I think this is an important area of any concours event. Tires are one of the items that certainly fall into the "safety item" category. In a lot of concours competitions, items that are replaced due to safety concerns are not deducted for in judging. As long as the replacement part meets original specifications. Of course in this case this would mean replacing the tires with original sizes and specifications such as no white lettering and so forth. I think the correct Yokohama match is perfect or any other that meets the original size front and back. I don't think any tire manufacturer would tell you its safe to drive on twenty year old tires. No matter what the tread life they have left. Yes, I know some original NCT's still look new and the rubber is not cracked or worn. However tires do break down over time. I think a DeLorean Concours should look at safety items very closely. In my case for example I want my car to be as original or concours as possible. However when it comes to safety items I want to upgrade or replace where necessary to ensure the car is safe and if I want to drive from NJ to Cleveland for example I have no reservations about the car performing well without any unforeseen problems. On my car for example I have upgraded items that I believe we have learned over time are prone to problems. I have added a lockzilla, fanzilla, metal coolant bottle, and new Yokos to name a few. Also new window regulators and taillight circuit boards. My car was in like new condition when I bought it. In fact of all the items I mentioned that I replaced, I hadn't experienced problems with any of them before replacing them. However after studying the DML and researching the car as we all have, I learned the potential problems that might, and in fact, would likely occur. I wanted the car to as reliable as possible mechanically. However I want it to be stock as possible as well. I wouldn't change anything cosmetically on the car but that's my own preference and we each have our own taste. My NCT's had only 7000 miles on them when I took them off. The tread looked like new and they had no signs of dry rot or cracking. In fact they looked new. I have them stored in my garage. The ride was slightly harder but that is expected with a 20 year old tire as opposed to a new set. In any event I think items replaced for safety mechanically, which do not change the car cosmetically, should be allowed. I like the idea of being able to bring the original part to show you only changed the part for safety. An example would be to put on a metal coolant bottle but have the original with you for concours competition. Tires of course are different and should be excluded as long as they match original specs. No one should be expected to haul a set of original tired to a show. I would like to see an addendum to the concours handbook listing safety items that most, if not all members of the DeLorean community, would agree should be replaced or upgraded due to the fact that over time they have proven to be unsafe or unreliable. Just a few items to give an example in my opinion are: fan relay, lock module, coolant bottle. Also items such as tires that wear or break down over time. My two cents.
