Some people use superglue or Shoe Goo to heal tread cuts. Others just let them go. You don't have to worry unless there is a bulge in the tire, which indicates some cuts in the casing threads. At that point you could boot the tire to make it last. Some throw out tires based on appearance. Me, I wait until I start to see some casing threads showing through the tread rubber.Psychler said:So, I have Mich Pro Race 2 tires... I see small cuts on the 'tread' area...about 1/4" long. Just a few of them. When do I change tires? When do cuts become something to be concerned about? What's the 'rule'???
