All of the non special government contract 4WD wagons left the factory with 15 inch wheels and without hubcaps including the Mavericks. Only the 2WD wagons came with hub caps. The dealers did carry Willys authorized accessory wheel covers (not hubcaps) that were manufactured by Cutlass. They looked like giant size baby moon wheel covers. The dealers also offered 16 inch wheels as an accessory and were required to paint them the same color as the vehicle or the bottom color if the wagon had the deluxe 2 tone paint job. According to a old service bulletin I read, Willys dropped the requirement to repaint them sometime in the late 1950s. I assume they were white wheels.
