Goodyear Duratrac yields superior performance on roads when it comes to winter and wet traction, and off-road, the tire stays unbeatable on muddy and sandy tracks. On the other side, the Cooper Rugged Trek does better on dry pavements, offering superior fuel economy and tread life. And on rugged terrains, it won't disappoint you at all on gravel and dirt filled terrains.
Out of both tires, the Cooper Discoverer ST Maxx gets to take the back seat when it comes to on-road performance. The tire lacks in offering ample wet and dry grip, fuel efficiency, comfort and tread life. Though it shines off-road especially on gravely and rocky terrains. The Goodyear Durtrac on the other side, is impressive on highways, especially wet ones, and it offers superior winter performance as well, thanks to its interlocking sipes. And off-road its great with softer terrains such as mud and sand, but lacks in offering similar results in climbing rocks.
So lets summarize all of what I've discussed (for the folks who are in a hurry, though it's not recommended to skip all of the above). The Dynapro AT2 is a better tire to have when it comes to directional grip, lateral traction and overall steering response. Bu that only goes for dry pavements, as on wet, the tire is below average (among it's competitors). Other than that, the tire deals off-road great on rocks and mud, and offers better tread life. On the other side, the Dueler AT Revo 3 gives out better wet traction, fuel efficiency, and sand traction. And although it's not 3pmsf rated, it's winter traction is almost on par to it's counterpart.
Goodyear Wrangler AT/S is a better tire for pavements and highways, which is no surprise, given its on-road oriented structure. Though it's still surprising to see, how it still lacks when it comes to wet grip and winter performance. Though its great on dry, fuel economy, overall comfort and tread life. Goodyear DuraTrac on the other side does great on snow grip and wet traction (its the only one with severe winter rating here). Moreover, the tire is also better by a huge margin, off-road, especially on muddy tracks.
Let me sum up things here quickly. The Atturo X/T is a great tire to have on roads, though it's wet grip can get a little better (it lacks in comparison here). And same goes for its overall winter performance too. Though the tire does better in the fuel economy section, tread life, and comfort (in terms of noise). On the other side, in case of rugged terrains, you'd be better off with Duratrac, where it's mud traction is the most impressive. And on roads, the tire's offers superior cushioning to the bumps and enhanced wet grip.
Let me summarize all of the things I've discussed above. So out of both tires, the Kenda Klever AT2 shows up with a better traction on both wet and dry environments. And the tire brings superior comfort, fuel efficiency and tread life with it as well. On the other side, the Goodyear Wrangler DuraTrac comes out on top, on rugged terrains, where it shines the most on muddy tracks. Also both tires are pretty great when it comes to winter traction.
So to sum things up, the Michelin Defender LTX MS being an all-season tire yields better results on pavements, and highways. You get to see better traction values on both wet and dry environments, and tire show superior fuel economy and tread life. Moreover, it also does a lot better when it comes to providing a comfortable ride. Michelin LTX AT2 on the other side, does better on all off-road terrains, it's voided structure allows for better mud escaping, and it's notches everywhere bring about superior grip on rocky terrains.
Michelin LTX AT2 gives you a better dry grip, and steering response, tread life, and similar noise dampening capabilities. Off-road, the tire does better on rocks and mud. On the other side, the Firestone Destination AT2 provides you with better wet traction, comfort performance, and winter traction, and off-road it outperforms its competitor on sandy terrains.
Both tires are great all rounder options, if you are looking for daily driving options. Though still out of them, the Michelin LTX AT2 comes out better off-road, as we just saw above. The tire render superior on-road comfort. And gives you with better tread life (if you compare the LT sizes especially). Moreover, it's wet traction is although nothing to be proud off, it's still better, comparatively. The Hankook Dynapro AT2 on the other side, is quieter on roads, provides superior fuel economy, winter traction, and gives much better traction on dry roads.
So in the end it all comes down to this. The Michelin LTX AT2 comes on top when it comes to dry traction on highways, fuel economy and tread life(of course relatively speaking here). And off-road the tire shines on rocks and mud, though its sand traction is on par with its competitor. Hankook Dynapro ATM on the other side yields superior winter traction, yields better comfort and shows less overall slippage on wet roads.
Let me conclude all of the things I've discussed, though it's not recommended to leave any of the above, if you are not in a hurry. The BF Goodrich is a better tire to have off-road. It yields superior traction on sand, rocks, and muddy terrains. Moreover, the tire is also very gripping when it comes to snowy terrains, though overall I'd rate both tires equal here. Other than this, fuel usage is better on BFG, along with comfort, both in terms of noise, and bumps absorption. On the flip side, the Dueler A/T Revo 3 features superior dry and wet grip on pavements, and has a better tread life in comparison, though both tires have the same 60k miles warranty.
The Grabber ATX comes out on top, when it comes to on-road grip, fuel, tread (life), and comfort departments. On the other side, the Cooper ST Maxx off-road performance really makes all-terrain tires worth it. But the tire really need some aggressive sidewall lugs.
