Sumitomo HTR24 HTR Z5 275/35ZR20 102Y XL Ultra High Performance Summer Tire

The Sumitomo HTR Z5 is an Ultra High Performance Summer tire designed for drivers of sports cars, sporty coupes and performance sedans seeking responsive high-speed handling and confident traction in warm weather conditions. Introduced in 2019 as the successor to the HTR Z III, this tire delivers outstanding dry road grip and wet weather capability for enthusiastic drivers.

Advanced Tread Design:

• Notches in intermediate and center ribs combine with tread compound for traction in wet conditions

Internal Construction:

• Two-ply polyester casing supporting two high-rigidity steel belts with full-width nylon reinforcement ply for high-speed stability
• High-modulus bead insert strengthens the sidewall to aid handling performance
• Optimized tread rigidity provides predictable high-speed stability

Performance Benefits:

• Outstanding dry traction and confident grip with responsive handling in corners
• Strong wet performance with impressive hydroplaning resistance
• High marks for smoothness and low noise, enhancing daily driving comfort
• Y-speed rated for sustained speeds up to 186 mph
