Tires can swivel left or right, rather than aligning straight-ahead {toe}|. Toe is in or out. It causes stability because, during turns or bumps, tires tend to return to straight-ahead position. At higher speeds, toe becomes slightly more out, so starting slightly in is better. Out is only for front tire center offset or special wheel bearings. Rear tires are neither in nor out, because in or out causes instability and rapid tire wear.
