What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Kumho Crugen HP71

Mixed

Community sentiment for the Kumho Crugen HP71 (and its EV variant) is mixed, with owners praising its affordability, comfortable ride, and quiet performance on many vehicles. However, a significant number of drivers report disappointingly rapid tread wear—particularly on heavy electric vehicles—as well as occasional noise on coarse surfaces and internal acoustic foam detachment issues.

“Bought a set of Kumho tires to replace the OE Michelins on the wife's Ford Edge. The Michelins have barely 35K and aren't going to pass the NC safety check. For being a top tier tire they were wildly mediocre. I've has several sets of Kumho and they are better than average and not too expensive. I bought four of these. Anybody have experience with Kumhos? Kumho​ Crugen HP71​ 245 /60 R18 105V SL BSW​”

“2023 ID4 AWD Pro S Kumho Crugen EV HP71 I replaced the original worn down (and one with a sidewall bump) Pirellis at 33k with the EV version (badges on the sidewall) of the HP71 (direct from dealer). They're more expensive than the non-EV versions and have a lower warranty. So far they're impressive: ride is softer/smoother, quieter, deep treads. Hard to tell if efficiency changed with the winter weather, but we were getting 3mi/kWh on a 34 degree day.”

“That is a crazy good price - The TA91 is low $200s wholesale! (Tire shop pricing). And $279.30 retail. (Tire Rack) Grab them while you can. Sometimes Wal Mart beats any price I can get when they're blowing out a specific tire. FWIW we run the Kumho HP71 EV (OE tire) on our EV9 and it's a super quiet tire. I bought it again for the Spring now that the car is actually aligned and won't burn through them.”

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.
