Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Eagle F1 Supercar

Pros

  • Excellent dry grip and handling performance for spirited driving and road course use
  • Ideal OEM replacement option maintaining original factory specifications for vehicles like the Chevrolet Corvette
  • Good resistance to hydroplaning in wide sizes compared to some competing brands

Cons

  • Rapid tread wear and short overall lifespan, with some sets lasting only 8,000 to 13,000 miles
  • Noticeable drop-off in dry traction and increased wheel spin as the tread wears down
  • Poor grip and traction in wet weather and cool temperatures

Tire B Ecsta PS91

Pros

  • Exceptional dry and wet grip providing high confidence during spirited driving
  • Significantly more affordable than premium flagship alternatives while offering comparable performance
  • Stiff sidewalls enhance steering response, cornering stability, and feedback

Cons

  • Accelerated tread wear and shorter lifespan, particularly with aggressive driving or on heavier vehicles
  • Stiff sidewalls result in a firmer, less comfortable ride that transmits road imperfections
  • Tendency to tramline or follow road grooves on straight highways

Tire B

Kumho Ecsta PS91

Mixed

The Kumho Ecsta PS91 is widely praised as an affordable, budget-friendly summer tire with attractive styling and respectable wet or daily street performance compared to pricier rivals like Michelin. However, several users express frustration with poor tread life, rapid wear, and insufficient grip or heat endurance under hard driving and track conditions. Others also note issues with sketchy handling, flat-spotting, or vibration when cold.

“275/40 Square Can Fit on a Sedan Shout out to TireRack for having great information on actual tire size. Ecsta PS91 265/40 and ExtremeContact 275/40 has a tread width and section width difference of 0.1” and 0.2” respectively. Tires fit just about perfect. No rubbing so far, and don’t expect it to rub bc of the relatively minimal width change Really goes to show that tire brand matters for fitment Read more”

“90% used Michelin super sports or New Kumho ecsta ps91. I am juggling between either getting a set of used 90% tread Michelin pss or 4s... or getting some new kumho ecsta ps91s. I’ve always thought Michelin had the best ride and profile appearance even in a high end sport tire but of course the price. If I go used they are about the same price as a set of new kumho. I have never tried the ps91 but they look like Michelin’s even the recessed rim guard looks similar and many reviews say performance and ride is similar.”

“Iv gone threw so many tires and just a heads up... I will never get any other tire for the street other than a pss. smooth as silk all the way up to 160mph and redic grip in the corners for a street tire”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
