DRIVELINE WINDUP; "You will recall that at the beginning of this section, we mentioned that we had made sure that all four tires on our truck were the same size, were worn the same amount, were inflated to the specified pressure and were subjected to reasonable loading. Avoiding driveline windup was the reason for this. Figure 18A shows that tires of even slightly different size roll different distances every revolution. Figure 18B shows that the same effect is true for tires that are the same size but inflated or loaded differently. Operating a 4 x 4 in 4WD with tires of different size or inflation will produce driveline windup, even when driving straight ahead! If the vehicle is being driven in 4WD on dry, hard pavement, the driver will notice drag and may experience the hop, skip, bounce effect as the front or rear wheels release the windup..."
