I had them on a car from the factory rotated every 5000 miles and got 82000 miles on a set.

Thanks for all the comments.
I'm not considering Kumho tires because they are cheap(low cost) They are only about $25 per tire less than other brands.
Before I retired I worked for a Company that had hundreds of Armored vehicles, many rode on Kumho tires, I never remember any tire problems. I remember first seeing the name on the sidewall and laughed at the name figuring the Company was cheaping out buying the cheapest tires. I asked the mechanic about them and he surprised me with his glowing approval of the brand.
I ask about Kumho because I was curious about there non commercial tire offerings.

I have class D Kumho on my boat trailer. Best trailer tire I've ever had period.

I had a set on my WRX and they were a good (not great)performance all season tire. I replaced them because I wanted something more performance oriented. If they met the application I was looking at I would use them again.
