In addition to Jimmy’s comments above; in the late 1980’s, Garry Hall paid to have Campagnolo (by then Technomagnesio) restore the tooling for the 15” x 10” wheels that are used on the rear of a regular body Pantera. As part of the deal, Garry imported a container load of these wheels. I believe he sold all of them and I think it’s safe to say, the majority wound up with 285/50-15 P7’s mounted on them. Pirelli certainly knows how many they sold during the decade they were available. Gauging potential demand should be fairly easy and I’m sure it’s far more than 200 tires!
