Nothing but love for my Supremes,they handle like sport bike radials. Not sure how many miles I got out of my first set,my math says over 3k miles. This was on a 32lbs touring bike that also hauled groceries. Something did penetrate the rear,but only enough to nick the tube and cause a slow leak that I was able to ride home on. Many,many other scars from stuff that didn't get through,and I've never had to fix a flat on the roadside with them. Awsome in the rain,and the reflective sidewalls are a big plus. Totally worth what I paid for them,enough that I bought the second set to replace them.
