General Motors was coming out of the wire wheel era by 1936. This as well as wood spokes had been a standard with most cars and light trucks since the beginning at the turn of the century. The new stamped steel wheels on Chevrolet 1/2 tons were easier to produce, and was less susceptible to side damage on rough terrain or in an accident.
We find that both 17′ design 1/2 ton wheels were available in 1936, the transition year. In 1935 all 1/2 ton used wires and all 1937′s had stamped steel wheels.
The two attached photos are Chevrolet promotional pictures from 1936. These 1/2 tons are the same except for the wheels.
NOTE: GMC’s first entry into the 1/2 ton market was 1936. These used the new stamped steel artillery wheels like the later 1936 Chevrolet.
