Summary

Description

The CST Medallion MD-A1 is a premium summer touring tire engineered for passenger vehicles, blending sport-oriented handling with refined comfort. Its asymmetric tread pattern integrates large, rigid shoulder blocks and bidirectional Z-shaped grooves to enhance wet traction and reduce aquaplaning risks. A closed outer shoulder design minimizes road noise, while a high-silica compound optimizes dry and wet grip, fuel efficiency, and tread longevity.

Features & Benefits

  • Asymmetric Tread Design: Large tread elements and optimized profile maximize contact patch area, improving cornering precision and reducing uneven wear.
  • Z-Shaped Drainage Grooves: Enhance water evacuation for superior wet braking and resistance to hydroplaning.
  • Closed Shoulder Design: Reduces noise levels for a quieter driving experience, particularly on highways.
  • High-Silica Compound: Balances dry/wet grip with low rolling resistance, supporting fuel efficiency and responsive handling.

Year Released

Launched in 2018, the MD-A1 remains CST’s flagship summer touring tire in targeted markets.

Regions Availability

Distributed in Central America, South America, and Europe.

Vehicle Compatibility / Popular Vehicle Fitments

Available in 15”–19” diameters, the MD-A1 fits compact cars, sedans, and performance vehicles, including:

  • Europe: Volkswagen Golf, Audi A3, BMW 3 Series, Mercedes-Benz A-Class
  • Central/ South America: Chevrolet Onix, Ford Ka, Hyundai HB20, Honda Civic
  • Premium Models: Audi A4, BMW 5 Series, Mercedes-Benz C-Class (compatible with 17”–19” sizes)

Note: Always consult a tire specialist or vehicle manufacturer to confirm fitment.

Final Thoughts

The Medallion MD-A1 targets drivers in warm climates seeking a balance of sporty agility and touring comfort. Its asymmetric tread and silica compound deliver confident dry/wet performance, though it lacks winter certification (3PMSF) for cold conditions. The tire’s noise reduction features and EU-compliant fuel efficiency make it ideal for urban commuters and highway travelers. While not a track-focused option, it competes well in its segment for drivers prioritizing everyday usability over premium branding. For budget-conscious buyers in Europe and the Americas, the MD-A1 offers a cost-effective summer solution with minimal compromises.
