The cast of the tire print was identified as being on the left front of the defendant's station wagon. The tread shown is that of a snow tire. Snow tires were not mounted on the front of

Hamilton Burger (William Talman) has the tire iron as evidence. Perry Mason (Raymond Burr) jumps up and tells the judge that the tire iron can't be used unless it's properly introduced in court as evidence. Hamilton tells him that it will be.
