Founded in 1912 in New Jersey, Armstrong is an American tire manufacturer known for its range of durable and high-quality tires. The tire manufacturer focuses on delivering dependable performance through advanced engineering, innovative technologies, and robust tread designs. It caters to the needs of passenger cars, SUVs, CUVs, light trucks, commercial vehicles, and lawn & garden applications.
Atturo, on the other hand, was founded in 2009 and is comparatively a new brand that offers high-quality, aggressive tires at accessible price points. The tire manufacturer prioritizes solid performance, and its range of products is specifically engineered to boost the potential of high-horsepower vehicles, particularly focusing on CUVs, SUVs, and sport trucks.
When it comes to performance-specific tires, both manufacturers have two reliable tires on offer: the Armstrong Blu-Trac HP, an ultra-high-performance all-season tire, and the Atturo AZ850, a dedicated ultra-high-performance summer tire. While the Blu-Trac HP is designed to offer a balance of spirited handling and a quiet highway ride throughout the year, in dry, wet, and mild winter conditions, the Atturo AZ850 is a dedicated ultra-high-performance (UHP) summer tire that offers a grounded, athletic feel and increased stability in warmer weather conditions, specifically in temperatures above 45 degrees Fahrenheit.
If you are in search of a reliable set of performance tires, this Blu-Trac HP vs AZ850 tires comparison will help you choose the perfect tire based on your driving needs, preferences, and budget. To make the comparison between the two tires clearer, we will use our proprietary tire rating system, SimpleScore, to determine each tire’s overall ability, along with its efficiency in areas like traction, handling, and longevity on a scale of 0-10.
Armstrong Blu-Trac HP tires
First, let’s talk about the Armstrong Blu-Trac HP, an ultra-high-performance tire made for use on coupes, sedans, CUVs, and SUVs. The tire sports an asymmetric tread pattern and is tuned for enhanced wet-weather performance. It adapts to varying temperatures, rain, shine, and mild snow weather conditions, to be specific. The footprint and construction contribute to better high-speed stability, and the use of advanced noise-reduction technology further scales the driving pleasure and ride comfort.
Overall, the Blu-Trac HP is rated a great 8.1 SimpleScore, thanks to its impressive longevity, reliable handling, and balanced traction.

Atturo AZ850 tires
The rival, Atturo AZ850, is an ultra-high-performance summer tire specifically tuned for CUVs, SUVs, and light trucks, and it offers solid performance in summer conditions on dry and wet pavement. It features an asymmetric tread design and an optimized construction for confident cornering, hydroplaning resistance, and low tread noise. The tire’s construction is also tuned to prevent deformation under high-speed stress. Additionally, low rolling resistance and better heat resistance make it a great choice for use in temperatures above 45 degrees Fahrenheit.
Overall, the AZ850 earns a solid 7.9 SimpleScore because of its athletic handling, reliable summer traction, and good service life.

Armstrong Blu-Trac HP vs Atturo AZ850 tires on traction

With the overviews of both tires covered, let’s now compare their traction performances and find out which one wins when it comes to maintaining surefootedness.
Commencing with the Blu-Trac HP, the tire is rated an 8.0 SimpleScore in traction, assuring solid year-round traction and grip. The tire utilizes a specialized silica rubber compound and deep circumferential grooves that offer increased grip on wet surfaces. Likewise, the lateral grooves are optimized to force water away from the contact patch and prevent hydroplaning. Additionally, there are subtle sipes that enhance grip in mild snowy conditions.
On the other hand, the AZ850 is rated an 8.0 SimpleScore in traction, though it is specific to wet and dry conditions (no snow grip, as it is a summer tire). The tire utilizes four wide circumferential channels to push water away from the tread area and offer better grip in rain and prevent hydroplaning. The inner tread comes with specialized sipes for increased biting ability and provides high-speed grip on highways in warmer weather conditions.
In traction, we see that both tires score equally great, resulting in a tie!
ADVANTAGE: Tie
Armstrong Blu-Trac HP vs Atturo AZ850 tires on handling

