Promotional Vehicles Part 4: The Most Extravagant Creations

One of the most incredible aspects of the automotive world is that it knows how to amaze every time. We have discovered together in previous episodes, truly amazing promotional vehicles, but this week we have decided to raise the bar by proposing the most extravagant of all eras.
In 1929, Goodyear developed a new low-pressure tyre called the AirWheel, designed for large aircraft. The news was so important that the company decided to take it around the United States, indirectly publicising tyres for road use. The vehicle in question was a Buick Sedan whose chassis had been stretched and modified with a bus-like body with a full-sized AirWheel tyre added to the rear! Spectacle.
