Features & Benefits

  • 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: Circumferential Grooves And Special 3D Block
    Benefit: Help channel water out of the footprint area to improve resistance to hydroplaning
  • Feature: Summer Tread Design
    Benefit: Offers tenacious grip and superior handling on wet or dry roads for driving enthusiasts.
  • Feature: O-Bead
    Benefit: Improves uniformity and ride comfort through use of a single continuous strand of cable in the bead construction
  • 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: Continuous tread pattern center elements
    Benefit: Promote confident response and braking performance
  • 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: Large outside shoulder blocks
    Benefit: Help deliver better cornering performance
  • Feature: High Grip Tread Compound
    Benefit: Helps to deliver confident dry and wet handling

Tire Technology

UNI-T - Ultimate Tire Technology

What’s this?

Other Tire Technology

Tire Technology 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.

Tire Technology Sipes lengthen to improve new performance on wet surfaces and helps maintain wet performance as the tire wears.

Tire Technology 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.

Tire Technology 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.

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.
