The Dynapro AT-M (RF10) is Hankook’s premium On-/Off-Road All-Terrain Light Truck tire developed for light trucks, vans and sport utility vehicles. Introduced as Original Equipment on 2015 model year Ford F-150 pickups, Dynapro AT-M tires are now available in a range of sizes that offer Hankook’s best all-terrain grip and acceleration both on- and off-road.

Hankook Dynapro AT-MHankook’s specialty light truck compound is molded into a wide, independent block, symmetric tread design with an enlarged footprint to enhance grip and acceleration while resisting uneven wear. A wraparound tread design gives a rugged look, increases traction in muddy and snowy conditions and helps guard against cuts and bruises. Stone ejectors in the center and shoulder grooves help prevent tire damage from stone drilling or external impacts while tiered side grooves and scallop grooves between the tread blocks increase the number of biting edge to enhance off-road and wintertime traction.

The tire’s internal structure features two high-strength steel belts reinforced with a spirally wrapped nylon cap ply to combine strength and ride quality. A polyester casing promotes ride quality and rim flange protectors help guard expensive wheels from accidental curb damage.

Note: While most Hankook Dynapro AT-M (RF10) tires meet the industry’s severe snow service requirements (and are branded with the three-peak mountain snowflake (3PMSF) symbol), selected tires do not. Specific tires/sizes not meeting the industry’s severe snow service requirements are identified with a “Not Rated For Severe Snow” notation on Specs.

Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol 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.


  1. have loved these tires. 65000 miles and they still look great. quiet on road. had bridgestone duellers previously and these have lasted much better.

  2. Worst tires I have ever owned or perhaps I am spoiled with better tires. No traction in the snow whether it’s 1 inch or 10. (Lots of tread left) They even slip in the rain to the point I no longer trust them. I will never buy Hankook again.

  3. Replaced stock 20″ highway tire with these. New tires are a little loader as to be expected with an all terrain tires. These tires blow my Bridgestones out of the water though. 2WD all the way to work in snow compared to needing 4WD. My only complaint was a small drop in MPG but the loss is totally worth what you gain in performance.

  4. As the OEM tires they are just ok in my opinion. I live in the Sierra Nevada mountain range and have driven off road up very steep mountains and various terrain you get while off road. The tires do good enough but never great. I aired down a few times while going up to a hunting spot with rocks and loose sand and had pretty bad tire damage to my side wall and tread. This happened at about 5k so I just replaced the tire costing about $300 total. Then I was out on a dried lake bed with lots of rocks and light mud and got stuck. I tried all the tricks but needed a pull to get out of that mess. I know the tires are not really meant for that type of Terrain but the other ford that pulled me out had Toyo all terrain on and got into the same spot and out without issues. Snow was great at first but on my 2nd and 3rd winter in Tahoe they handled ok I had to keep weight in the back and air down a little bit to keep traction. I didn’t really have to do this but anytime I was at speed or taking a corner it always would feel like the rear would kick out more then it should for 20 mph in 4-High and I was just trying to get more traction so it wouldn’t happen when a car was coming around the corner. I did do light offroad during winter and it handled some steep stuff that was both well driven on and fresh 8 inches of snow. I wouldn’t say I felt super confident on the compacted stuff but the fresh powder was fine. I’ve only done very light trailer towing with the tires and they handle it just fine like they should the trailer weight was 2600lbs. Highway is just fine and not noisy. Overall I would say the tires are okay not to great at anything. I feel the price is a bit much for the tires. I know a set of Toyo, Nitto, Bfgoodrich, so on gets you a better all terrain or even a hybrid tire.

  5. Ive got close too 40,000 miles on these tires and I’ve still got about 30-40% tread left. I am very satisfied with their performance and overall quality. The only issue I’ve had is that for some reason or the other I have picked up lots of stuff in these tires. I am not sure if its just been my luck or the tread pattern of this tire, but over the past 3 years I have had to plug every single one of my tires. One time I got a flat in during a 2 foot snow storm. That was not a fun tire change. From nails to random debris they’ll grab it. This is my only concern with purchasing these tires again.
