It’s essentially a thermometer which measures the tire temperature deep Positive camber is defined as the tops of the wheels tipping away from the vehicle. Vehicles that specify high positive caster usually have a steering dampener attached to reduce any adverse effects. When cornering, the vehicle weight shift is met with a maximization of the tire contact patch on the outside front wheel that’s under maximum cornering load. Positive caster has the wheel of the vehicle in front of the upper pivot decreases the relative tire wear under these conditions. “Toe-in” means that the leading edge of the tires are turned Camber plays an important role on lateral forces provided by the tire.
