Firestone Firehawk Wideoval RFT tire features and benefits illustration
  • Feature: Lateral Grooves
    Benefit: Efficient evacuation and channeling of water that helps reduce hydroplaning and improves wet traction
  • 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: Steel belt construction
    Benefit: Adds durability and resists punctures
  • Feature: O-Bead
    Benefit: Improves uniformity and ride comfort through use of a single continuous strand of cable in the bead construction
  • 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: 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 tread grooves
    Benefit: Evacuates and channels water efficiently to help reduce hydroplaning and to improve wet traction
  • Feature: Silica-based tread compound
    Benefit: Provides outstanding wet performance.
  • Feature: Spiral Wrap
    Benefit: Encircles the whole tire with a continuous nylon wrap , helping the tire hold its original shape to improve high speed capability.
  • Feature: Summer Tread Design
    Benefit: Offers tenacious grip and superior handling on wet or dry roads for driving enthusiasts.
