If the Tire is squealing when turning, this particular problem most often indicates that something is wrong with the wheel alignment. However, it can also be caused by one or more improperly inflated cars.

The first thing to do is to check each tire's Pressure.

Using a tire pressure gauge, check the air pressure of each tire and compare it to what it's supposed to be (refer to the vehicle's owner's manual if you are unsure of the correct pressure).

If any of the tire pressure readings significantly low or high, therefore, Squealing is probably caused by improper tire pressure. Actually, for a tire to have good traction, it must be properly inflated. More specifically, a tire that is either underinflated or overinflated will have a tendency to slip (very slightly) when the vehicle is turning a corner (even at normal speed). As you probably guessed, the Squealing is a result of the tires slipping (again, very slightly).

Add/release air from whichever tires aren't properly inflated. Hopefully, this will eliminate the squealing. If not, please re-run the consultation and try again. However, if any of the tire pressure readings significantly low or high, rule out improper tire pressure.

The possible cause is a steering angle problem or misalignment.

In very basic terms, when a vehicle is turning a corner, the wheels must be at the correct "steering angle" (this is part of a vehicle's "alignment"), or else the tires will slightly drag across the pavement - this results in the screeching sound you're hearing.

Get an alignment job done on this vehicle. Please note that this problem is causing the tires which are squealing to wear faster than normal. Therefore, get an alignment soon to avoid further wear.

Some mechanics may tell you they can't do an alignment properly without first replacing one or more front end parts. If this is what a mechanic tells you, get a second opinion before proceeding with any such repairs.

Try to find a garage that is approved by the AAA. Such garages tend to be reputable and, best of all, if you do have a dispute after the work is done, the AAA has the policy to investigate the situation and resolve it.
