The AT3 4S is designed for on- and off-road use, but some users find it doesn’t perform as well as other tires in mud or sand. It’s also a bit noisy on the highway.
Performance on Wet Roads

Off-road Performance

The Scrabble Grip Technology is a special tread compound that is molded into the tire’s tread blocks. This compound helps to improve traction by providing a more uniform contact patch with the ground.
Performance in the Snow

Comfort and Noise
While the AT3 4S is a solid performer in most conditions, it does have some drawbacks. One is that it’s not designed for serious off-roading. If you plan to do any severe mud or rock crawling, you’ll want to look at a dedicated off-road tire.
Another potential downside is that the AT3 4S is a bit noisy on the highway. This is common with all-terrain tires, but it’s something to keep in mind if you’re looking for a quiet ride.
