If you’re ready to learn more about the Dunlop Grandtrek AT20s and whether these tires are for you, let’s dive in.


The Dunlop Grandtrek AT20 is a tire designed to fit SUVs, 4x4s, and sports vehicles. It is an All-Terrain and All-Season tire, used for vehicles traveling on highways. This tire is designed for a luxurious ride that promises no noise, and excellent traction on any terrain.

The tire’s features include a new Multi-Pitch Tread Design to eliminate on-road noise, a circumferential groove design, and cross-cut snipes to push away water for wet traction. This tire is classed as an all-terrain tire but is not suitable for off-roading. Compared with 45 other all-season tires, the Dunlop Grandtrek AT20 ranks 41st.


Many ratings and tests show good traction in dry conditions, but poorer traction in rainy and snowy conditions.


The Dunlop Grandtrek AT20s are tires designed to have excellent traction, due to their circumferential grooves. However, the reviews are mostly negative.

Multiple individual tests report one-star ratings for wet traction. Other reviews from customers report no grip from the tires in both wet and snowy conditions.

Although the tires hold a fair rating of 5 for wet traction and hydroplaning resistance, users comment on the low to no grip of the tires and the increased hydroplaning. Tests resulted in users reporting the slippery and sliding of tires during wet conditions.


Most users report satisfaction with the performance of the Dunlop Grandtrek AT20s in dry road conditions. The tire holds a 6.2 rating out of 10 for dry performance, with dry traction and steering response having above a 6 rating.

For off-road conditions, ratings suggest a good performance, but reviews from users suggest poor experiences driving on rocky or muddy terrain.


Although the tires are designed for all types of terrain and seasons, users have said that the tires are borderline “dangerous” in light snow and ice. One user specifically replaced the tires at 3,000 due to having “no traction on snow or ice”.

Users seem to have a negative rating of this tire in snowy conditions. Consumer surveys report a 3.8 out of 10 for snow/winter performance. Many of the reviews are not fond of the tire’s performance in winter conditions.


Most reviews show that users are comfortable with the way the tires look and feel while driving, except in rain or snow.

The ride quality has a 6.8 rating out of 10, with reviews to back it up. Other reviews report a 66% rating for handling and a 6.1 rating for steering response.

The Dunlop Grandtrek AT20 has a high rating overall for steering and cornering, with a few lower reviews that report rough turns. Overall, the feel of the tires is satisfactory for most users.

Noise and Comfort

The VersaLoad Technology and tread design are supposedly used to enhance ride comfort.

Users report that one of the best things about this tire is the quiet ride. In customer reviews, the ratings for the level of noise were around 7 out of 10, with one user reporting the drive was like riding on marshmallows.

Individual tests of users report a high rating on the noise generation of the Dunlop Grantrek AT20 tire. Most reviews are steady when it comes to both the noise and comfort level.


The Dunlop Grantrek AT20 tires have a warranty for tread life, uniformity, and materials. The tread life warranty covers the replacement of a tire up until 6 years have passed or until the driver reaches 60,000 miles.

A uniformity warranty provides replacement in the first 1/32” to 2/32” or first year of service of a manufacturer-inspected tire if it disrupts the rest of the vehicle.

The workmanship and materials warranty allows a tire to be replaced if the manufacturer is at fault for materials or quality of workmanship. For the first year, you can get a free tire if it is a warranty-covered reason.

One of the best aspects of this tire is its long-lasting quality. Amongst low reviews of wet and snow traction, the ratings for durability are high, reaching 5/5 starts. Many users report that their tires lasted long past their warranty.


Compared to other tires, the Dunlop Grandtrek AT20s are of the more affordable kind. Prices range from $100 to $300.

Other tires that have higher ratings for traction and tread wear are close to the same price, so the performance of these tires may not be as high as other tires that are close to the price of Dunlop Grandtrek AT20s.

Although, most users report long-lasting treadwear for these tires, even after 30,000 miles.


The Dunlop Grandtrek AT20 tires have user reviews that are mixed and inconsistent. According to some reviews, the overall rating for recommending these tires is very low; only 2.8 out of 10. 

In a side-by-side comparison, a BFGoodrich All-Terrain T/A KO2 showed a higher rating in all categories of the BFGoodrich All-Terrain T/A tires compared with the Dunlop Grandtrek AT20.

We recommend that other tires such as the BF Goodrich All-Terrain, the Michelin Defender LTX, and the Goodyear Assurance WeatherReady are more efficient in all seasons and traction for all terrain types.


From the data collected through reviews and tests, we can conclude that the Dunlop Grandtrek AT20 is highly effective in ride comfort, noise reduction, and tread life, but performs poorly in wet and winter conditions.

Overall, most consumers are happy with the tread life and durability but unsatisfied by the wet and snow performance of the tires. There are mixed reviews about durability and dry and off-road traction. Most ratings lean toward the positive side for dry traction but are not as great for off-road traction.

Based on our research, we recommend this tire only for vehicles in dry seasons and not for anyone who frequently drives in rain or snow. Other tire models such as the Michelin Defender TRX are better for off-roading and all-season traction.
