2025 ADAC Summer Tire Test

18th of 18 tires

• The Doublecoin DC100 receives a "deficient" overall rating due to its dangerously poor driving safety performance. While it achieves the best environmental performance score in the test, this cannot compensate for its hazardous handling. On dry roads, it exhibits significant weaknesses, losing performance with increasing temperature, providing poor feedback, and responding slowly to steering inputs, leading to unstable handling and oversteer. Its braking distance is rated as "good." On wet roads, the Doublecoin DC100 fails completely. Its braking performance is so poor that it receives a "deficient" rating. For instance, it requires approximately 45 meters to stop from 80 km/h on wet asphalt compared to about 28 meters for the best tire, a difference of 17 meters. Handling is also "deficient" due to very low grip, early understeer/oversteer, and very long braking distances, resulting in highly imprecise steering. Aquaplaning resistance is rated as "adequate." Despite its poor performance in driving safety, the Doublecoin DC100 achieves the best environmental performance score in the test, mainly due to its very high projected mileage and very low abrasion. It also achieves the top score for efficiency, primarily due to its low fuel consumption. Its sustainability is rated as "adequate.".
