7-10 years for an average street tire. That being said if a tire is 7-8 tears old and you are driving on the highway for long enough for them to get hot,that is when they are more likely to fail.

A hot rod or performance application is a little different to me.Is it worth the risk? Can you afford to lose your car or life because your tires look fine?

Putting around town is one thing. High speed or throwing one into a corner at speed on an old tire is asking for trouble.
