Prior to the 1960’s, trucks were used as work vehicles. On Friday nights, most were parked for the weekend and the family sedan was the transportation vehicle.
It was a conservative era when you bought only basic necessities. A $5.00 grocery purchase was more than most could carry. Finding white wall tires on a truck (even a car) would have been a rare sight, indeed. Very few cars, except for most luxurious models, would have had white walls even as an option. It should be remembered, that most roads, except highways and those in the main part of town were gravel, dirt, or sprayed annually with tar.
Of course, a dealer would have been happy to install aftermarket white wall tires, if the customer made a specific request. For a price, the dealer would provide any option to keep a satisfied customer and make a few dollars.
On GM trucks, white walls became a factory option in mid-1955, partially because of the introduction of the Chevrolet Cameo and GMC Suburban carrier and also due to more roads becoming paved. These very deluxe pickups, as well as several of the other well appointed 1/2 tons justified a white wall tire for those wanting it all!
Almost none of these deluxe models would have been given their second set of white wall tires. By then, the pickup was older and being used more as a hauler, not for appearance.
