This would be more properly referred to as load transfer, [1] [3] and that is the expression used in the motorcycle industry, [4] [5] while weight transfer on motorcycles, to a lesser extent on automobiles, and cargo movement on either is due to a change in the CoM location relative to the wheels. This article uses this latter pair of definitions.
Body roll allows a vehicle’s centre of mass to move towards the outside of the turn, increasing the load transfer to the outside wheels. This can cause understeer or oversteer to occur more easily than if body roll was not a factor. Body roll can also be uncomfortable for passengers and cause damage to cargo.
The first is to reduce body lean. This is dependent on the total roll stiffness of the vehicle. Increasing this stiffness does not change the steady state total load (weight) transfer from the inside wheels to the outside, it only reduces body lean. The total lateral load transfer is determined by the center of gravity height and track width.
Excessive load transfer – On any vehicle that is cornering, the outside wheels are more heavily loaded than the inside due to the CG being above the ground. Total weight transfer (sum of front and back), in steady cornering, is determined by the ratio of the height of a car's center of gravity to its axle track .
This maneuver (known in racing as a Scandinavian flick) increases the load transfer to the outer wheels. Classic bootleg turns can be performed only on cars with a manual transmission and are most easily accomplished with a rear-wheel-drive car, as the spinning back wheels aid in the turn.
Weight transfer – Wheel – In its primitive form, a wheel is a circular block of a hard and durable material at whose center has been bored a hole through which is placed an axle bearing about which the wheel rotates when torque is applied to the wheel about its axis. The wheel and axle assembly can be considered one of the six simple machines.

Weight transfer during cornering, acceleration, or braking is usually calculated per individual wheel, and compared with the static weights for the same wheels. The total amount of weight transfer is only affected by four factors: the distance between wheel centers (wheelbase in the case of braking, or track width in the case of cornering), the ...
