πŸ’‘ Is the Kumho Ecsta Sport 205/40R17 a Good Tire?

The Kumho Ecsta Sport 205/40R17 is a summer ultra high performance tire designed for compact sports cars and performance sedans. It delivers strong dry grip and responsive handling with adequate wet traction thanks to its performance-oriented compound and directional tread design. Ride comfort is firm with noticeable road noise due to the low-profile sidewall and performance focus. Tread life is moderate for its category, as the soft compound prioritizes grip over longevity. Rated Excellent by TireRack based on 8 consumer surveys, it excels in warm weather performance driving but is not winter-rated and may feel harsh for daily commuting. Currently priced from $150.8, it is available through major online tire retailers.
