High Performance Pattern Pattern Design

1. Development Background 1.1 Concept 1.2 Evolution of hankook High Performaces tyres

1.1_Concept High Performance Optimo K415 performs great A special pattern generated through computer simulation is designed for a smooth, safe ride in rain. HGS compound technology empowers outstanding braking capability on wet roads, you with precise handling ability, rain or shine… Optimo K415 It is your summer companion for mid-size sedans. Relax and experience driving like it should be in any road conditions

2. Features 2.1 Tread Design 2.2 Compound 2.3 Construction

2.1_Tread Design High Performance 4-Channel-Drainage Wide Center Rib The optimal width and positioning of the four channel grooves ensure safety on wet roads. Wide Center Rib for superior handling and shorter braking distances. Lateral Shoulder Grooves Designed to improve handling on dry roads and reduce then any decline in performance under rainy conditions and ride. Shoulder Rib Block Minimizing vibrations for greater ride comfort and more precise handling.

2.1_Tread Design High Performance Ideal Use of Grooves The number and width of the straight grooves are optimized according to the tread width to deliver a superior handling and hydroplaning performance. 4 channels for tyres 185 mm and wider 3 channels for tyres up to 175 mm wide • 175/65R14, 175/65R15 exception

2.1_Tread Design High Performance Hydroplaning Resistance The tyre contact area on the wet surface is clearly expressed in black, while the blurred parts show where the tyre is separated from the road surface by water. The greater the black area, the better water is channeled away. This helps the tyre to resist hydroplaning and improve handling and braking performance in wet weather.

2.2_Compound High Performance HGS (High Grip Silica) Compound Technology HGS increases molecular movement in the tread, which leads to a more flexible adaptation of the tread compound to the road surface. This brings more rubber on the road, resulting in better grip and therefore more safety.

2.2_Compound High Performance Special Resin The use of a special resin increases the tyre’s interaction with the road surface. Migrating resins in the tyre’s surface ensure maximum stickiness and outstanding grip.

2.3_Construction High Performance SCCT Mold Profile The application of our advanced SCCT (Stiffness Control Contour Theory) mold profile delivers uniform contact pressure on the center and shoulder blocks for shorter braking distances.

2.3_Construction High Performance New Bead Profile Minimal gap between rim and bead + Even spread of contact pressure = Improved comfort and precise steering Uniformity in circumferential Gap Gap

2.3_Construction High Performance Optimized footprint through computer simulation Creating the ideal footprint during driving and braking ensures steering stability and even wear. When driving When braking

2.3_Construction High Performance Jointless Cap Ply Improving uniformity for a smooth ride and higher durability. Wide, High-Tensile Steel Belts Enhancing tread strength for a more direct steering response and less wear. Jointless Bead Wire & High Tensile Modulus Bead Filler Improving high speed stability and ride comfort. Maximizing steering response and durability.
