In concours safety is not the primary issue, origionality and authenticity is. If safety was important then why are the rules looking for the origional fan circuit breakers, door module, fan fail relay, plastic coolant bottle and on and on. Some cars have burnt to death because of some of these "origional" parts. Tires should be the least of your safety concerns. I know of no posts to this list or any owner complaints because their 20 year old NCT's failed them a la firestone-bridgestone. If ANYONE can say that they had an NCT tire fail them please post to the list.(Not just a flat or hitting a curb). As far as tires in a concours with all things being equal the car with the NCT's should get more points.In some concours for other makes if you have the "recalled" rims on your car you get more points and it is really hard to get those rims and they are EXPENSIVE, let safety be dammed. In other concours there are no point deductions for safety related items such as seat belts, safety glass, or turn signals. This all comes down to "He who has the GOLD writes the rules". If you don't agree with the rules as they exist either accept them the way they are or if enough people care then we can change them. I for one would like to see more standardization with other associations like the AACA so that we will be able to compete in their concours without rebuilding the car or comprimising safety.
