Yokohama and Cooper are two iconic tire brands that evolved around the same time. While Yokohama was established in 1917 in Tokyo, Japan, Cooper was formed in 1914 in Findlay, OH. Yokohama’s range of tires is applauded for their design and technology, and the tires are made for use on passenger cars, high-performance vehicles, light trucks, CUVs, SUVs, commercial vehicles, and off-road vehicles. On the other hand, Cooper has earned a high reputation because of its quality tires and focuses on offering the best driving experience to its customers. Cooper’s tire range caters to passenger cars, light trucks, CUVs, SUVs, and commercial vehicles.
The same can be expected from the Geolandar and Discoverer all-terrain tires offered by these manufacturers. These tires are engineered to deliver reliable on- and off-road performance and are suitable for use on light trucks, SUVs, and commercial vans. But, which out of these two tires should you consider for purchase? To understand this, we have compared the Yokohama Geolandar A/T XD vs Cooper Discoverer S/T Maxx tires utilizing SimpleScore. This will give you a transparent analysis of which tire you should consider based on your driving preferences and needs.

Yokohama Geolandar A/T XD vs Cooper Discoverer S/T Maxx tires on traction
All-terrain tires are used for on- and off-road driving, and therefore, it becomes essential that these are adequately equipped with features and capable of offering better traction performance. Typically, these tires are offered with an all-season tread compound, which allows them to perform in dry, wet, and winter weather conditions. Both Yokohama and Cooper have put in efforts to ensure that the traction performance of their tires isn’t compromised. But, in reality, how are they, and what SimpleScores do they boast? Let’s check it out!
The Yokohama Geolandar A/T XD boasts a great 8.3 out of 10 SimpleScore in traction and features an aggressive tread design that has multiple wavy sipes combined with an optimized void-to-lug ratio that ensures better traction performance on- and off-road, year-round. It is Three Peak Mountain Snowflake certified, which means it can offer improved traction and grip in moderate to severe winter weather conditions on snow and ice. This Geolandar tire can also be pinned with #15 studs (wherever permissible) to provide increased winter traction on snowy and icy surfaces. Additionally, the shoulder and center blocks of this tire feature sharper edges for increased traction performance, whereas the wider grooves force water out from the footprint for improved traction performance in wet and winter conditions.
Contrarily, the Cooper Discoverer S/T Maxx sports an admirable 8.6 out of 10 SimpleScore rating in the traction area. Overall design and tread compound of this Cooper all-terrain tire are optimized for increased traction performance. The deeper tread and wider footprint allow the tire to maintain surefootedness in off-road conditions, while the sipes on the tread, and even the sharper edges of shoulder and center blocks allow the tire to firmly grip the surface and improve traction performance. The tread grooves keep the footprint clean by evacuating water, slush, and snow for improved traction performance. Additionally, studs can be pinned on the tread to gain extra grip on snow and ice.
When it comes to traction performance – ‘old is gold’! The Cooper Discoverer S/T Maxx surpasses the newer Yokohama Geolandar A/T XD.
ADVANTAGE: Discoverer S/T Maxx
Yokohama Geolandar A/T XD vs Cooper Discoverer S/T Maxx tires on handling
Since all-terrain tires are used on- and off-road, they must offer greater steering command and controllability to the driver. Both Yokohama and Cooper looked very close to each other on the handling front and have ensured that their tires offer great driving stability, seamless turning, confident lane-changing, superior controllability, balance, and turning. In the case of all-terrain tires, you enjoy better driving on paved roads, seamless lane change, and improved control on rough terrains when handling performance is on the good side.
Boasting a solid 8.5 SimpleScore rating in the handling area, the Geolandar A/T XD features a wider, flat, and aggressive-looking tread pattern that ensures seamless maneuvering and better stability in both on- and off-road conditions. The robust sidewall construction of this tire features patented GEO-SHIELD TECHNOLOGY that keeps the sidewall firm and standing even when the tire is being used in challenging conditions for better handling performance and improved steering command. Additionally, the Three Peak Mountain Snowflake certification enhances handling performance in moderate to severe winter weather conditions and the tread can also be pinned with studs for increased control on thick snow or ice.
On the other hand, the Discoverer S/T Maxx is slightly ahead of its competitor with an impressive 8.6 SimpleScore rating. This tire also maintains surefootedness with the kind of flat and wider profile it has. The stud holes present on it provide that extra hold on snowy surfaces, contributing to better ride control. The sidewall structure features Armor Tek3 constructions to avoid deformation during off-roading or high-speed highway driving, and ensuring proper straight-line stability. The tread sports a hybrid 4-5 rib design that provides a balanced ride, while the tread grooves ensure optimum stability when driving in watery or snowy conditions.
Although both tires offer good handling performance, it was the Discoverer S/T Maxx that scored better than the Geolandar A/T XD tire.
ADVANTAGE: Discoverer S/T Maxx
Yokohama Geolandar A/T XD vs Cooper Discoverer S/T Maxx tires on longevity
When buying all-terrain tires, longevity is another important area as it relates to the extended use of the tire. Because of on- and off-road use, all-terrain tires must have a good tread life to serve longer. That’s why we compared both the Geolandar A/T XD and Discoverer S/T Maxx to find out which one was better, and we found that there was a complete shift here.
The Geolandar A/T XD, the comparatively newer tire in the market, got an 8.7 SimpleScore rating in the longevity area. All thanks to the tire’s reinforced GEO-SHIELD construction and solid sidewall armor that prevents the tire from wearing faster than normal. The wide, flat profile of the Geolandar A/T XD distributes driving pressures across the tread for maximum even wear. The tire is built using a high-density compound that provides longer tread life and cut and chip resistance. The mud and stone ejectors present on the tread of the Geolandar A/T XD protect from stone drilling by keeping the grooves and the gaps between the tread blocks clean.
Conversely, the Discoverer S/T Maxx boasts an 8.3 SimpleScore in the longevity area. The tire utilizes patented Armor Tek3 3-ply construction that increases its tread and sidewall robustness to promote longevity and increase the tire’s ability to resist on- and off-road driving pressures. The uniquely angled groove walls and optimized rubber compound reinforce the tire and prevent cuts, chips, and tears for a longer service life. There are also strategically placed stone ejector ribs that prevent stones from getting stuck in the tread and damaging the tire. Likewise, the tread blocks are also hard enough to climb rocks, resist pressures, and promote longevity.
While comparing the longevity scores, we found that the newer Geolandar A/T XD was better than the Discoverer S/T Maxx tire.
ADVANTAGE: Geolandar A/T XD
When to use each
The Geolandar A/T XD and the Discoverer S/T Maxx fall in the all-terrain category, and they are designed for on- and off-road use. Both these tires are engineered year-round compatible, which makes them capable of providing traction in dry, wet, and light winter weather conditions. However, the Geolandar A/T XD offers an additional advantage of performing in moderate to severe winter weather conditions because it is Three Peak Mountain Snowflake certified. The Discoverer S/T Maxx, however, is good for use in light wintry conditions. One good thing is that both tires can be pinned with studs so that better control can be achieved while driving on roads covered with thick snow.
Both the Geolandar all-terrain tires and Cooper all-terrain tires are good for use on light trucks and commercial vans that have 16- to 20-inch rims. Ensure to check the tire size of your drive before ordering either of these tires on SimpleTire.
