What Hankook says about the Dynapro AT-M

Hankook calls the Dynapro AT-M “the best on/off road tire for 4X4 vehicles.” The company says the “Dynapro AT-M employs a tough pattern design and block structure to overcome any road.”

The tire offers puncture resistance with a wraparound tread that gives the tire a rugged look. The tire also has a reinforced under-tread gauge that helps prevent internal damage from impacts that occur during off-road use. Hankook covers it with a 50,000 mile treadwear warranty.

Uniform government and independent testing results

All P-metric Dynapro tires having Uniform Tire Quality Grading scores of 560 for treadwear. Letter grades of “A” and “B”, respectively, were assigned for traction and temperature resistance. Consumer Reports gave it a score of 58 out of 66.

Dynapro received mostly above average marks in testing

Although independent results were mixed, the Dynapro received no grade below “good” from Consumer Reports. It received grades of “excellent” in both tread life and dry braking. Grades of “very good” were achieved in hydroplaning and snow traction testing.

However, the wide tread that is at the root of these grades contributed to the tire receiving a grade of only “good” in noise testing. The tire was awarded the grade of “good” in six testing categories: wet braking, rolling resistance, noise, ride comfort, handling, and wet braking.
