I think these have a treadwear of 30. That's pretty low. The Kumho Ecsta version that I see most people run are the XS summer version that have a treadwear of 180 and a lot more size options. The XS version has gotten very good reviews and done well in comparison tests, but if you're running some events that have a minimum treadwear limit of 200, you're outta luck.
