Dunlop Grandtrek AT20 Problems
While the Dunlop Grandtrek AT20 is a capable tire, some drivers have reported a few issues that might affect their overall experience. These include a bit more road noise, challenges in light snow, ice, or slush, and shorter tread life than touring alternatives. It’s good to know that many of these problems are from isolated reports or can be helped with proper maintenance like keeping the right air pressure, regular rotations, and proper alignment.
Understanding these concerns can help you decide if this tire is the right choice for your driving needs.
Road Noise
Typical
While many say the tire is quiet for its design, a few drivers have reported that it makes more road noise than factory tires or some premium options. This can be especially noticeable on paved roads.
Light Snow, Ice, and Slush Performance
Typical
The tire performs very well in deep snow, but some drivers have found that it does not grip as well in light snow, slush, or on icy roads. This can sometimes lead to slipping or less stable cornering in those conditions.
Tread Life Expectations
Typical
Performance-oriented tires like the Grandtrek AT20 typically wear faster than touring tires due to their softer, grippier compounds. This is a normal trade-off for enhanced grip and handling. Regular rotation and proper inflation help maximize tread life.
Balancing and Installation Issues
Typical
A few reports mention problems during mounting or balancing the tire. Some drivers experienced vibrations or a wobbling feeling when the tires were new, which might require extra adjustments to get a smooth ride.
The Bottomline
While the Dunlop Grandtrek AT20 is a strong tire overall, it is not without its concerns. Issues such as higher road noise, reduced traction in light snow, ice, or slush, shorter tread life have been noted by some drivers.
