    Regardless of the mileage...

    When the tread is gone, replace them. And yes the noise increases when the tread lowers, and its very noticable now; for me at least.

    My last set lasted 20k. If you off road them at all they come apart. My gen 1 had better life 37k on the originals. Gen 2 just eats them.
