Performance Analysis

CST Medallion All Season ACP1 - Official Image

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.
