I have a Kumho Ecowing ES01, mainly because it was in stock at the local tyre dealer and has fairly a symmetrical tread. It has lasted better than the original Yokohama, it may be my heavy right foot but that was worn out after about 7,000 miles, the Kumho has done over 8,000 and still has some life yet. It seems quite a good tyre, particularly in the wet, as I found out at Grindelwald this year wink.
