Would you trust 13 year old tires?

I'm running 10 year old reproduction biasply red lines and they are much, much worse than they were even 5 years ago. Absolutely zero traction with the slightest bit of moisture on the road.

I only use them for slow town cruising. They still look much as they did when I got them but they are rock hard.

I believe that much over 5 years and you are on borrowed time.

I'm going with a modern radial next.