Coming to the handling analysis, let’s figure out the better tire in terms of ride control, stability, steering response, braking, and cornering.
The Blu-Trac HP earns an 8.3 SimpleScore in handling, assuring a commanding controllability in dry, wet, and light snow conditions. The block rigidity, including the solid outer shoulder, ensures the tire remains in its original shape during high driving pressures and offers a confident steering response. Likewise, the center rib design also contributes to better stability and seamless maneuvering on highways.
Conversely, the AZ850 secures an equal 8.3 SimpleScore for handling, offering seamless performance in warmer weather on both dry and wet pavement. The larger outer shoulder blocks provide increased contact with the surface for crisp steering and high-speed stability. Thanks to the reinforced internal structure, the tire ditches deformation for confident cornering and sharper lane changes in warmer weather.
In the handling race too, we see there’s a tie in both tires; however, their ability to use in specific weather conditions should be taken into consideration for optimal performance in this area.
ADVANTAGE: Tie
Armstrong Blu-Trac HP vs Atturo AZ850 tires on longevity
Long-lasting ability relates directly to the value drivers get from their tires. Here, in this section, we will find out which tire is better in terms of controlling wear and covering more miles.
Starting with the Blu-Trac HP, it scores an 8.4 SimpleScore in longevity and is also backed by a 45,000 mile limited manufacturer tread life warranty. Both the SimpleScore and the tread life warranty are an assurance that the tire is great on the long-lasting front and resists wear optimally. Thanks to its optimized footprint, the driving forces are evenly distributed to resist irregular wear and promote an extended service.
Contrarily, the AZ850 secures a 7.9 SimpleScore in longevity, indicating a good service life. Like most UHP summer tires, the AZ850’s rubber compound is also designed for high grip rather than long-lasting mileage. It also doesn’t come with a tread life mileage warranty, which is very standard in the case of UHP summer tires. However, its high-tensile construction and heat-resistant compound contribute to resisting uneven wear.
In the longevity race, the UHP all-season tire, the Blu-Trac HP, excels with a higher score and a backing of tread life warranty.
ADVANTAGE: Armstrong Blu-Trac HP
When to use each
Both the Blu-Trac HP and the AZ850 are performance tires; however, they serve slightly different needs. While the Blu-Trac HP is a UHP all-season suitable for year-round use in dry, wet, and mild snow conditions, the AZ850 is a UHP summer tire that should always be used in summer weather conditions, in temperatures above 45 degrees Fahrenheit.
As far as rim sizes are concerned, the Blu-Trac HP is offered in 15- to 20-inch rim sizes, and the AZ850 is offered in 18- to 22-inch rim sizes (primarily focusing on performance-tuned SUVs and CUVs).
Which one should you choose?

Looking at the overall SimpleScore, the Blu-Trac HP is a slightly better choice than the AZ850 (8.1 vs 7.9). However, your selection should be based on your vehicle type and whether you need a UHP tire with year-round utility or with dedicated summer performance abilities.
Talking about prices, the Blu-Trac HP is available at an initial price of at least $53 per tire, while the AZ850 is offered at a starting price of at least $91 per tire. This means a set of four Armstrong tires starts at at least $212, whereas a set of four Atturo tires will cost you at least $364.
Based on SimpleScore, you should choose the Armstrong Blu-Trac HP if you:
- Drive vehicles like the BMW 5 Series, Audi A6, or Lexus RX.
- Prefer a tire that’s better in longevity (8.4 vs 7.9).
- Need a tire that’s covered by a 45,000 mile limited manufacturer tread life warranty.
- Want a tire that’s more affordable.
- Need a tire that can be used year-round.
On the other hand, you should choose the Atturo AZ850 if you:
- Drive vehicles like the Porsche Cayenne or Jeep Grand Cherokee.
- Want a dedicated summer tire for enhanced steering response in warmer weather.
- Need a tire that’s available in larger 22-inch rim sizes for a custom-wheel build.
