Kumho Ecsta V700215/40ZR17
The Ecsta V700 (V70A) is Kumho's Racetrack & Autocross Only radial developed in Europe and imported to the United States. The V700 is attractively priced and designed to be a racing value by delivering great traction and treadwear per dollar.
While Ecsta V700 radials meet DOT requirements, they are not appropriate for highway use. Shaved or worn Ecsta V700 radials are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. And like all Racetrack & Autocross Only tires, Ecsta V700 radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It's also essential these tires be stored indoors at temperatures maintained above 32 degrees F.
The Ecsta V700 molds Kumho’s specially formulated, high-grip silica competition tread compound into a directional design that features wide tread ribs to maximize dry cornering grip while enhancing handling and treadlife. Directional tread notches and circumferential grooves help preserve wet traction when run at full tread depth. Kumho advises that the Ecsta V700 Racetrack & Autocross Only radial must be shaved prior to use in dry conditions.
The tire's internal structure includes two steel belts reinforced by nylon cap plies to help stabilize the tread area and provide high-speed capability. A symmetric internal construction featuring three plies in the sidewall enhances quick steering response and high-speed stability.
As the tire’s outer shoulder tread wears from hard cornering, the Ecsta V700’s directional tread design and symmetric internal construction allows worn tires to be remounted “inside-out” on their wheels to prolong their life.
Important Notice: Kumho Ecsta V700 tires must be shaved to 3/32″ – 4/32″ tread depth for any autocross or track use in dry conditions.
If this tire is not shaved, excessive heat and wear may occur causing the tire compound to blister or wear to the cords prematurely in a localized area.
Tire heat cycling will not prevent the excessive localized wear of full tread depth tires but will continue to enhance tire consistency and wear on shaved tires.
The Ecsta V700 should only be used at full tread depth (6/32″) for wet track and wet autocross use.
