Architect Bob Berryman bought a late model car from Fred's Ford dealership. Three months after he bought the car, he had to replace two of tires since he ran over nails at one of his construction sites. Fred's Ford replaced two of tires, one of which was defective. The defective tire blew out while Bob was driving and caused the accident in which he was injured. Should Bob file the lawsuit using the theory of the negligence or strict liability? What are the components that Bob would require to recognize to make the determination?
