Features & Benefits
-
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: 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: Reinforced Sidewall
Benefit: Support the weight of the vehicle and passenger even with a loss of air pressure with thicker sidewall, generally designed for RFT tires, made of special heat-resistant rubber -
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: O-Bead
Benefit: Improves uniformity and ride comfort through use of a single continuous strand of cable in the bead construction -
Feature: Independent block tread design
Benefit: Has an Edge Effect to enhance winter traction without having to have traditional metal studs. -
Feature: Zig Zag Sipes
Benefit: Provides an upgrade to traction on snow and ice.

Tire Technology
Other Tire Technology
A reinforcing material used in conjunction with carbon black.
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.
Zig-Zag Sipes are features on the Blizzak winter tires. This leading-edge tread pattern helps improve performance in icy conditions.
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.
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.
