About the Sumitomo Encounter AT2

All-Terrain Confidence, Mile After Mile

Best forLight truck, SUV, and crossover drivers who regularly mix highway commuting with off-road or winter driving and want a single tire that handles both without sacrificing ride comfort.

The Sumitomo Encounter AT2 is a second-generation all-terrain tire engineered for light trucks, SUVs, and crossovers that need to perform both on pavement and off it. Carrying a Three-Peak Mountain Snowflake certification, it handles year-round conditions including severe snow while delivering a notably composed, quiet ride on the highway. A 65,000-mile tread warranty backs the long-term value.

The Encounter AT2 uses a symmetrical four-rib tread layout built around a continuous center rib for stable, responsive steering. Deep circumferential channels evacuate water quickly to reduce hydroplaning risk, while zigzag sipes and interlocking 3D tread blocks multiply biting edges on wet, snowy, or icy surfaces. The tread compound is formulated for even wear and extended mileage, supporting the tire's 65,000-mile warranty and its 3PMSF severe-snow certification.

Questions about this tire

What does LT315/70R17 121S mean?

315 is the tread width in millimeters, 70 means the sidewall is 70% of that width, and R17 is the 17-inch rim it mounts on. 121 is the load index (3,197 lbs per tire), and S is the speed rating (up to 112 mph).

What does the 'AT2' designation mean?

AT2 stands for All-Terrain, second generation — indicating this is Sumitomo's updated iteration of the Encounter all-terrain line. The revision brings refinements to tread design and compound over its predecessor.

Is the Encounter AT2 genuinely capable in winter conditions?

Yes. The tire carries the Three-Peak Mountain Snowflake certification, which means it has passed standardized testing for severe-snow traction — a step beyond a standard all-season rating. That said, if you face sustained extreme ice or deep-snow conditions regularly, a dedicated winter tire will still offer a higher level of cold-weather performance.

How loud is the Encounter AT2 on the highway?

Sumitomo engineered the tread pattern with noise reduction in mind, and most drivers find the Encounter AT2 quieter than typical all-terrain tires. It won't be as hushed as a highway or touring tire, but the computer-optimized tread design keeps road noise at a manageable level for daily driving.

Where are Encounter AT2 tires manufactured?

Sumitomo Rubber Industries produces the Encounter AT2 at facilities in Japan, Thailand, and the United States, and manufacturing may also occur at other SRI plants worldwide. The specific production location can vary by size.

What vehicles and rim sizes does the Encounter AT2 fit?

The tire is designed for light trucks, SUVs, and crossovers and is available in 52 sizes covering 16- to 22-inch rim diameters. This broad size range makes it compatible with a wide variety of trucks and SUV platforms.

Buying from TFS Wheels

Shipping, returns & guarantees

Authorized Dealer — 100% Brand New Wheels & Tires

TFS Wheels is an authorized dealer for every brand we carry. Every wheel and tire we ship is brand new, unused, and packaged in its original manufacturer's box. We never sell refurbished, demo, or return-stock product. All manufacturer warranties apply and our warehouse is staffed by people who only handle wheels and tires — no in-transit damage, no test-fits, no surprises.

Free Shipping (Lower 48)

Free shipping on every order — wheels, tires, and accessories — to the contiguous United States. No minimum order, no hidden fees.

Standard delivery is 4–7 business days; expedited is 1–4 business days. Orders placed before 1:00 PM ET typically ship the same day. We do not ship internationally or to PO boxes.

Fitment Guarantee

If a wheel or tire marked "Direct Fit" or "Aftermarket Fit" for your vehicle arrives and does not fit as expected, we cover both the restocking fee and return shipping. The same applies if the bolt pattern does not match — provided your vehicle information was submitted at checkout.

To qualify for the guarantee, enter your year, make, model, and submodel before placing the order.

Manufacturer's Warranty

Every wheel and tire is covered by the full manufacturer's warranty against defects in materials and workmanship. Coverage terms vary by brand — most cover structural integrity for the life of the wheel and finish for 1 to 2 years from purchase. If you ever have a warranty question, contact us first; we work directly with the manufacturer on your behalf so you don't have to.

Accessories Included with Your Order

When you submit your vehicle information at checkout, the right lug nuts and (if needed) hub-centric rings are automatically added to your cart in the correct sizes — no guessing, no separate ordering.

TPMS sensors are also available in the cart. We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed. This typically saves customers the dealer or installer's programming fees, which often run several dozen dollars per wheel.

Returns

Returns are accepted within 30 days of purchase on items in new, unused condition. A 25% restocking fee applies to general (change-of-mind) returns, and the buyer covers return shipping.

The restocking fee and return shipping are waived for incorrect items, transit damage, or fitment issues when vehicle information was provided at checkout. Single wheels, single tires, mounted items, special orders, and accessories (lug nuts, locks, hub-centric rings, TPMS sensors, installation kits) are final sale.
