The Kumho Solus 4S HA32 is a Grand Touring All-Weather tire developed for passenger cars, coupes and crossovers looking for capable traction in all weather conditions throughout the year, meeting industry severe snow service requirements with Three Peak Mountain Snowflake (3PMSF) certification. This tire incorporates Kumho's latest 4 seasons winter approved tire compound enabling an increase of 15% on wet surfaces as well as an improvement of 10% during both dry and wet driving conditions.
Advanced Tread Design:
The Solus 4S HA32 features a pine-resin infused rubber compound molded into a V-shaped directional tread pattern, with the points of each individual "V" working together to form the tire's center rib, connected with 3D sloped tie-bars for straight-line rigidity, quick handling and a solid on-center feeling, while the channels expand toward the shoulder for efficient water evacuation to fight hydroplaning in rainy weather. The tire utilizes five different types of sipes, including interlocking 3D sipes in the tread blocks to resist deformation, while providing a multitude of additional biting edges to maximize winter traction and safety.
