Atturo 50036 AZ850 Ultra-High Performance Summer Tire

The Atturo AZ850 is an ultra-high performance summer tire engineered for drivers who demand sharp handling, strong grip, and a composed ride from their SUV, CUV, crossover, or performance car. Built around a summer-focused compound and an advanced asymmetric tread architecture, the AZ850 delivers confident control in both dry and wet conditions without sacrificing everyday comfort.

Key Features:

• Asymmetric Tread Design: Different inside and outside tread contours optimize the contact patch for maximum dry grip while maintaining dedicated water-evacuation channels for wet-weather traction
• Solid Center Rib: A continuous center rib enhances straight-line stability and steering response at highway speeds
• Large Outer Shoulder Blocks: Rigid, reinforced outer blocks resist flex under hard cornering, improving lateral grip and cornering precision
• Fine-Slice Inner Tread Blocks: Finely siped inner shoulder blocks channel water away from the contact patch and significantly reduce road noise
• Four Main Circumferential Grooves: Wide grooves rapidly evacuate water to minimize hydroplaning risk on wet roads
• Oblique Lateral Grooves: Angled lateral grooves improve water dispersal efficiency and further protect against wet-weather loss of traction
• Silica-Enhanced Compound: The summer-focused rubber compound improves wet traction and reduces rolling resistance for improved fuel efficiency
• Reinforced Sidewalls: Added sidewall reinforcement enhances durability and high-speed stability during aggressive driving maneuvers
• Jointless Nylon Cap Ply: An industry-standard nylon band over the steel belts restricts belt movement at speed, anchoring the contact patch to the pavement for consistent high-speed performance
• 3-Year Manufacturer Defect Warranty: Covered under Atturo's standard 3-year limited warranty for the original purchaser

The AZ850 is a summer tire and is not rated for winter or severe snow service. Performance may be reduced in temperatures below 45°F as the summer compound stiffens in cold conditions. Available in 18- through 22-inch rim diameters to fit a wide range of modern performance vehicles.
