KITTs wheels are probably one of the top 5 most important things for a Knight Rider replica. In the series, KITT had 15 turbo-cast aluminum rims and bowling ball hubcaps.
In 1982-84 these wheels were optional on Firebirds and Trans Ams. They were also available in a 14 size and sometimes painted gold. According to the supplier Knight Rider Parts, about 36,000 cars came with any type of these rims. They are not easy to find, and very valuable to anyone who knows it.
