If you can peel rubber chunks off the sidewall with your fingers, it's probably unsafe. Also, if you are going to run old rubber, use them only on the rear tires. A front tire blowout is a lot less fun than a rear tire. Although, a rear tire blowout in a corner could put you upside down in a ditch. Run at your own risk.
