The track refers to the distance between the centerlines of the traces left by the wheels on the vehicle's supporting plane (usually the ground). If both ends of the axle are double wheels, the track is the distance between the two center planes of the double wheels. Generally speaking, the wider the track, the higher the driving comfort. The rear track specifically refers to the distance between the centerlines of the traces left by the rear wheels on the vehicle's supporting plane. The data of the front and rear tracks are designed by the manufacturer according to the vehicle's characteristics.
Generally speaking, the wider the track, the higher the driving comfort, and a wider track can provide better stability. When the vehicle is driven laterally, the outer wheels can provide better support. The vehicle's roll angle is smaller in the curve, and the limit of the outer wheels will occur later. In addition, the track also affects the vehicle's total width, total weight, and safety.
An increase in the front track will increase the vehicle's turning radius, so the steering angle of the front wheels of a vehicle with a large front track should also be increased accordingly to offset the adverse effect on the turning radius. Generally speaking, the wider the track, the more beneficial it is for the stability of handling, and it is also beneficial for the body styling and the spaciousness of the cabin. The lateral stability is better. However, a wider track usually increases the vehicle's total width and total weight, but the track should be adapted to the vehicle's width.
