The Kumho Ecsta PS91 is “aimed squarely at supercars and such mouth-wateringly quick passenger saloons.”
The tyre is available in 18 to 20-inch rim diameter sizes in a Y speed rating, and according to Kumho, the focus with the PS91 is on maximum grip and braking performance in the dry, combined with outstanding feel in all conditions. The manufacturer is said to have utilised motorsport technology to create the tread compound, the result being a material that optimises grip and maximises high speed durability. Another factor it employed to aid durability is its ‘3D dimple technology’. This maximises heat dissipation and thus has a positive influence on wear rates. The sidewall also contributes to the tyre’s overall performance through a design that supresses vibration, thereby improving comfort and reducing noise.
Rear fitments for the asymmetric-patterned Ecsta PS91 are endowed with additional block stiffness, a quality best appreciated when fitted to powerful rear wheel drive cars.
