Suppose, the wheels of a car were to be replaced with solid concrete wheels, which do not deform,flex, etc. Would the car not be able to accelerate, take corners, etc ?

I do not understand why is it necessary for tires to develop slip for them to be able to move the car.

  • $\begingroup$ If so, when what's all the fuss about slip angles,slip Ratio, etc in the automotive world? There must be some problem with non-stretchable wheels. $\endgroup$

  • $\begingroup$ Something should flex out the disturbances from the ground, the sooner the better. $\endgroup$ Sep 19, 2017 at 12:38
  • $\begingroup$ I am guessing that what you really want to ask is "what if the wheels had infinite friction coefficient" in which case yes, you can never turn a corner because the wheels can never slip-twist with respect to the ground. You need either to deform the tire or allow breaking traction. $\endgroup$ Sep 19, 2017 at 13:24
