I've got right at 15k miles on The Blueberry. I've rotated the tars twice now. They actually look like they'll go at least 30k miles at least. They're not showing much wear. My plan is to go back with Vredestein Quatrac 5's when the time comes. Those tires will be $500 a tire by that time, at the current rate we're going.
I worked 7 years for Hyundai-Kia and very closely with MANY Korean vendors. I will not buy Korean tires, ever, if I can help it. But more power to ya, if you guys choose to do so. I'm sure that they're not ALL bad. But I was left with a very bad taste in my mouth in regards to Korean automotive products (after having worked for Toyota).
