Sonar's SX-9 is an all-season tire that's designed to give drivers increased grip on straightaways along with strong performance on wet roads.

Features & Benefits

• Zigzag center rib design increases grip performance on straight way.
• Four broad circumferential groove design with 35% void ratio enhances drainage efficiency and maneuverability on wet road condition.
• Broad circumferential groove design (outside groove wall angle>inside groove wall angle) drains water more easily, and even prevents slipping
• 3-Dimension arc groove design between blocks helps increasing stiffness between blocks, and also disturbs air flow in grooves
• Adding sipes and thin grooves on blocks and shoulders balances block stiffness and riding comfort.
• Applying “groove in groove” concept on circumferential grooves disperses stress on tire surface, and prevents irregular wear and noise produced by the friction between air flow and groove wall
• Separating circumferential grooves and radial grooves decreases rolling noise.
