Compound Softness & Grip
- Supergrip: Balanced grip and durability — great all-around choice. Standard compound on many NSR cars. Lower grip than Ultragrip & Extreme.
- Ultragrip: Softer, grippier — better traction than Supergrip; sticks better especially on plastic tracks. Slightly faster wear.
- Extreme: Softest classic compound — maximum grip, fastest wear, best for peak performance.
- Zero Graining: High, consistent grip with minimal graining — optimized for predictable performance in serious racing; often used in club/one-tire specs.
