- Dual Sidewall Designs - Each Grappler has two sidewall designs so you can choose how your tires look. On the Dura Grappler one side has a metal fin design and the other has a traditional design. This feature was an engineering feat since even a small weight imbalance can cause unwanted vibrations. See how Nitto produces exceptionally uniform off-road tires even with different designs. - Dura-Belt Technology - Dura-Belt three steel-belted technology* provides long tread life, in addition to offering good handling performance. - Up to 60,000-Mile Treadwear Warranty - The Dura Grappler is engineered to help you make the most of your on-road driving. Its internal construction, wear-oriented compound, and tread design were purposefully engineered to maximize treadlife. In fact, each P-Metric/Metric size is backed by a 60,000-mile limited treadwear warranty and each Dura-Belt size is backed by 45,000-mile warranty. - Specific Patterns to Meet Your Needs - The Dura Grappler is also offered in two separate tread pattern dedicated for LT-Metric sizes and P-Metric sizes. LT-Metric sizes are offered in a durable 4-rib design, while the P-Metric sizes have a quiet 5-rib design. - Longevity - The multi-rib pattern helps improve tread life by linking the tread blocks to reduce tread flex, and also results in a quieter tire. - Advanced Siping Technologies - Waved sipes increase traction in wet conditions while maintaining tread block rigidity - Wet Performance - Circumferential grooves evacuate water from the tread pattern to maintain road traction in wet and slushy conditions.
