Default Normal? Front Tires tilting when turned?

Don't know how else to ask this, and not sure if my pics are clear... but is it normal for the wheels to tilt to the outer edge of the tire when turned?

I think first pic does better than the second at showing what I mean...





Thanks!

Yes it's very normal. When you turn, the vehicle tends to lean away from the direction of the turn. The tilted wheel allows the tires to create a great contact patch to the road under these conditions. Your car is 100% a-okay!

I remember worrying about this at first too, but it's totally normal.

If he's ever owned a bicycle, the front wheel on that would do the exact same thing, for the exact same reason.

It's called caster angle. The reason the suspension is set up in this manner is so that the steering wheel will have a natural tendency to return to center when you let go of it, enhancing directional stability. Here is a wikipedia entry that should help you visualize it: http://en.wikipedia.org/wiki/Caster_angle

Yes I own other cars as well. It's just that the wheels don't angle out as much as the IS or they just weren't as noticeable.

Sorry if the snippet I quoted came off sounding like "duh!!"; I thought you would enjoy knowing why the wheels tilt the way they do, and I've always found that thinking about the way the front end of a bicycle or motorcycle is set up helps to understand the concept of caster. (Which is one of the measurements you'll see when you have an alignment)

Bichon, you've mistaken my response! I actually appreciate that tidbit of information. I find it interesting and never knew of this phenomenon. I was typing on the fly and might have been abrupt.

Anyway, no hard feelings at all haha
