What is the problem that there are no full bicycle tires?
And still wheels with spokes instead of a large disc or two
placed against each other with different circles drilled into it?
That makes me wonder why road bikes need such narrow tires
because they leak more quickly because they have the same force on one
have a smaller contact area.
Or would the deformation energy differ so much?
Answer
The first wheels had no tires and no suspension. They drove uncomfortably because they directly and unmercifully pass on all the bumps of the road. Solutions that improved comfort were sequentially:
– large wheels: these mean the unevenness somewhat.
– suspension between the wheel axle and the vehicle, as you still have in motorized vehicles.
– very soon rubber tires also appeared on the market. The original rubber tires were full. Better than nothing, but still not comfortable.
– in 1847 mr. Tomson (http://en.wikipedia.org/wiki/Robert_William_Thomson) out of the pneumatic tire precisely with the intention of taking advantage of [een gewichtsloze] to build suspension into the wheel.
Tires of a racing bike are thin to have as little friction as possible. To prevent them from collapsing under the rider’s weight, they must be inflated to a higher pressure than a fat tire. They stand up harder, and are therefore more susceptible to band breakage.
