Product Details

The Sumitomo HTR Z5 is a summer ultra high performance tire engineered for drivers seeking exceptional grip and responsive handling in warm weather conditions. Designed for passenger cars and sports sedans, this tire delivers the performance characteristics demanded by enthusiasts without compromising everyday drivability.

Advanced Performance Features:

  • Advanced Tread Compound: Specially formulated rubber provides superior traction and quick response in dry and wet conditions while maintaining excellent wear characteristics
  • Wide Circumferential Grooves: Four deep grooves evacuate water efficiently to enhance wet road traction and boost hydroplaning resistance, enabling confident driving in rain
  • Optimized Tread Rigidity: Strategically designed tread blocks provide predictable high-speed stability and consistent contact with the road surface during aggressive cornering
  • Y Speed Rating: Tested and approved for sustained speeds up to 186 mph, making this tire suitable for high-performance driving applications

The HTR Z5 offers an ideal balance of performance, comfort, and value for drivers who demand more from their tires during the summer driving season. This tire is designed exclusively for warm weather use and should not be driven in near-freezing temperatures, ice, or snow conditions.
