Trackergd - Taking a look at the bias ply scenario LE would have had a fairly accurate depiction on the width of the vehicle based on the remnants of the prints. One of the cars LE was looking for was an AMC Pacer or Gremlin. Both compacts would be about the same weight as a Volkswagen Beetle and were available from the factory with bias plys.

The distance between centers for the tires would be easy to determine, which of thousands of vehicles...not so much. Each manufacturer tends to use the same platform (frame and drive train) for more than one badge brand and year. They can get a general idea, but as I noted before, this type of forensics was in its infancy and the FBI was still gathering data that now is just a keystroke away for them. The bias ply tires would have been a better indicator. After market or new on the vehicle from the factory. Wear and objects stuck in the tire would register in the print. Brand new tires would leave a very sharp impression and the sprue's from the molding process would be evident. I doubt SCSD would have had the resources to go chasing all this information and doing the research. Jacobs last print and the tire print are in softer ground...the layer of dust that forms on the surface of the gravel and dirt road, and in the older ruts.
