This listing is for new Atturo AZ850 255/50R20XL 109Y BSW Tires. Manufacturer part number: AZ850-A7EJ0AFE.
The Atturo AZ850 is an ultra-high-performance summer tire designed for SUVs, crossovers, and light trucks, offering a balance of performance, comfort, and fuel efficiency. Its asymmetric tread pattern enhances both dry and wet traction, making it a reliable choice for maximizing summer driving potential. The tire’s construction reduces rolling resistance, improving fuel economy and extending tire life.
A continuous center rib ensures precise steering and braking, ideal for straight-line stability and smooth highway driving. The outer tread blocks, designed for high-speed cornering, provide confidence during sharp turns. The AZ850's special rubber compound dissipates heat efficiently, promoting longer tread life and high-speed performance.
In wet conditions, the AZ850 features wide circumferential grooves and oblique lateral grooves that channel water away, reducing hydroplaning and ensuring strong wet traction. Whether in light drizzle or heavy rain, the AZ850 maintains grip and stability.
