Kumho Ecsta PS31 Tire Review

The Ecsta PS31 has a directional tread pattern with a continuous center rib and stylish lateral grooves that add to stability in high speed driving, while also increasing block stiffness and enhancing wet braking capabilities.

A unique 3D dimple design is created to minimize the buildup of heat in the tread blocks. This is an area that plagues many high-speed tires. Another benefit to this design is a longer treadlife due to the heat reduction.

Wet traction is increased through the tire’s optimized wide lateral groove angles and four wide circumferential grooves around the tread. The grooves reduce the risk of hydroplaning, while diagonal sipe micro-grooves further improve wet grip and overall handling, particularly during harder cornering.

Inside the tire are two steel belts with a two-ply polyester casing beneath them. Two full layer nylon cap plies increase impact resistance, high-speed handling and durability.

Kumho currently offers a range of 14-18 inch sizes, and all sizes feature either a V or W-speed rating. A limited tread warranty is also part of the package.

  • 3D dimple design reduces heat buildup and furthers treadlife
  • Handles and corners with some of the better tires in this class
  • Value priced

Overall Thoughts

The Ecsta PS31 sidewall’s racing-inspired design and the stylish tread pattern speak volumes in looks alone on this UHP capabilities of this tire. Where this tire excels would be in its dry and wet traction, as well as cornering grip and stability. In addition, the steering is responsive and delivers good feedback at higher speeds.

Potential problem areas would include a little extra road noise as the tire starts to wear down. That said, it’s nothing so excessive that it would prevent us from running this tire. Naturally, this is a summer UHP tire and is not designed for winter driving or on freezing pavement.
