For a smoother, safer drive you car needs to be balanced.
While the car is fully balanced, you have even weight distribution across the whole car.
The ONLY items keeping you car in contact with the road are your tyres, therefore you want an even amount of traction from all of them at the same time.
The second you start losing traction your risk of losing control of the car becomes greater.
This in turn reduces the level of traction to the road at the front wheels
This lightens the rear of the car and gives you less traction at the rear.
This in turn reduces traction from the opposite side of the car
You only have 4 tyres, and the less traction you have to the road the bigger the chance of losing control of your car
By ensuring that you carrying out any necessary braking BEFORE a bend, to a speed suitable for the tightness of the bend you will have more traction.
By ensuring you do not accelerate heavily when moving off, you will have more traction.
By not braking heavily in any situation, you will have more traction.
