Expert Verdict
The Discoverer AT3 4S is a good match for drivers seeking a durable all-terrain tire with a solid treadlife warranty and winter capability. However, its wet grip performance and road noise may deter those who prioritize on-road comfort and safety in wet conditions.
Pros
Strong treadlife with an 8.5 score and a 65,000-mile warranty, which is solid for an all-terrain tire.
3PMSF rating indicates better-than-average winter performance for an all-terrain tire, adding versatility for year-round use.
UTQG treadwear rating of 620 suggests durability, especially compared to some off-road-focused competitors.
Cons
The wet grip performance is subpar for those frequently driving in rainy conditions, which could be a safety concern.
Noise level is relatively high with a score of 5, which could be noticeable on long highway drives.
Wet grip score of 6 is on the lower side, which might affect performance in rainy conditions compared to the BFGoodrich All Terrain T/A KO3.
Comfort score of 6 suggests a firmer ride, which may not be ideal for those prioritizing on-road comfort.
