2025 ADAC All Season Tire Test P13 of 16

The CST Medallion All Season ACP1's overall driving safety is rated as "deficient" due to significant weaknesses, particularly on winter roads, and it fails to achieve more than a satisfactory rating on dry or wet surfaces. On dry roads, it offers poor steering feedback and is imprecise, requiring corrections and showing a tendency to oversteer, resulting in a barely satisfactory score. On wet pavement, its braking and aquaplaning resistance are satisfactory, but its handling is rated even lower due to a lack of grip and precision. The tire's performance on winter roads is especially poor, with its handling rated as "deficient." It struggles to combine forces, leading to early understeer and oversteer with almost no safety reserves, and it posts the worst result in the test for braking on ice. Environmentally, the Chinese-made tire misses a good rating; while its projected mileage and wear are good, its high weight results in a merely satisfactory efficiency score. Its sustainability is rated as just adequate due to the manufacturer's failure to provide requested ISO certifications or other sustainability credentials.

Performance Analysis

Drawn from 5 tests. Updated October 15, 2025.

Across five all-season tests, the CST Medallion All Season ACP1 consistently finishes in the lower mid-pack with an average position around 21st. Its standout trait is aquaplaning resistance-especially curved aquaplaning-paired with competitive value and decent wear in the latest ADAC test. However, braking performance is repeatedly weak in dry, wet, and especially on ice, which heavily limits overall safety margins.

Overall, the tire suits budget-focused drivers prioritizing hydroplaning security and longevity over outright braking and grip. Persistent bottom-tier braking ranks and elevated stopping distances across years indicate a clear performance deficit in core safety metrics.
