10 year old tires ok for highway driving?

be very careful--- I had old tires on my convert with great tread-- always garaged & one night -- it just popped the tread right off. I believe these were 8 + year old tires--- white letter-- cannot remeber the brand. On this site there is another member with similar situation that just happened to him. Putting around town -- maybe -- but hiway driving nope. Lawrence
