Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
Community opinion is split. Some owners praise the tire as quiet, predictable, good in winter, and a cheaper alternative to the Michelin CrossClimate 2. Others report fast or uneven wear, with lifespans of about 24k to 60k miles and some premature wear cases, and say the tire is lower-tier compared with premium all-weather options. Most posts are shoppers asking for opinions, and the tire is often chosen for its low price and 3PMSF rating.
“We're now 18 months later, and my Kumho Solus 4S HA32 235/45 R18 W (98) are ready to be replaced (a bit more life in the fronts, but the rears certainly - this is a RWD only Model 3 SR+ on 18" rims). The car is now at 48.5k miles, so it looks like I got about 24k miles out of them in that year-and-half. Sadly those exact Kumho tyres don't seem to be available anymore, and the alternative which comes up is Kumho Solus 4S HA32 235/45 R18 Y (98) which has a worse fuel efficiency (only C, rather than B rated). So while they are competitively priced (little changed), I'm looking at other brands.”
“Kumho HA32 fast wear Hey all, would just like to share my experience with the solus ha32 4 season by kumho. These tires were installed at 173,000km last September and currently have 188,000km… around 15,000km give or take 10,000 miles in all types of weather. They are nearing end of life already.. thoughts? Overall they do ok in the snow but arent amazing. Noise isnt horrible, but the wear holy man this is crazy. I had the front suspension replaced as well as an alignment on the day of tire installation. Read more”
“If you want a budget tire that’s great for winter, I’ve had great experience with the Kumho SOLUS 4S HA32 it’s a direct competitor to the Michelin CrossClimate 2 but it’s usually $ 50 to $ 80 less per tire.”

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.
