Atturo AZ850 vs Sumitomo HTR Z5 tires on traction

Looking at overviews, both tires seem to be great on the performance front. But, how about their traction performances specifically? Let’s check them out.

First, let’s discuss the traction performance of the AZ850, where it earns an 8.0 SimpleScore. The tire features four wide circumferential channels for seamless water channeling and hydroplaning resistance, which results in better wet traction. Likewise, the inner tread features specialized sipes for increased surface-biting ability on wet roads. Additionally, the wider base and optimized tread help in better traction performance during high-speed driving.

On the contrary, the HTR Z5 is rated a great 8.5 SimpleScore in traction. It features an advanced silica-infused rubber compound for consistent grip and traction on both dry and wet roads in summer weather conditions. The aggressive five-rib pattern and deep grooves help in water evacuation, resisting hydroplaning in rain, and boosting wet grip. Similarly, the rubber compound and tread both enhance the tire’s ability to maintain consistent contact with the road.

Both tires come with great traction abilities, but the Sumitomo tire leads with a better score here!

ADVANTAGE: Sumitomo HTR Z5

Atturo AZ850 vs Sumitomo HTR Z5 tires on durability

Moving on to the handling comparison, let’s find out which of the two tires is better when it comes to handling, ride control, stability, steering response, braking, and cornering in summer conditions.

Starting with the Atturo AZ850, the tire is rated a solid 8.3 SimpleScore for its reliable handling. The tread blocks are tuned to maintain rigidity, and the outer shoulders are durable enough to maintain their original shape while cornering. Thanks to the continuous center rib, the tire offers stable rides and ensures immediate steering response at highway speeds.

On the contrary, the HTR Z5 secures a higher 8.9 SimpleScore for solid handling performance. The tire’s internal construction, featuring high-rigidity steel belts and a tough bead filler promote lateral stiffness for a commanding response behind the wheel. Similarly, the wider footprint with a flat contact patch allows the tire to maintain stability at high speeds.

In handling, we see that the Sumitomo tire again takes a commanding lead, offering better stability and steering response.

ADVANTAGE: Sumitomo HTR Z5

Atturo AZ850 vs Sumitomo HTR Z5 tires on longevity

Let’s now take a look at the long-lasting abilities of these tires and see which controls wear better and offer an extended service life.

Commencing with the AZ850, the tire is rated a good 7.9 SimpleScore in longevity. Since it is a UHP summer tire, it doesn’t come with any tread life warranty. But, its high-tensile construction and heat-resistant rubber compound ensure longer and even wear. Likewise, the wider footprint helps in the even distribution of driving pressures for lasting wear.

The HTR Z5 scores a 7.4 SimpleScore, and considering its performance-specific, the score justifies itself on the positive side. The tire uses an advanced polymer blend to slow down the wear rate, and the wider base complements even wear. That being said, it doesn’t come with any tread life warranty, like the UHP all-season or standard passenger vehicle tires.

The Sumitomo tire took over the Atturo tire in handling and traction areas, but in the longevity race, it is the AZ850 that leads and beats the HTR Z5.

ADVANTAGE: Atturo AZ850
