Cosmo RC-17 vs Sailun Atrezzo SH408 tires on traction

With the overviews of both tires covered, now let’s learn about their traction abilities and find out the best option when it comes to maintaining surefootedness in rain, shine, and mild snow conditions.

First, let’s know a bit about the RC-17, which earns a solid 8.0 SimpleScore for its solid traction in dry, wet, and light snow conditions. The advanced asymmetric tread pattern of this tire features multiple lateral sipes for increased surface-biting ability throughout the year, and the high-void ratio in its grooves promotes optimum water channelling from the contact patch.

On the other hand, the Atrezzo SH408 is rated a 7.8 SimpleScore in traction, assuring reliable performance in rain, shine, and mild winter weather. The symmetric pattern and detailed siping provide solid grip on the road for confident traction, while the four circumferential grooves force water and light slush away from the contact patch to reduce the risk of hydroplaning. During daily driving commuting, the Atrezzo SH408 offers reliable performance.

No doubt, both tires perform well on the year-round traction front, but the lead is taken by the RC-17 because of its slightly better surface-holding ability.
