Features and Benefits

Feature: Sidewall rubber reinforcement
Benefit: Helps the tire continue running when flat
Feature: Dual Layer Tread
Benefit: As the tire wears, more of the inner tread is exposed so the tire continues to have excellent grip in wet conditions.
Feature: Reinforcing Agent
Benefit: Reinforcing material used in conjunction with carbon black
Feature: Unidirectional Pattern
Benefit: Mounting tires in a single direction improves wet and dry performance and helps prevent hydroplaning.
Feature: Spiral Wrap
Benefit: Spiral Wrap is a continuous nylon wrap that encircles the whole tire, helping the tire hold its original shape to improve high speed capability.
Feature: Innovative Compound - Longer Is Stronger
Benefit: L.L. Carbon utilizes a special form of molecular re-engineered carbon black, a key factor in improving tire wear while enhancing wet performance.
Feature: EPC Tread Compound
Benefit: Reduces the hardening effects of heat for continued flexibility and wet performance as the tire wears.
Feature: Power V Tread Pattern
Benefit: A design developed from the Firehawk Indy Racing rain tire to discharge water for better contact with wet roads and reduced risk of hydroplaning.
Feature: Rim Guard
Benefit: A raised rubber ridge acts like a bumper to protect wheels from curb damage.
Feature: Innovative Roundness - Rounder Is Better
Benefit: Rounder overall tire shape provides better balance for wet or dry handling.
Feature: Innovative Tire Design - A Comprehensive Tire Design Method
Benefit: This method improves handling in wet or dry conditions and reduces irregular treadwear by combining an ideal tread design, casing shape, materials and construction.
Feature: 3-ply body construction
Benefit: Adds durability, allowing the tire to continue running for up to 50 miles at 55 mph
Feature: 5 Degree Noise Reduction
Benefit: Produces noise-canceling sound waves to significantly reduce the noise on road surfaces.
Feature: EPO (Extended Performance Optimization)
