Why do car tires squeal when you turn corners in parking garages even at very low speeds?

The floors are sealed with a material that is very grippy, much more so than concrete or asphalt. Your tires don’t roll perfect when turning, the edges slip, on most roads there’s a bit of give, pebbles or sand/dust, and these materials allow the edges of the tire to slide. On the floor seal the rubber slips and vibrates at a frequency that causes the sound you hear.
Rub a balloon and it’s squeaky, rub a balloon with a handful of sand and it’s not squeaky. Same thing.
When you’re turning, the outside edge of the tire moves ever so slightly faster than the inside edge. This causes one part of your tire to grip and stay stationary with respect to the floor and the other part to slip and make the squeaking noise.
Chances are that you either have a bad differential or have accidentally turned 4WD on. It should not squeal if everything is as it should be.
probably because it isn’t possible (geometrically speaking) for all four tires to move along their “rolling axis” (there’s no such name i just made it up). By that i mean, the “x” axis on the sketch below. Necessarily, there will be one or more tires that will be slipping (which means, moving along the “y” axis on the sketch below)
sketch in question, found on google: [https://www.researchgate.net/profile/Dhananjay-Thombare/publication/264991925/figure/fig1/AS:392049141534721@1470483207277/Tire-Axis-Terminology.png](https://www.researchgate.net/profile/Dhananjay-Thombare/publication/264991925/figure/fig1/AS:392049141534721@1470483207277/Tire-Axis-Terminology.png)
For a car with four wheels, and where the two front wheels always face the same direction, as well as the two rear wheels, the only case where all four tires may roll without slipping (a.k.a, no movement along the “y” axis for any of them), is when the car is rolling in a straight line with all four tires directed in the same direction. Otherwise, they will be slipping, and i guess it slips all the more as you’re making a close turn (like when you’re parking)
I can’t say for sure, but i would say it is the slipping that is making the sound you’re talking about.
