Scouter Analysis

The Sumitomo Encounter AT is a solid choice for those who need a durable all-terrain tire with a strong emphasis on longevity. With a treadwear warranty of 60,000 miles, it surpasses the category average, making it a cost-effective option for long-distance adventurers. The tire's wet grip score of 6.0 is above average for the segment, providing confidence in rainy conditions. For all-terrain tires, off-road traction and durability are key, and the Encounter AT's 3PMSF certification suggests it can handle light snow better than many competitors. However, its dry grip is slightly below average, which might be a consideration for those driving frequently on dry pavement. Noise and comfort levels are average, which is typical for an all-terrain tire but worth noting if on-road refinement is a priority. When compared to competitors like the Pirelli Scorpion Zero All Season, the Encounter AT offers better treadlife but sacrifices some on-road comfort and noise levels. The Yokohama Geolandar A/T G015 might offer a more balanced performance across all terrains. If quietness and ride comfort are your top priorities, you might consider the Pirelli Scorpion Zero All Season instead.

Pros

Treadlife rating of 8.8 with a 60,000-mile warranty exceeds the all-terrain category average of 55,717 miles.

Wet grip score of 6.0 is above the category average of 5.2, which helps in maintaining traction on wet roads.

The 3PMSF certification indicates better snow performance than non-certified all-terrain tires.

Cons

If you prioritize a quiet and comfortable ride, consider alternatives like the Pirelli Scorpion Zero All Season.

Dry grip score of 6.5 falls slightly below the category average of 6.6, which may affect performance on dry pavement.

Noise level is average at best, with a score of 5, which matches the category benchmark but doesn't stand out.

The Pirelli Scorpion Zero All Season offers a more refined on-road experience with higher comfort ratings.
