Explantion: Coasting is a bad practice that happens when a driver allows a vehicle to move by its own momentum (or by gravity — for example, down a hill) with the engine disengaged. This can be done in two ways: 1. By putting the car into neutral gear while moving; or 2. By keeping the clutch pedal pressed down to disengage the selected gear. If a vehicle is coasting, the driver has much less control, so you should never coast. However, it has no effect on tyres.
