Kumho Ecsta PS91 Summer Performance Tire
Unlock sharper turn-in and confident warm-weather grip with the Kumho Ecsta PS91. This max-performance summer tire suits enthusiasts and daily drivers who want a more connected, responsive feel from a sport sedan or coupe. Its summer-focused compound and tread pattern, tuned for high-speed stability and wet evacuation, deliver control and braking when the pavement heats up. If precise steering and balanced wet and dry traction are your priorities, the Ecsta PS91 brings track-inspired capability to everyday driving.
Key Features and Technology
The Ecsta PS91 is tuned for quick, confidence-inspiring handling with a warm-weather compound and large outer shoulder blocks that resist squirm in hard cornering. Steering response and feedback stay precise, while wide circumferential grooves and lateral channels evacuate water to maintain traction in summer rain. A reinforced construction supports stability at speed, and a solid center rib steadies on-center feel. As a dedicated summer tire, it favors dry grip and wet control over cold-weather versatility.
Wet and Dry Performance, Noise, and Comfort
On dry pavement, the Ecsta PS91's stiff shoulders and summer compound deliver quick turn-in and strong mid-corner stability. Braking stays reassuring in warm temperatures, and the solid center rib helps the car track cleanly during lane changes. In the wet, wide channels and open lateral grooves clear standing water to reduce hydroplaning and preserve grip. Ride quality is firmly controlled for the max-performance class, and in cold conditions the compound can harden below about 45 F (7 C), which reduces traction and increases wear.
Sizes and Fitment Guide
The Ecsta PS91 is commonly fitted to sport coupes and sedans in sizes such as 235/35R19, 245/40R18, and 275/40R20, with many options carrying W, Y, or (Y) speed ratings. Match tire size, load index, and speed rating to the vehicle's OE specifications on the driver door-jamb label. Staggered setups are common on performance cars, so keep front and rear overall diameters within the manufacturer's tolerance. Follow the sidewall mounting instructions and maintain proper alignment and rotation intervals to promote even wear and consistent handling.
Pricing and Availability
Pricing for the Kumho Ecsta PS91 varies by size, load and speed rating, and region. Some sizes may have limited stock or seasonal availability, so check current inventory before planning a full set. Watch for four-tire bundle savings, and include mounting, balancing, TPMS service, and alignment to calculate a true installed price. If your size is unavailable, our team can recommend close alternatives with a similar performance focus, with fast shipping or in-store installation at participating locations.
Reviews and Owner Feedback
Owners often praise the Ecsta PS91 for sharp steering and a planted feel during spirited driving, with strong dry grip and stable highway manners. Wet-road confidence is solid for a dedicated summer tire when tread depth is healthy. Trade-offs include a firmer ride, shorter tread life, and the need for seasonal changeovers in cold climates. Proper inflation, alignment, and timely rotations have a big effect on longevity.
Comparison: Ecsta PS91 vs Alternatives
The PS91 is aimed at higher outright performance, with a summer compound and tread tune that sharpen steering and high-speed stability. The PS71 leans more toward everyday comfort and balanced wet performance in the ultra-high-performance category. If road feel and cornering response in warm weather are your top goals, choose the PS91. If you prefer a smoother ride and broader day-to-day manners at the expense of ultimate precision, the PS71 is the better fit.
Kumho Ecsta PS91 vs Michelin Pilot Sport 4/4S
Michelin's Pilot Sport 4 and 4S are frequent benchmarks for wet grip, refinement, and size coverage, typically at a higher price. The Ecsta PS91 concentrates on sharp handling and strong warm-weather traction at a more accessible cost in many sizes. Drivers prioritizing ultimate wet traction and ride polish may prefer the Pilot Sport family, while value-minded shoppers who want precise steering and an engaging feel often consider the PS91. Real-world results vary by vehicle, alignment, and driving style, so review independent tests and recent owner feedback for your exact size.
