Is there such a thing as too old?

I would not trust them if the rubber is starting to harden or you have a slow leak, due to age cracking.

Trusting old tires on a performance car leads to several possible outcomes.

1) A catastrophic blow out at higher speeds that sends you careening all over the road and may cost you new rims or worse because the old tires tend to disintegrate very quickly when they let go leaving you riding on the rims.

2) If you don't have a spare tire, just the goop and compressor then the old tire will likely leave you stranded at the side of the road as an old tire tends to self destruct when run flat and no amount of goop will be able to seal the resulting leaks.

Sure you can gamble and save a few bucks, but if the gamble does not work out it may cost you a lot more than 4 new tires and a comfortable wait in a Tire shop waiting room reading a magazine, drinking a coffee.
