The Encounter AT is Sumitomo's Off-Road All-Terrain tire developed for drivers of pickup trucks, crossovers and SUVs who want go-anywhere capability and durability combined with confident all-season traction, even in snow.

Utilizing a rugged, all-terrain compound molded into a purposeful pattern, the Encounter AT is designed to perform on any surface. The open tread design features stepped edges on the center blocks for added bite in loose terrain, and the open shoulders employ connecting ribs for improved stability. Four wide, circumferential grooves effectively evacuate water from the contact patch for confident grip where standing water is present, and in-block sipes create the additional biting edges needed for traction on slippery surfaces. Winter-focused zigzag sipes in the shoulders and the independent tread blocks work together to provide snow traction. All tires in the Encounter AT lineup meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.

The Encounter AT's internal construction consists of a two-ply polyester casing beneath two wide steel belts. A spirally wound reinforcement adds increased support for enhanced stability and ride comfort.

Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol may provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.

...From heavy rain in the east, to snow packed roads in the Rockies, to dry conditions in the Southwest and California these tires performed very, very well...

I did a bit of research and looking through the overall reviews these seemed like the best fit for me. I had to make a trip from the east coast to the west coast in December so I planned to encounter a wide range of different conditions. From heavy rain in the east, to snow packed roads in the Rockies, to dry conditions in the Southwest and California these tires performed very, very well.
So far wear has been excellent, no cupping or other abnormal conditions. I have had them in deeper snow, 12+ inches and it took a bit of coaxing in 4wd to get moving but they dealt with the snow just fine as well as hard packed snow, slush and frozen surfaces.

I would definitely purchase these again.

Great set of tires at this price point. They handle well in dry and wet road conditions and the road noise is less than might be expected from an AT. The Severe Winter rating means that they do quite well in snow conditions as well. I had a set on my 2006 Tundra and now this set on our Tacoma and will certainly buy again when needed.

...Still break the rears loose a bit easily in rain or snow (maybe I've an unnecessarily lead foot?), but once underway, there's enough grip to inspire reasonable confidence without encouraging silly gratuitous driving (always in a bit of a rush)...

For the price (which had very recently gotten considerably better sans warning), tough to think of a better jack-of-all-trades tire.
Still break the rears loose a bit easily in rain or snow (maybe I've an unnecessarily lead foot?), but once underway,
there's enough grip to inspire reasonable confidence without encouraging silly gratuitous driving (always in a bit of a rush).
The tires communicate with noise and vibes when taxed with verve, and they lose their composure gradually when leaned on.
They do discourage ME from driving at 8/10ths or more, but they don't just give up without warning or protest.
Think 'less off-roady' tires would make it easier to be more effective at being an annoying driver.

I actually climb curbs whenever I parallel park, to leave a bit more room on slim roads that are barely 3 or 4 vehicles wide.
Sidewalls actually make this easier than expected, felt encouraged enough to go looking for excuses to 'soft-road'.
Despite recent snowfall, no need for 4WD; just a bit less leadfoot got me through dirt mud snow slush and any combo of the above.
Unpaved trails were made light work of. Haven't gone too far off the beaten paths yet, but looking forward to it now!

They're not ideal long road trip tires, but they behave and respond well enough on the highway, even well over posted speed limits.
Don't quite love them, but I'm pleasantly surprised.
Provided the price stays reasonable, and the performance doesn't degrade too much over time, I'll consider them again.

The Sumitomo Encounter AT excels in winter conditions, with most customers scoring snow and deep snow traction 9-10. Ice traction earns strong 7-10 ratings, showing reliable grip in rugged terrain. A few lower ice scores (4-6) suggest varied experiences on extreme ice.

...Tires seem to be good in the snow.

Have not put a lot of miles on these tires. I have noticed after my truck sat a few weeks, the tires developed flat spots. After driving a few miles the flat spots worked themselves out. Tires seem to be good in the snow.

...Drove 4 hours through blowing snow and slush on the highway and didn't feel them lose grip at all. There was a little squirming changing lanes through the heavy slush built up in the middle, but they seemed to cut through it pretty good for the most part. We were cruising past everyone on the 4 lanes driving at the speed limit (110) while all other traffic had slowed to around 80 km/h...

Bought these from my local dealer up here in Canada (sorry Tirerack) and immediately set out on a road trip the next day. Oh joy, it was snowing in September up here in North Saskatchewan and Alberta......no problem, perfect conditions to throw down the gauntlet and test them out. Not a lot of info on the Sumitomo Encounter AT's, but what is there rates them very highly....on to my review.

Drove 4 hours through blowing snow and slush on the highway and didn't feel them lose grip at all. There was a little squirming changing lanes through the heavy slush built up in the middle, but they seemed to cut through it pretty good for the most part.
We were cruising past everyone on the 4 lanes driving at the speed limit (110) while all other traffic had slowed to around 80 km/h. Not once did the Jeep feel anything but planted and in control......I know for a fact that the Firestones would not have handled it anywhere near as well.

Added bonus, they are as quiet or quieter on the road than the stock Destination AT's, no hum, no howl, no drone......

Weekend mileage was around 1100 kms return trip with a full gamut of weather and terrain; Snow, Slush, rain, mud (friend lives in the country, 9 miles of muddy gravel road), Off-road, Rain, and Dry pavement.

Overall, I am very happy with the purchase so far and this trip got a big passing grade from me.
Sumitomo Encounter AT gets my recommendation and is definitely a replacement tire to consider.

These tires almost instantly impressed me. Great response, great traction. Yes they do have a little more road noise than some of the others, but for 500$ cheaper for a set, I'll take the tiny tiny bit of road noise. I recommend these.

...Road noise is no different than the original OEM tires, despite having significantly greater tread...

Love these tires. The OEM tires that came with this truck only lasted 26,000 miles, despite regular rotation and inflation. We tow a 13,000+ 5th Wheel RV and have had nothing but great experience on local roads and Highways (based on 4,000+ miles to date). Can't comment on off-road (other than campgrounds), or snow (Georgia). Road noise is no different. than the original OEM tires, despite having significantly greater tread. We continue to rotate these every 3-5,000 miles and see no indications of uneven wear, sidewall cracking, etc.
