Nitto Ridge Grappler - All Season On/Off-Road Maximum Traction 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.
