Let’s find out which of the two tires is better on the traction front and holds the surface better in warmer weather conditions.
First, we will talk about the AZ850 that secures an 8.0 SimpleScore in traction, assuring good surface holding ability in dry and wet conditions. The asymmetric warm-weather rubber compound of the AZ850 improves road grip on dry roads, especially during acceleration. In rain, the four deep circumferential grooves along with lateral inner grooves force water out of the contact patch to provide solid wet traction and reduce the risk of hydroplaning.
On the other hand, the NT555 G2 is rated an 8.4 SimpleScore in traction. The use of a high-stiffness silica-infused compound and twin center ribs assures increased grip on warmer surfaces, and the wide drainage channels and angled sipes become significantly important features for water displacement and reducing wet braking distances. Additionally, the optimized pattern and compound contribute to confident off-the-line launch traction.
In the traction race, the NT555 G2 surpasses the AZ850 by a small margin.
ADVANTAGE: Nitto NT555 G2
Moving on to the handling part, let’s find out which of the two tires is the leader in ride control, stability, steering response, braking efficiency, and cornering.
Starting with the AZ850, the tire scores an 8.3 for its reliable handling in the summer season. The rigid continuous center rib keeps the footprint intact for better steering response, while the reinforced outer shoulder blocks provide increased cornering stability at high-speed driving.
On the contrary, the NT555 G2 leads the comparison with an 8.8 in handling. The presence of large, tapered shoulder blocks along with a reinforced ply carcass reduces tread block squirm under lateral pressure, while the optimized design provides sports-car-like steering precision, high-speed cornering stability, and immediate on-center response.
In handling, we see that the NT555 G2 again leads, securing a 2-0 win!
ADVANTAGE: Nitto NT555 G2

Let’s now talk about longevity and find out which of the two tires is better at offering value and controlling wear.
Beginning with the AZ850, the tire earns a 7.9 SimpleScore for its decent service life. The flat contact footprint distributes pressure across the contact patch to prevent irregular tread wear. While it misses on the tread life warranty like its most UHP summer tire peers, it has solid inner construction to keep the tire in shape for longer use.
Contrarily, the NT555 G2 is rated a great 8.1 SimpleScore for its long-lasting tread life. This tire is tuned to slow down wear because of its high-rigidity rubber compound and computer-optimized contact patch. The footprint additionally assists in controlling pattern degradation under aggressive driving.
Once again, we see that the NT555 G2 takes the lead in longevity, too, and beats the Atturo tire by a small margin.
ADVANTAGE: Nitto NT555 G2
Both the AZ850 and the NT555 G2 are UHP summer tires, which means they are specially optimized for driving in temperatures above 45 degrees Fahrenheit. None of these tires come with all-season driving abilities, and therefore, don’t consider them for use in winter weather.
As far as rim sizes are concerned, the AZ850 is available in 18- to 22-inch rim choices, while the NT555 G2 comes in 17- to 22-inch rim options.

Looking at overall SimpleScores, the NT555 G2 is a better option than the AZ850 (8.4 vs 7.9). However, your decision to buy tires should be based on your driving style and budget.
As far as the prices are concerned, the AZ850 is available at a starting price of at least $103 per tire, which means a set of four will cost you at least $412. The NT555 G2, on the other hand, is offered at a starting price of at least $166 per tire, which makes a full set of four available at a price of at least $664.
