The Westlake SA37 is an ultra high performance passenger tyre developed for sports cars, performance coupes, and high-powered sedans where drivers demand strong dry handling precision, confident wet-road performance, and direct steering response at a competitive price within the UHP segment. The SA37 features an asymmetric tread pattern with a large continuous outer shoulder rib engineered to maximise lateral grip and cornering stability on dry roads, while wide circumferential grooves and lateral drainage channels on the inner tread zone manage water evacuation efficiently to maintain wet braking performance at elevated speeds. The high-grip UHP compound is formulated to deliver elevated dry adhesion and responsive steering communication suited to the performance demands of high-powered sports cars and coupes. Contact patch load distribution is tuned to maintain consistent grip under the hard cornering and braking forces generated by performance vehicles. The Westlake SA37 delivers genuine ultra high performance handling credentials at an accessible price for drivers who refuse to compromise on dynamic capability.
Best for:
Not intended for: Track or motorsport use requiring a maximum-grip race-derived compound, off-road use, or standard passenger vehicle fitments.
Asymmetric tread pattern with continuous outer shoulder rib: Provides a large, stable contact area along the outer tread edge under dry cornering loads. Delivers maximum lateral grip and precise steering response through fast bends and high-speed direction changes.
Wide circumferential grooves with lateral inner drainage channels: Rapidly evacuate water from the contact patch on wet road surfaces at speed. Maintain wet grip and reduce aquaplaning risk for high-powered performance vehicles in rain.
High-grip UHP tread compound: Formulated to deliver elevated dry road adhesion and responsive steering communication across the temperature range of performance driving. Provides the direct, engaging handling feel expected from an ultra high performance tyre.
Contact patch load distribution tuning: Tread geometry engineered to spread load evenly across the footprint under hard cornering, braking, and acceleration forces. Supports consistent grip levels and predictable handling behaviour at the performance limit.
Accessible UHP value positioning: Delivers the asymmetric tread architecture and UHP compound character of the ultra high performance segment at a price accessible to a broader range of performance vehicle owners. Provides a credible step up from high performance tyres without premium brand pricing.
