The “SOLUS 4S HA32” is a four-season tire developed with performance optimized for environments in the U.S.A. It is a product that satisfies all consumers by enabling road driving with balanced and continuous performance. It improves both driving performance on road surfaces in various weather conditions and traction by more than 15%, especially on wet road surfaces, thus enabling safe driving. In order to improve handling and braking on snowy roads, our unique structural design and compound technology were applied, and a directional tread pattern design differentiated from competitors' products was applied in consideration of market trends.

The “HA32” adopts a directional tread pattern design concept to enable safe driving on snowy roads as well as improved drainage performance on wet roads for optimal performance in four-season climate environments. This reflects the latest trends in the competitive product market and applies a design technology differentiated from existing products to improve braking performance on wet roads and traction on snowy roads.

A three-dimensional holographic graphic sidewall design was applied to the side of the tire to add future-oriented value in line with the electrified vehicle trend. This is a design element that expresses the unique identity of the product as a part exposed to the outside when the tire is mounted on a vehicle, which increases the user's emotional satisfaction and gives a luxurious image of the product.

The latest compound technology developed based on natural resin components is applied to improve grip performance on the road in all seasons, improving traction and safety on snowy roads. It also improves handling performance on dry roads and braking power on wet roads by more than 10% compared to existing products. The latest structural technology enables a uniform ground shape, which improves the ground area by more than 10% compared to existing products and enhances braking performance on dry road surfaces.

The “HA32” has an hourglass wear indicator technology that allows users to easily check the wear level of tires. This prevents accidents caused by the use of old tires by indicating the tire wear process in the shape of an hourglass in advance to notify when to replace the tire. In addition, a 3D Sipe that reinforces the tread block stiffness was applied to improve driving performance on dry road surfaces, and an asymmetric stiffness reinforcement structure was applied to the center block to improve the straight driving performance at high speed.
