Does anyone have a picture of the front of a non-lifted Xterra with the wheels turned?

Reason being I just noticed that when I am parked and the wheels are turned, they do not run parallel to each other. The passenger tire/wheel turns out a lot more than the drivers.

That's normal. The wheel on the inside of a turn should be turned more than the wheel on the outside of a turn because it cuts a tighter circle.

Thanks for the explanation.

It is known as Ackerman Steering.

Here's a very good explanation, even though it's aimed at R/C Cars...
