Atturo AZ 850 Tire - 285/40R21 109Y XL

Atturo AZ 850 Tire - 285/40R21 109Y XL

Engineered for ultra-high-performance driving, the Atturo AZ 850 features an asymmetrical tread pattern designed to maximize the contact patch for responsive handling and confident grip across demanding street and performance applications.

• Solid center rib provides directional stability, helping the tire stay planted at high speeds and under braking.
• Large outside tread blocks enhance cornering ability, delivering precise steering response and improved lateral grip.
• Shoulder tread blocks remain rigid under stress for precise and predictable turning, even when pushed hard.
• Inside shoulder blocks diffuse road noise and allow water to flow out of the contact patch, contributing to a smoother ride and improved wet performance.
• Center tread remains rigid under stress for consistent turning response (predictable handling under load).
• 48 main channels flush out water to provide traction and help resist hydroplaning for confident wet-weather performance.

Specifically designed for 285/40R21 sizing with a 109Y XL load/speed rating, the AZ 850 is built to deliver steady handling, controlled dynamics, and improved stability when you push the pace on modern performance SUVs and trucks.
