Nitto Ridge Grappler - All Season Rugged All-Terrain tire
  • Variable Pitch Tread Pattern
  • Shoulder & Lateral Z Grooves
  • Dual Sidewall Design
  • Reinforced Block Foundation
  • Stone Ejectors
  • Staggered Shoulder Lugs
  • Step Block Edges
  • Advanced sound equipment was used to create a pattern that provides a quiet and smooth highway ride.
  • Shoulder grooves are arranged in alternating widths and lengths to clear mud and maintain traction. Lateral Z grooves are set in a zig-zag pattern to provide biting edges for traction.
  • Like all Grapplers, the Ridge Grappler features two bold sidewall designs. One side features a more traditional pattern while the other side features a new, aggressive block design.
  • Adds rigidity to tread blocks to reduce flex.
  • Protects the bottom of groove from stone drilling.
  • Provides traction in off-road environments.
  • The alternating tapered edges and step block edges both provide additional biting edges for more traction.
