I agree with most of what Ken says but most Deloreans are not running on NCT's anymore. They did not wear all that well and as he said they weren't the best tire anyway at the time. My point in mentioning this about tires is that no matter what you do, age is catching up on the NCT's. Worse than that is how the dreaded P.O. (previous owner) took care of them. I mentioned on an earlier post how a local owner replaced the tires on his car and we found the inside of one was all chewed up inside from being driven on flat. The tire looked OK on the outside but it was an accident waiting to happen. As good as the NCT's were back in 1982 they are old technology now. At this point in time my best advice for anyone is to save the NCT's for a Concours. The car WILL drive much better with a set of new tires. If you do drive on the NCT's you will never know how much better the Delorean can be with a new set of tires. Ken is also correct that if this was a big problem we would have heard of more tire failures by now and we don't so I attribute that to the fact that most of the driven cars don't have NCT's and the ones that do aren't driven much.
