If you don't have the toe set right the steering wheel will be off. The tires take care of themselves, if toe is off they find their middle ground and roll as straight as they can down the road. tracking, or dogtracking, is when the front end isnt aligned properly with the rear tires/thrust line of the vehicle. So basically if you mess that up your front tires are lined perfectly, the steering wheel is straight, everything is right except your front tires are offset a bit one way or the other and it looks like a dog running, its butt is trying to catch the front
