The Kumho Ecsta LE Sport KU39 is an ultra high performance summer tyre designed for passenger cars, sports cars, and performance sedans. The tyre features an asymmetric tread design with circumferential grooves that maximise water drainage and resist aquaplaning, along with heat dimples to minimise heat build-up for improved high-speed durability. The KU39 offers excellent grip in both dry and wet conditions thanks to its enhanced resin compound and internal twin steel reinforced belts that deliver stable handling characteristics. The tyre is engineered for responsive handling and provides a quiet, comfortable ride at high speeds while maintaining confidence in wet braking performance. Load and speed ratings vary by size, with common ratings including load index 91-100 and Y-speed rating, indicating suitability for high-speed performance driving. Drivers frequently praise the KU39 for delivering premium-level performance at competitive cost, with strong dry handling and wet grip characteristics.
