Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Crugen HP71
Pros
- Strong value: frequently described as much cheaper than Michelin, Pirelli or Bridgestone alternatives while not feeling like a budget tire.
- Good wet and heavy-rain traction, with some reports of confident light-snow performance.
- Quiet, smooth ride reported by many owners, often as an improvement over the stock tires (Bridgestone Dueler, Pirelli, Hankook).
Cons
- Premature or uneven tread wear is the most common complaint, with reports of tires worn out at roughly 15,000 to 27,000 miles or within 1.5 years, far below the 65,000-mile rating.
- Road and highway noise, including howling that develops with mileage, reported by several owners.
- Vibration and difficulty keeping the tires balanced, in some cases even after repeated balancing and rotations.
Tire B N'Fera RU1
Pros
- Exceptional value for money compared to premium tier brands
- High level of ride comfort and impact absorption over rough roads
- Low road noise and quiet highway cruising
Cons
- Faster-than-expected tread wear or chipping reported by some users
- Softer sidewalls can lead to reduced steering feedback and vague high-speed handling
- Mixed performance in colder temperatures or under hard acceleration

Tire A
Mixed
Kumho Crugen HP71
Community opinions on the Kumho Crugen HP71 (including EV variants) are generally mixed, primarily leaning on price and initial comfort versus longevity. Many users appreciate the affordable pricing, quiet/smooth ride, and good handling, but a significant number report faster-than-expected tread wear and occasional issues with foam lining separation or durability on heavier vehicles.

“Kumho Crugen HP71 235/50R19XL 103V BSW ($132.44/each) Total: $264.88 Kumho Crugen EV HP71 255/45R19XL 104V BSW ($287.70/each Gigatires about a month ago I feel like they're just as good as the Continentals that came with the car It's crazy that these EVS have different size tires front and rear, prevents rotating tires for even wear. It's also surprising that the cost difference from the front the rear was so much different. It was also like that with numerous other manufacturers. I also drive about 24,000 mi a year, so we'll see if they hold up.”

“I need a new tire, right? 215/55R18 Kumho Crugen HP71 tire showing cords on the outer sidewall. I need a new tire, right? Edit: I’m thinking about replacing just this one tire, 2023 CX-30 AWD. Tires were new Oct 2025 and have 7mm tread depth left. According to the spec sheet, this new tire would have 7.9mm of depth. Can I get away with one tire? Edit 2: Existing vs new tires would have ~1mm of difference in tread depth Read more”

“How many miles do you guys get on tires? I had a blowout back in June, and decided to just buy a full set. The shop had a promo on these KumHo Crugen HP71 tires, which had a 65,000 mile warranty. 3 months and 12,000 miles later, my tread is completely gone. I got some Michelins and was credited 185 bucks per tire, but this seems insanely low mileage to wear out the tread completely. I know the added weight and torque of an EV somewhat lowers the lifespan of tires, but even if I was driving like a demon, I don't think 12,000 miles should be anywhere near the lifespan of a reputable brand.”

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.
