I had my first accident two days ago (minimal injuries so don't worry about that), and it's got me thinking about a lot of different aspects to driving and cars, such as braking. Had my braking been even slightly less effective, it would have been a very different story. This lead me to do research on cars with good 60 mph - 0 mph distances, but in doing so someone claimed that it was effectively just a tire comparison. So is this true? Assuming brake pads which are able to lock up the tires and ABS, and ignoring downforce, is it all just down to the tires? To specify the scenario, let's say i

Preface I ended up doing a fair bit of thinking and research on this, so I figure I may as well write up what I found. Thanks all those who responded, particularly BobCross. In the end though, I wanted an answer that went beyond calling a car a mystery box on balloons - I asked this question because I actually want to understand it. Intro - Tires Given the situation of a car that has sufficient braking power to lock the wheels and ignoring aero, tires are the final determinate of stopping power. Having said that, there's a lot of factors that affect how well those tires grip the ground. Weight of a Car The stopping power of a car is friction. With proper ABS, the wheels are rolling in contact with the road, so we're primarily talking about static friction. Some slip occurs because of the softness of tires, but it's pretty close to static. Basic physics tells us that friction is equal to the normal force times the coefficient of friction, i.e: Ff = µ * Fn where Ff is the force of fricti
