In the latest ADAC summer tire test, 18 models in the popular 225/40 R18 size were tested. This size is common on vehicles such as the VW Golf, Audi Q3 or the BMW 1 Series, and many others. Interesting is that 11 of the tested tires received an overall “good” rating, including some budget-friendly options.

Standout Performers
Leading the pack were the Continental SportContact 7 (★100) and the Bridgestone Potenza Sport (★91), both of which scored an outstanding 1.5 for dry-road safety and excelled in wet conditions. The Michelin Pilot Sport 5 (★96) and Goodyear Eagle F1 Asymmetric 6 (★93) also delivered strong performances, with Michelin earning extra praise for its wear and environmental efficiency, which is something Michelin aims for in the last years. Additionally, brands like Vredestein, Yokohama, Firestone, Falken, and Nexen secured “good” ratings. These models not only delivered commendable performance but also came with a more attractive price tag compared to their premium counterparts, which make them an interesting options to consider.
Longevity vs. Grip Trade-Off
An intriguing aspect of the test was the balance between durability and traction, which we also like to emphasize. A good example is the Doublecoin DC100, which clocked an impressive 74,400 kilometers in wear tests. That it wasn’t magic became evident in the grip and handling tests, which proved that its longevity was simply due to a very hard rubber compound. While this reduces abrasion, it compromises grip and handling—especially on wet surfaces. This example underscores that a longer tread life doesn’t necessarily mean better overall safety or performance.
The Weakest Link Factor
ADAC’s comprehensive scoring system ensures that no single deficiency is ignored. Even if a tire excels in several areas, a notably poor performance in a critical category—such as braking or handling—can drag down its overall rating. This “weakest link” approach guarantees that every tire recommendation reflects a balanced evaluation of both strengths and shortcomings.
