 40 K miles. We got a bit of snow here this week, and I could tell that they were not gripping nearly as well as they did before. If it was spring/summer, they would have stayed on the truck. I will be driving to Maine next week, pulling a snowmobile trailer, so I decided that it was time to buy now, rather than risking a wreck. New tires look similar to the old ones. Still made in USA (good), no longer available with white letters, black wall only, in cast that is important to you.”

“I went with the Cooper Discoverer AT3 4s (275/65/18). The Michelin Primacy XC were on there when I purchased and they were terrible. I like the looks of the Coopers...the ride is much more controlled and a bit softer over broken surfaces. They do have some slip off the line of you give it full throttle real similar to the XCs. I was looking for an AT that would be great at hooking up in dry weather but probably not gong to find an AT that is sticky enough. They're brand-new so I'll give an update after a few hundred miles or so (I don't put a lot of miles so it'll take time). Thanks to the Forum for the info!”
