I am quite sure most on this List have read about tire safety but here is an interesting article that perhaps explains in a little more details about tire safety.
How Old - and Dangerous - Are Your Tires? - Edmunds<https://www.edmunds.com/car-care/how-old-and-dangerous-are-your-tires.html>
For years people have relied on a tire's tread depth to determine its condition. But tire age is just as important.

With all due respect to Gary, and he has done an enormous amount of research on the subject of tires, the Austin-Healey Concours Registry Committee is considering changing its Policies and Guidelines as Gary has stated, BUT with a 15 year cut off on tires, not 10 as he has stated.
We expect to finalize this change in the next couple days and I will post to the List the new policy.

One comment suggested misreading -- In the new standards, we accept both bias-ply and radial tires for concours, without giving either one point differences, without deduction as long as they are the correct original narrow-width thread with tall sidewall size for the car -- 5.90x15 and 165x15. We have a standard deduction for any other tire size, we deduct for a non-matching spare, and we do not inspect cars with tires over 10 years old.
The reasoning is that safety is paramount -- old tires can delaminate without warning, regardless of appearance, with life-threatening consequences -- and beyond that we prefer to see concours cars with appearance as close to original as possible with any part where the original brand is no longer available, and we do believe that all new tires from standard sources in the original sizes are safe and reliable for use in long-distance touring at highway speeds.
