Not enough owner reviews yet to extract themes.

Tire B Kumho Ecsta PS71

The Kumho Ecsta PS71 is widely regarded as a high-value, mid-range performance tire that offers impressive wet and dry grip, often rivaling more expensive premium brands. While most users praise its handling and affordability, a subset of owners reports significant issues with road noise, inconsistent manufacturing quality, and occasional balancing difficulties.

Pros

  • Excellent wet and dry traction
  • High value-for-money proposition
  • Predictable handling and cornering feedback
  • Strong aquaplaning resistance

Cons

  • Reports of road noise and droning at highway speeds
  • Inconsistent manufacturing quality (balancing issues and 'egg-shaped' tires)
  • Soft sidewall construction leading to a 'floaty' or unstable feel for some drivers
  • Variable tread life depending on vehicle type and driving style

Observations

  • Users with high-torque RWD vehicles (e.g., BMW, Jaguar) generally report high satisfaction with grip levels, though some note faster rear-tire wear.
  • Owners of smaller, lighter vehicles (e.g., MX-5) occasionally report a 'floaty' sensation due to tread block movement, which can be unsettling during spirited driving.
  • Some users on larger rim sizes (19-20 inch) report increased road noise and sensitivity to road imperfections.

“Those are Kumho Ecsta PS71s, thread width is supposed to be 245mm, the actual one is hardly 235. How so?”
r/TyreReviews ·3 upvotes ·2026-03-08

“Between those I'd go with the Premiumcontact 7 or the ZE320 if you want to save some money. The continental seems to be serious competition for premium UHP tyres, afaik it gets similar results to the PS5 in tests. I wouldn't touch any of the sporty tyres mentioned, except for the PS71 which I still wouldn't take over the Continental.”

“I've had the PS71 several years ago - it was ok, nothing spectacular. They might have changed the compound now, so it may be better. Its a good tire, I don't remember any real weaknesses, it just never felt like "yeah, this sticks like glue to the road". Edit: I just remembered - it was mediocre in the city - when the tire was not warmed up, but I reckon this is shared between most sport tires with high speed rating. Once warmed up was good.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
