Is the front wheel of the van inside or outside?
The toe-in of the front wheel is an inner figure. The inner figure of eight means that the top of the carriage wheel inclines inward, and the outer figure of eight means that the top of the carriage wheel inclines outward. Because the front wheels are inclined outward, the left and right wheels often act on the roll thrust corresponding to the camber angle in the opposite direction, which increases tire wear. In order to avoid this, it is necessary to eliminate this rolling thrust.
