Westlake Sport RS 2

The Sport RS 2 is the next generation of the beloved and well-known Westlake Sport RS semi-slick. Initially designed as a drift tire, its soft compound and stiff construction also make it suitable for disciplines such as rallying and time attack. Its undoubted advantage is its price, making it one of the most affordable options for starting your motorsport journey.

What else is worth knowing?

- A sidewall made of a dual-strength composite material combining steel wires with aramid fabric provides increased durability and performance.

- Ultra-wide contact patch for maximum grip.

- Reinforcement layers utilize 2+2×0.25HT steel fabric and 1680 dtex/2 aramid fabric, optimizing contact pressure, length, and width. The contact patch maintains an elliptical shape with minimal deformation, ensuring maximum radial and longitudinal stiffness. This improves load capacity, braking performance, and exceptional high-speed stability, ideal for drifting.

Differences between the Sport RS and Sport RS 2 for size 285/35ZR18:

- SPORT RS 2: Longitudinal stiffness: 961.10 N/mm, radial stiffness: 470.1 N/mm, lateral stiffness: 421.00 N/mm

- SPORT RS: Longitudinal stiffness: 334.70 N/mm, radial stiffness: 280.7 N/mm, lateral stiffness: 190.90 N/mm

This represents increases of 287%, 167%, and 220%, respectively.

Note!

Westlake Sport RS sports tires should not be used or stored at temperatures below 10°C – this can lead to permanent damage to the rubber compound. RacingTires is not liable for damage resulting from failure to follow the manufacturer's recommendations.
