8. A Veterinarian "Shoes" a Horseless
Carriage
To compare the relative speeds of these two
tires, the air disc one and the old solid tire, Dunlop rolled them
across his yard. The new air tire went the whole length of the yard and
bounced off the wall at the end. The solid tire did not go nearly as
far.
And so from that time on, his son Johnny would
have nothing but the new air tires on his tricycle "because he could
beat the bigger boys." But Dunlop then did not have the slightest
conception of the automobile. He didn't rate the pneumatic tire as a
scientific invention, but only as something to please a small boy.
In England at that time, bicycle racing had
become one of the most popular sports. Everyone was interested in
anything that would increase the rider's speed. As an
experiment, Dunlop equipped one of the new "Safety" bicycles with
his pneumatic tires, and William Hume, who was not one of the best
riders, defeated all the solid-tired competitors in his first
race. Among the defeated riders was Harvey DuCros. Arthur DuCros,
learning of his brother's defeat, investigated the new tires and had
them put on their new "Safety" bicycles. The following year, he
and Harvey won all of the English and French races on their Dunlop
tires.
But people were not exactly convinced, so when
news about these revolutionary tires began to travel, the "Irish
Cyclist," a trade journal, made these sarcastic comments: "Pneumatic?
Something to do with air, isn't it? Quite right, too, we like to see
new ideas well ventilated." But Dunlop did not let such criticism
or the more practical difficulties discourage him. In 1890, through the
help of the DuCros, the Pneumatic Tyre Company was formed and the
new tires soon became standard on nearly all English and
American bicycles.
