Kumho Ecsta V700 (V70A) Competition R-Compound Radial Tire

The Kumho Ecsta V700 — also marketed under the designation V70A — is a DOT-legal R-compound competition radial developed in Europe and imported to the United States. Purpose-built for autocross, track days, and time trials, the Ecsta V700 delivers genuine race-level mechanical grip at a price point that makes closed-course competition accessible to a wide range of drivers. It has built a strong following among autocross competitors, HPDE enthusiasts, and club racers who demand authentic R-compound performance without the premium cost of many rival offerings.

Competition Tread Compound & Design:

• Advanced high-grip silica competition tread compound specially formulated for maximum dry traction on closed-course surfaces
• Directional tread design with wide shoulder ribs and large lateral and center channels engineered to maximize dry cornering grip and deliver consistent, predictable handling balance
• Large circumferential and lateral grooves promote effective water evacuation, helping maintain traction in wet autocross and wet track conditions at full tread depth
• UTQG 50 AA rating — a reflection of the tire's singular focus on maximum grip over treadwear longevity

High-Performance Internal Construction:

• Two wide steel belts deliver exceptional cornering power and a stable, consistent contact patch under lateral load
• Two durable nylon cap plies provide high-speed stability and resistance to centrifugal forces at track speeds
• Robust multi-ply sidewall construction contributes to precise steering response and lateral rigidity
• The directional tread pattern combined with symmetric internal construction allows worn tires to be remounted inside-out on their wheels — extending usable tire life as outer shoulder tread wears from hard cornering

Important Track Use Guidelines:

• Tires must be shaved to 3/32"–4/32" tread depth before dry autocross or track use — running at full tread depth in dry conditions can cause excessive heat buildup and premature localized compound wear or blistering
• Full tread depth is appropriate for wet track and wet autocross conditions only; shaved tires should not be used where standing water or hydroplaning risk is present
• DOT-compliant across all available sizes
• Not intended for highway use, near-freezing temperatures, snow, or ice
• Must be stored indoors at temperatures maintained above 32°F (0°C)

Available across a wide range of fitments to suit a variety of sports cars and performance-oriented vehicles, the Kumho Ecsta V700 stands as one of the most cost-effective entries into the R-compound tire class — delivering the grip, consistency, and track-ready construction that serious competitors demand.
