Features & Benefits
-
Feature: O-Bead
Benefit: Improves uniformity and ride comfort through use of a single continuous strand of cable in the bead construction -
Feature: Tube Multi-Cell Compound
Benefit: Improves control on ice by cutting through thin layers of surface water -
Feature: CO-CS (Computer Optimized Component System)
Benefit: Maximizes tire performance by optimizing the appropriate combination of tread design, casing shape, materials, and construction. -
Feature: Independent block tread design
Benefit: Has an Edge Effect to enhance winter traction without having to have traditional metal studs. -
Feature: L.L. Carbon (Long Link)
Benefit: Helps improve tread wear and resist cracking, chipping and tearing through the use of a special long length carbon structure -
Feature: Directional Tread Pattern
Benefit: Maximizes both wet and dry performance, as well as other tire characteristics. By specifying that the tread pattern is to be mounted on the vehicle in a single direction only, the many design compromises found in conventional tires which can be mounted in two directions are eliminated. This provides the ability to include a wider variety of specific performance characteristics such as high resistance to hydroplaning in each tire. -
Feature: Winter Tread Design
Benefit: Delivers safety and control in snow, ice, and cold weather conditions and marked on at least one sidewall with the letters "M" and "S" plus a pictograph of a mountain with a snowflake inside it. -
Feature: Wide Circumferential Center Groove
Benefit: Help maintain good traction on wet and slush-covered roads. -
Feature: Zig Zag Sipes
Benefit: Provides an upgrade to traction on snow and ice.

Tire Technology
Other Tire Technology
Uni-Directional Pattern is a tread pattern design that maximizes both wet and dry performance, as well as other tire characteristics. By specifying that the tread pattern is to be mounted on the vehicle in a single direction only, the many design compromises found in conventional tires which can be mounted in two directions are eliminated. This provides the ability to include a wider variety of specific performance characteristics such as high resistance to hydroplaning in each tire.
Carbon black is a reinforcing material that strengthens rubber. All tire manufacturers use it. But tires with UNI-T technology use L.L. Carbon, an advanced form of carbon black that offers real advantages. Under a microscope, conventional carbon black particles look like bunches of grapes. L.L. Carbon molecules resemble long chains. Think of these as the equivalent of the long steel rods used to reinforce concrete. Because this molecular structure absorbs and spreads road stresses over a larger area, you get a stronger tire better able to resist cracking, chipping, tearing, and excessive wear.
Displaces the thin layer of surface water that can cause a car to slide.
Zig-Zag Sipes are features on the Blizzak winter tires. This leading-edge tread pattern helps improve performance in icy conditions.
This design hasn't always been an exact science. Engineers relied on their experience and various design theories when developing new products. But now, our innovative COCS (Computer Optimized Component System) technology uses a supercomputer to determine the ideal combination of tread design, casing shape, materials, and construction based on consumer benefit criteria. Performing thousands of "what if" calculations and creating incredibly detailed tire simulations, COCS takes the guesswork out of designing tires. COCS makes it possible to create an endless diversity of tire designs to meet the demands of the consumer of today and tomorrow.
If you can imagine the inefficiency of a rolling egg, you can understand the inefficiency of many tire and rim assemblies which are less than precisely round. Now, O-Bead changes the way the tire interacts with the rim, creating a rounder assembly. The "bead" is a cable inside a tire that helps the tire grip on the rim. On most tires, there are overlapped joints where the ends of the bead meet. O-Bead eliminates the overlapped joints by using a single, continuous strand of cable. This helps eliminate tiny, unwanted gaps between the tire and the rim, and creates a rounder tire assembly, for improved driving on straightaways and handling stability.
Spiral Wrap Shoulder Strips are continuous nylon wraps used to reinforce the tire. Placed between the steel belts and the tread, it encircles the entire tire. Unlike the conventional wraps and layers, Spiral Wrap does not have a seam, so the tire is reinforced without having an added stress point which could alter tire shape and have a negative effect on tire performance.
