Can't comment on the Dunlops although in speaking with folks I know in the business the Kumho Ku25 are great for the first year and then they get hard and lose a tremendous amount of grib in 2nd and subsequent years.... Heard this from a few folks. I was considering them, thats why I was inquiring. I went with the Falken 912s and I'm very happy!!!
