The Atturo AZ850 is an ultra-high-performance (UHP) tire engineered for performance sedans, coupes, and sport crossovers, recognized as one of the flagship models that established Atturo's reputation in the large-diameter wheel aftermarket.
The asymmetric tread layout is built around a solid continuous center rib that delivers sharp, linear steering response and high-speed straight-line tracking. Rigid outer shoulder blocks carry heavy lateral cornering loads without flexing, while wide main circumferential channels work alongside oblique lateral grooves to flush standing water from the footprint and resist hydroplaning. The tread is molded from an advanced heat-dissipating rubber compound engineered to manage thermal buildup during high-speed driving while lowering rolling resistance to preserve fuel economy and EV battery efficiency. The compound holds cold-weather grip far better than dedicated summer tires when ambient temperatures drop.
Atturo specifically built the AZ850 line to support the custom and staggered wheel market, offering deep size coverage for large-diameter fitments that many mainstream brands neglect. If you run an aggressive aftermarket wheel setup, this line is often the most direct fit.
Set expectations on coverage and longevity: as is standard for budget-friendly UHP tires in low-profile fitments, the AZ850 does not carry a standalone treadwear mileage warranty, though it is fully backed by Atturo’s standard limited manufacturer warranty against defect. Additionally, as an all-season UHP tire without 3PMSF severe snow certification, it handles cold rain and light slush but is not built for winter ice.
Large-diameter, low-profile performance fitments show inner-shoulder wear rapidly if suspension angles deviate. Check wheel alignment immediately upon mounting and rotate every five thousand miles where fitments permit.
Best-suited for: Dodge Charger, Ford Mustang, Chevrolet Camaro, BMW 3 Series and 5 Series, Audi A6, Tesla Model 3, Infiniti Q50, Lexus IS. Shoppers choose the Atturo AZ850 most often in 255/40R19, 255/35R19, 285/45R20, 285/35R19 and 265/35R20.
