Hmmm, perhaps. Of course your best bet would be to have a mechanic have a look see. It could be many things, a simple need for lubrication, something out of alignment, brake pads worn down... recently a wheel bearing went on my car, and it exhibited similar symptoms, ie the tires screeching when they moved, not actual of problem with the tires, but more what they are attached to, so I would say you most probably don't need new tires, and it is unlikely you would have to replace the steering....

It's neither, It's your fanbelt slipping and making a squealing noise. Go out and either pour liquid soap on your fanbelt or gently rub it with abrasive paper (to help it grip on the turning wheels) or simply get a new fanbelt. I bet it happens more when it's wet. Am I right?
This is the problem, had the same problem with my 98 Nissian 4x4, put liquid soap on the belt and had it tightened a notch. Works great now.
