I have two Sumic with around 30,000 miles on my Focus. The car ruined the other two. Sumitomo is made by the same rubber co as Sumic. I didn't like them too much when they were new because they were a little noisy. But now that they're worn almost down to the wear bars I think they're OK.
When a previous set of Kumhos were worn down to this point they rode like wooden wheels.
