Tire Size: 245/40ZR18 Fits: COBRA INSTINCT It is an all-season, all-terrain tire with commercial level traction. It is designed to perform on tough terrains with unmatched stability and responsiveness. Its unique tread pattern offers a quiet and comfortable ride. It stands up to heavy workloads, is durable and has a long tread life. Hybrid 4-5 rib design controls noise and maintains even tire wear.Buttress tire design supports off-road grip, durability, and prevents punctures. Dual-draft, non-parallel groove walls decrease stone retention and protect from damages.Stone ejector ribs discharge debris and control stone retention. Features:

Deep original tread depth: Keep stones and debris out of the grooves to help resist irregular wear and enhance durability.
Sidewall protector bars: Help shield the casing from scrubbing and curbing, while maintaining a smooth, comfortable ride at highway speeds.
Casing innovations: Zenvironment technology allows us to predict changes in tire shape that occur in early stages of wear, resulting in stabilized performance, providing longer casing life and better retreadability.
Block-Shaped stone guards: Prevent stones from traveling to the bottom of the grooves, reducing damage to the casing by 25% to ensure high durability and retreadability.
Serpentine groove pattern: Designed specifically to reduce premature shoulder step-down and irregular wear, further preserving overall treadlife.
Ultra-Wide top steel belt: Increases rigidity across the entire tread surface, for enhanced durability and to avoid casing damage.
Unique rubber compound: Produces stronger, more pliable rubber that improves treadwear and provides low rolling resistance for better fuel efficiency.
