The ECSTA V700 is the newest competition
tire member of the Kumho high performance tire family. It's a
DOT-legal competition radial that was developed in Europe & is now
available in the United States for drivers who participate in
autocross & track events. Like its companion (the Kumho V700
VictoRacer), the ECSTA V700 is attractively priced & designed to
be a great racing value by delivering the best traction &
treadlife per dollar.
V700 molds Kumho's specially formulated, high grip Silica
competition tread compound into a directional design that features
wide tread ribs in the shoulders & intermediate tread blocks to
maximize dry cornering grip while enhancing handling & tread life.
The ECSTA V700's directional tread design also helps provide wet
traction when run at full tread depth. However, if there is a lot of
standing water on the track, caution is advised and/or the use of
deeper treaded tires is recommended. The ECSTA V700 is molded with
6/32" of tread depth in its two major circumferential grooves.
The ECSTA V700 has two steel belts
reinforced by two nylon cap plies to help stabilize the tread area
& provide high speed capability. Additionally, a symmetric
internal construction featuring three plies in the sidewall enhances
quick steering response & high speed stability. As the tire's
outer shoulder tread wears from hard cornering, the ECSTA V700's
directional tread design & symmetric internal construction allows
worn tires to be remounted "inside-out" on their wheels to prolong
Kumho ECSTA V700 tires must be shaved to 3/32" - 4/32" tread depth
for any autocross or track use in the dry.
Kumho advises that the ECSTA V700
DOT-legal competition radial must be shaved prior to use in dry
conditions. If this tire is not shaved, excessive wear may occur
causing the tire to wear to the cords prematurely in a localized
Tire heat cycling will not prevent
the excessive localized wear of full tread depth tires but will
continue to enhance tire consistency & wear on shaved tires.
The ECSTA V700 should only be used at
full tread depth (6/32") for wet track & wet autocross use.
