I've run 120s a lot, I love the width, the handling and the fat float you get....and I have noticed side cleat loss before...but currently I noticed its all on the chain side. My chain (O-ring and new) is adjusted to right in the middle of the factory spec and when I push it towards the tire it actually does hit the side cleats! Is this true? Am I really ruining my tire? Has anyone else seen this before? I guess I got to go back to 110s?
