A Continental tire is an upright, external, mounted spare tire behind an automobile's trunk compartment. The term also describes a non-functional bulge that is stamped into the trunk lid or a cosmetic accessory to the rear of the car giving the impression of a spare tire mount.
The pre-mounted spare tire and wheel combination on early automobiles typically meant an external mounting. Early European sports cars had their spare tire attached on the back of the automobile since their trunk or storage space was often very small.
The development of the enclosed trunk on automobiles meant the spare tire could be placed out of sight, but this arrangement used up valuable space for carrying luggage. Edsel Ford had a special car built after returning from a trip to Europe that would have a "continental look" - including a spare tire mounted on the trunk. The 1939 Lincoln Continental's short trunk with its external rear spare tire mount became a distinctive design. While this was not the first car to either carry its spare above the rear bumper or integrated into the rear bodywork, it was the first to do it so elegantly and thus this feature became known as a "Continental tire" even if the design was found on other brands.
Similar spare tire placements added to more prosaic automobiles were also described as a "Continental kit", borrowing their name from the production Lincoln Continental.
There is a legend that Henry Ford II complained that the trunk of his personal Ford Thunderbird did not have room for a set of golf clubs without removing the spare tire. The 1956 Thunderbird had its spare tire mounted outside. However, adding weight behind the rear wheels was said to adversely affect steering and handling. For 1957 the Thunderbird's trunk was stretched 5 inches (127 mm) to allow the spare tire to migrate back inside, although the Continental mounting was still optional. This external spare wheel mount became a customizing aftermarket appearance accessory during the 1950s.
In the United States, the external Continental tire mounting was a factory option on various types of cars during the 1950s and early 1960s. On some models - such as on the Nash Metropolitan, Jeepster Commando, and Mercury Turnpike Cruiser - the Continental tire was a standard feature. Most often, the car's rear bumper was extended and the tire had a fabric or metal cover. The bracket for the spare wheel was designed to swing away for access to the trunk.
Contemporary examples of Continental kits are sometimes found on customized automobiles. It has become an accessory that typifies "the spirit" of the 1950s. Continental kits were also made popular by the pimpmobile craze of the 1970s, not to mention the Pimp My Ride show. Continental tires are known as 'fifth wheels' in hip hop slang.
Numerous compact sport utility vehicle (SUV) models of today have an exposed rear mounted spare tire. This is no longer described as a Continental tire. However, the historic Jeep DJ "Surrey Gala" with the fringed top, seats and Continental tire mount are of colorful vinyl coated fabrics with 'candy stripes' of pink, green or blue to match solid body colors.
