2026 ADAC Summer Tire Test
The Ventus Prime4 narrowly misses a good safety rating due to weak wet performance. The summary notes slightly indirect steering on dry roads but good grip. Wet braking, aquaplaning and handling are only fair or sufficient, which leads to early under- or oversteer. The environmental rating is just good thanks to high predicted mileage and low abrasion, although the tire is relatively heavy and noisy. Strengths include good handling at the limit on dry roads, high mileage and low fuel consumption; weaknesses include comfort issues on dry roads, wet-performance deficits and slightly increased weight.
