I’ve always noticed how race car tires have a very different attitude than street car tires. They are often wider and sit under beautiful fender flares. But they also seem to have a bit more tilt in them where the bottom of the tire sticks out further than the top. I’ve lately discovered this to be called “negative camber”. Camber is the tilt of the wheel around an imaginary axis line that would run either between the two front wheel centers or the rear wheel centers. When the top of the wheel moves in toward the center line of the car and the bottoms move outward, that is “negative camber”. The opposite is positive camber.
