Would you trust 13 year old tires?

I drove a set of 4 tires on my 'Cuda over 25 years and sold them with the 14" Ralley wheels they were on with about half the tread still on them. No cracks. Garage kept car with very few annual miles. Tried to never get caught in the rain and it rains often in Seattle. ;-)
They were Riken Radials. Tires were put on the car in 1987 or 88.
This is right before putting on the 17" Year One Rallye Wheels in January 2014
Those poor little tires didn't stand a chance against the new 418...
