Found more or less what I was looking for in this video: youtube.com/watch?v=tsnYqCRWTbE . So, there is always some sliding present, even on dry roads. | |

The analagous situation is cornering, which uses many of the same mechanisms, and there, even at small slip angles, tire pressure and tire construction have a noticeable and measurable effect. So far as I know the grooves are there for wet weather and I suppose snow, but I've never been involved with them. | |

Do I understand correctly that when a car brakes on a dry or a wet road, and braking is well bellow the "Threshold braking" limit/skidding, the thread depth, air pressure or overall tire quality will not make a difference on breaking distance ? And thread is mostly needed to maintain contact (prevent skidding) in harsh conditions and probably give more kinetic friction if skidding happened? | |
