5-pitch-noise-reduction5 Pitch Noise Reduction is a specialized approach to tread pattern design that reduces tire noise levels for quieter driving. Tread block elements are arranged to produce noise, canceling sound waves when the tire is in motion.

weathergrip-hp-tread-compoundWeatherGrip HP Tread Compound is a special performance tread compound formulation containing SBR and L.L. Carbon in a blend designed to promote long-wearing durability and outstanding wet performance without sacrificing dry performance.

multicell-threadDisplaces the thin layer of surface water that can cause a car to slide.

co-csThis 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.

epoEPO integrates the two leading-edge technologies, Dual-Layer Tread and EPC, to help provide excellent performance as the tire wears.

power-vPower V Tread Pattern is derived from our original Indy racing rain tire. By dispersing water out from the center of the tire, the specially-angled, v-shaped pattern elements create improved water discharge. This results in better contact with wet roads, for outstanding wet performance and reduced risk of hydroplaning.

spiral-wrapSpiral 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.

hesH-E-S (Hydro Evacuation Surface) reduces the risk of hydroplaning leading to better wet performance.

o-beadIf 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.

epcEPC Tread Compound is a unique rubber compound that fights the effects of friction-related rubber hardening. Friction-related rubber hardening is one of the reasons tires lose wet-surface performance as they wear.

key-hole-sipeA Key Hole Sipe is a slot with a cylindrical channel at the base. In a cross section of the tire tread, this slot-and-channel configuration resembles a key hole. As the tread wears, the "key holes" emerge to help ensure a consistent tread pattern. These sipes help maintain continued wet performance and new tire appearance.

rim-guardRim Guard (45, 50, & 55 Series Tires) is a tough, raised rubber ridge that encircles the entire sidewall. Rim Guard protects wheels from damage by curbs and other objects.

uni-directionalUni-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.

zig-zag-sipesZig-Zag Sipes are features on the Blizzak winter tires. This leading-edge tread pattern helps improve performance in icy conditions.

cscC-S-C is a pattern of tread blocks designed for uniform contact pressure, improving dry and wet handling, reducing irregular wear, and resulting in better ride comfort.

ll-carbonCarbon 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.

dual-layer-treadDual-Layer Tread was developed to ensure that tires maintain wet performance as they wear. Tires with Dual-Layer Tread have two kinds of rubber in the tread, both containing EPC. As the tire wears, a higher grip layer is exposed. This minimizes the effect of wear on worn wet tire performance and helps maintain more consistent handling. It also helps prevent the increase in noise that tends to occur as the tread wears.
