General Grabber A/TX vs Cooper Discoverer Road+Trail AT tires on traction
Let’s analyze the traction performance of both tires and find out which tire is better when it comes to maintaining road grip on- and off-road, and biting the surface more efficiently.
The Grabber ATX scores an 8.5 SimpleScore rating in traction, ensuring a solid on- and off-road surefootedness with an extra power of surface-biting in snowy and icy conditions because of Three Peak Mountain Snowflake certification. The aggressive tread blocks improve the tire’s ability to bite the surface in muddy and other rugged conditions like rocks, gravel, dirt, and sand. Likewise, the sipes are optimized to offer strong surface holding ability on snow and ice. The wider gaps between the tread allow the tire to self-clean mud and other unwanted objects for an increased grip in rugged conditions.
On the contrary, the Discoverer Road+Trail AT also surprises with an 8.6 SimpleScore rating in traction, assuring a reliable on- and off-road traction and grip. Like its peer, the Road+Trail AT tire is also Three Peak Mountain Snowflake rated for reliable traction and grip in rugged conditions. There are advanced interlocking tread lugs for increased all-season traction, whereas the detailed sipes improve grip on snow and ice. The circumferential and lateral grooves facilitate quicker removal of water and dirt from the contact patch for increased traction performance, whereas the sharper tread block edges ensure confident surface-biting in off-road conditions.
While both tires are great on the traction part, it is the Discoverer Road+Trail AT that marginally exceeds in score and wins the battle here.

Commencing with the Grabber A/TX, the tire earns a respectable 8.2 SimpleScore in longevity. It also comes with an up to 60,000 mile limited manufacturer tread life warranty, which ensures that the tire will last longer. Thanks to the robust strength and durability, the tire is stronger both on the outside and inside to withstand the off-roading pressures and impacts. The credit for this goes to the patented Duragen technology. Additionally, the optimized footprint contributes to even and longer wear.
On the contrary, the Discoverer Road+Trail AT is brilliant when it comes to longevity and earns a whopping 9.8 for its extended service life. The 65,000 mile limited manufacturer warranty further assures a longer service life. The EnduraGuard Design offers strength and durability to resist cracking, tearing, and cutting.
