I get this squealing noise when doing a full turn, even on low-speed turns. I can't really tell if its just the tires.

Where or what else should I look at?

Welcome to the forum.

If it's on a relatively slick surface, then it's probably the tires.

Front tires will scrub on hard turns, surface/tire/weather conditions will dictate if the squeal or not.
Turn the steering wheel full left and/or right.
Then go out and stand away from the frontend. You will notice that the front tires are not pointing in the exact same direction.
So they fight each other for traction resulting in one losing out to the other and scrubbing sideways.
Physics says the inside turn tire will lose traction first.

My 07 Tahoe with the factory Bridgestones, squeal during turns in parking lots and the kids accuses me of squealing the tires...
its tire friction...

If what your hearing is a moan when you fully turn either way it is the blowoff/bypass valve in the steering box that lets off all the pressure in the system that builds up in order not to break anything. If thats not what your talking about, respond to me more details see if i can help you out.
