> Wheels work so that from the point of view of the wheel the asphalt is still In order to create a longitudinal force, the tire must have non-zero slippage. It’s not large (for typical mild driving), but it’s not zero if you’re using the tire to accelerate or decelerate the car. Max acceleration forces are found around 10% slip ratio. http://www.insideracingtechnology.com/Resources/bhvrdrvbrkslip.gif http://www.insideracingtechnology.com/Resources/bhvrdrvbrksl...
