Take a look at the McCormick-Deering tractor - the gray one with the
red wheels. The teeth on the rear wheels are called lugs and were
needed to get traction working in the fields. By the 1950s most roads
were paved, but some farmers still had the old steel wheeled tractors
which were then banned from the roads so they didn't tear up the
pavement.
I see...
Somewhat like winter tyres with spikes which damaged the roads and
became dangerous projectiles, so they were eventually banned in most of
Europe.
