Kumho 6302643 Ecsta PS71 EV VA91EV HL275/35R21 105Y Summer UHP Tire with Foam Insert

The Kumho Ecsta PS71 EV (VA91EV) in size HL275/35R21 105Y is an ultra-high-performance summer tire purpose-built for electric vehicles. Featuring a High Load (HL) rating, this tire is engineered to support the increased weight demands of EV platforms without compromising handling precision or ride quality.

A standout feature of this tire is its integrated acoustic foam insert bonded to the inner liner. This sound-absorbing layer significantly reduces road noise transmitted into the cabin — a critical consideration for the near-silent environment of electric vehicles where tire roar is far more perceptible than in combustion-engine cars.

Key Features:

• High Load (HL) Rating: Engineered to handle the added weight of EV battery systems with a robust load index of 105
• Internal Acoustic Foam: Bonded inner foam layer minimizes road noise and cabin resonance for a quieter EV driving experience
• Ultra-High-Performance Summer Compound: Optimized for maximum dry and wet grip at speeds up to 186 mph (Y-rated)
• Optimized Tread Pattern: Designed to reduce rolling resistance to help preserve electric vehicle range
• 21-Inch Fitment: Compatible with modern large-diameter EV and performance vehicle wheels
• Speed Rating Y: Rated for speeds up to 186 mph (300 km/h)

The Kumho Ecsta PS71 EV VA91EV delivers the performance, load capacity, and refinement that today's electric performance vehicles demand, making it an ideal OE-grade replacement or upgrade for EV owners seeking premium summer tire performance.
