Product Details

The Sumitomo HTR Z5 is a summer ultra high performance passenger car tire engineered to deliver exceptional grip, responsive handling, and confident braking in warm weather conditions. Designed for performance-oriented drivers, this tire combines advanced materials with an optimized tread design to provide the traction and stability needed for spirited driving.

Key Features:

  • Advanced Tread Compound: Specially formulated rubber compound provides enhanced grip on dry and wet surfaces while maintaining tread life
  • Wide Circumferential Grooves: Efficiently evacuate water from the contact patch to enhance wet road traction and boost hydroplaning resistance
  • Optimized Tread Rigidity: Engineered tread block design delivers predictable high-speed stability and precise cornering response
  • Quick Wet Braking: Tread pattern and compound work together to enable powerful wet braking performance when you need it most
  • Y Speed Rating: Rated for sustained speeds up to 186 mph, making it ideal for high-performance vehicles

The HTR Z5 is available in more than 50 sizes ranging from 17 to 20 inches, providing excellent coverage for a wide range of performance sedans, coupes, and sporty vehicles. As a summer tire, it is optimized for warm weather performance and should not be used in near-freezing temperatures, snow, or ice.
