Ultra-High-Performance Grip With a Contact Patch Built for Cornering
This is the Atturo AZ850 Ultra-High-Performance summer tire in 275/40R19 105Y XL, built around an asymmetrical tread pattern for maximum contact patch and cornering grip. A solid center rib delivers straight-line stability, while large outside tread blocks are positioned to sit toward the curb, remaining rigid under hard cornering loads.
Key Features
- Asymmetrical tread pattern with a solid center rib for straight-line, on-center stability.
- Large outside shoulder blocks designed to stay rigid under hard cornering loads.
- Four main channels move water out of the contact patch to reduce hydroplaning risk.
- Finely siped inside shoulder blocks help reduce road noise.
Fitment
Universal fitment for any vehicle specifying a 275/40R19 tire size with a 105 load index and Y speed rating, most commonly SUVs, crossovers, and sport trucks running this size and rim diameter. Confirm your vehicle's required tire size, load index, and speed rating before ordering.
