Sumitomo Encounter AT Review & Buying Guide

Sumimoto’s Encounter AT is a tire that offers excellent value and a competitive performance despite being an entry-level tire. When it is time to go for an adventure, you need a tire that can withstand any surface and capable of whatever you request from it.

For most all-terrain tires, you will get large, aggressive tread blocks with a good grip on loose grounds such as sand and mud. Still, it has a soft compound that ensures good wet traction and less noise on dry roads.

Sumitomo is a company based in Japan, and it is a tire company that has been around for a long time, up to 100 years. The quality tires they produce have been a significant player in the tire industry for many decades.

The Encounter AT is a tire built to offer the level of traction that off-road and casual devotees need. Its tread patterns are large and are made from a specialized compound. The large groves in the middle of the tire ensure that channel water doesn’t get underneath the tire and helps reduce the risk of hydroplaning.

The Sumitomo Encounter AT tire has biting edges that help on slippery surfaces through the lateral grooves and 3D sipes so it can go anywhere and do anything in your vehicle. The sidewall tread helps keep the rocks and stones from getting caught up between the treads.

How well does Sumitomo Encounter AT perform?

The Encounter AT slightly differs from off-roading and pure-mud tires. It is a tire that focuses on performing across all terrains. It has got a good tread pattern that is not as harsh or as deep as that of the pure mudding tires. And this helps to reduce noise that is generated when moving on the highways.

The Encounter AT has found a way to balance everyday driving with off-road capabilities, and it offers good value in this regard. It has deep tread grooves that are molded into an asymmetrical tread pattern – this helps it fight against wear and provide an improved and comfortable ride.

The tire has four large groves across the circumference. This creates deep channels between the large tread blocks and ensures adequate water drainage from the tire’s bottom. The lateral grooving present also means water is forced out through the sides while the tire rubbers move on hard surfaces. The effects of hydroplaning can be reduced when the rubber contact stays on hard surfaces, as the tire keeps grip.

Three tread strips form the inner blocking, resulting in a continuous, wide footprint being created on the road. The pattern designs help reduce noise from the tires when on hard surfaces and offer more grip when on loose surfaces such as sand, gravel, or mud.

Let's talk about durability

The small, zig-zag grooves offer extra flexibility to the tread. They pinch into loose terrains like sand, snow, or mud, acting as different grab points for treads; this allows for better traction when moving on off-road surfaces or some softer surfaces. The tread in the Encounter AT does well in snowy conditions, even though it is not a winter tire. It fulfils the requirements for the three-peak mountain snowflake symbol. It offers decent snow traction and does well in cold weather. Stones and rocks are kept from getting stuck by the shaped treads along the shoulder of the tire.

Internally, there are the steel belts wrapped in nylon, which reinforces the tire structure. In a less ideal terrain, the strengthened tires will maintain shape, transferring vehicle weight. The rigid side walls also boost ride quality, especially when the tire has to resist heavy loading.

How is their tire warranty?

Sumitomo offers one of the best warranties in the tire business. For the Encounter AT, there is a 60,000 mile or four-year tread warranty. You are guaranteed tire uniformity for the initial 2/32 inch of wear.

You will also get a warranty on the manufacturer’s defect for six years from the manufacturing date or five years from the purchase date. You are covered for the first 2/32 inch of the fault, and you can get a replacement until 2/32 inch remaining. You will also get a one-year warranty or initial 2/32 inch wear for a road hazard.

There is a 2-year roadside plan with the Encounter AT, and a 30-day test drive guarantees after the purchase.
