5. Street Version of our Racing Tire
A max performance tire with superior handling at maximum speeds of 300 kph
1. Superior Control : The world’s first use of High Grip Silica Compound (HGSC)
technology enables an outstanding grip on the road.
2. Crisp Cornering : Extra wide shoulder blocks and steel reinforced
2-layer carcass ensure tight cornering.
3. Enhanced Durability : 2-ply high density nylon full cover and rayon carcass
provide greater durability for high-speed tires.

2. Wider center block improves steering response
An extra wide center block maintains a steady grip on the road for sensitive steering response.

3. The world’s first use of High Grip Silica Compound (HGSC) for steely grip of the driving surface
Advanced resin technology used for racing tires, HGSC, elevates street driving to a new level.
The use of this technology means resin particles in the tire respond to surface temperature changes.
Higher temperatures move resin particles to the surface and create a super grip on the road for better handling.

9. 2-2. Crisp Cornering 1. Multi-tread radius for balanced grip of
driving surface
A multi-tread radius system delivers sharp, smooth and sure cornering, even at high speeds.
When going straight
When cornering
2. Wide shoulder blocks for lateral stiffness
Wide shoulder blocks help reduce tire distortion while cornering, with increased rubber-to-road contact for greater steering control.

10. 2-2. Crisp Cornering 3. 2-layer carcass for optimal sidewall strength
A 2-layer rayon carcass, in contrast to the standard 1-layer carcass, minimizes lean while cornering for maximum performance tire specifications.
※ Certain smaller specs may have 1-layer carcass

4. High-density bead filler and steel side
reinforcements for cornering control
High-density bead filler and steel side reinforcements, usually reserved for racing tires, lend unsurpassed cornering control.

11. 2-3. Enhanced Durability 1. 2-ply high-density nylon full cover
Treads are fitted with the superior 2-ply high-density jointless nylon full cover for greater resilience, versus the standard 1-ply full cover and edge cover combination.
2. 2-ply rayon carcass
Rayon was used over standard polyester to minimize distortion at high speeds and high temperatures.
※ Rayon carcass only for YR class

12. 2-3. Enhanced Durability 3. Heat alleviation point
High-speed driving generates high temperatures in the shoulder along the belt edge.
Strategically placed heat alleviation points minimize wear and maximize tire performance.

13. 2-4. Reinforced rim guard
A larger rim guard protects wheels from off-road debris and curbs while the knurling inside the rim guard allows the tire to keep a firm grip for full road contact on quick starts and stops.

17. Hydroplaning
Tires manufactured by our competitors show a sharp drop in tire speed when driving above 46 mph (70 kph), with a marked decline in performance on wet driving surfaces. The Ventus R-S2 is built for a stable drop-off from 51 mph
(82 kph) for superior hydroplaning resistance.
