If springs were fitted to the ridges in the tire of a cycle, would it make the cycle ride more 'easier' (considering only flat terrain)?

enter image description here

Kind of like in the above meme? What would be the favorable range for the springs' coefficient?

It would make it more difficult as the springs will slide on the surface as they have very small contact with the surface and also low friction coefficient

  • $\begingroup$ Wouldn't there also be an equal torque in the direction of rotation (from springs which are leaving contact with the ground)? The reverse and forward torques would cancel out (mostly). I don't think the flat tyre is acting like a spring. $\endgroup$ Nov 25, 2020 at 16:34
  • $\begingroup$ @sammygerbil yes there would be but not equal think of the case of flat tyre then it should also have a torque and its antitorque $\endgroup$

  • $\begingroup$ then why is it difficult in that case while driving $\endgroup$

  • $\begingroup$ Tyres are very spring-like when fully inflated but much less so when they are under inflated or flat. In the former case the deformation is small, elastic and symmetrical so that forward and reverse torques balance. In the latter case the deformation is large so the non-elastic loss (hysteresis) is greater; and the deformation is not symmetrical, more rubber is squeezed into the leading edge of the wheel so the forward and reverse torques are very different. $\endgroup$ Nov 25, 2020 at 17:13
  • $\begingroup$ @sammygerbil I have made another thought on it please check it out $\endgroup$
