Terrible tire, terrible customer service. I had a tire that was less than a year old with fewer than 25K miles have a split running along the thread.
I contacted Kumho and they acted like they wanted to help, but then quickly just stopped responding. Looking on their facebook page, I see that this is not a unique occurrence.
Spend a few dollars more and avoid at all costs!
I've only been running these for about a month so I don't have a clear idea of how they'll wear over time but on all other points: TOP MARKS.
These tires are fantastic. They handle beautifully, sticking to snow, ice and bare pavement very competently.
While I bought these tires for their value pricing and excellent reviews, not noise level, I'm pleasantly surprised by how quiet they are.
