I have heard that turning the front wheels while the vehicle is not moving will not effect the life of the tires that much but will decrease the life of all the components in the steering system. Is this so?
Yes, the amount of force needed to turn the wheels when the vehicle is stationary is very great, and just crawling a little can reduce the wear on the steering rack, power steering pump, and various bushings in the front end, and make those components last much longer!
