Squeaking or squealing on your car is usually indicative that something isn't working properly. These noises are potential signs of serious problems that could damage your car and put your safety at risk.

If you notice your car making any abnormal squeaking or squealing noises, stop by a Pep Boys today to have any potential problems diagnosed and rectified.

Here are some of the most common explanations for unwanted vehicle noises and what you can do to stop them.

Underinflated Tires

Underinflated tires are probably the most common cause of squeals, usually on sharp turns or when your car is taking corners. Though there are other warning signs when your tires need more air, this is one is more obvious and typically motivates you to get to fill your tires. Underinflated tires perform poorly in inclement weather and lead to downgrades in traction, so these are squeals that you do not want to ignore. Air fills are usually as cheap as a quarter, though we recommend you invest in a tire pressure gauge if you do not already have one, just to make sure you are not overinflating your tires when you fill them up.

Uneven Tread Wear

Squealing and squeaking can also be a sign of worn down or uneven tire tread wear. Over time and with high usage, tire tread starts to break down. Tread blocks will become dull or peel off the surface of your tire, resulting in uneven tread patterns and depths. Tire tread is what gives your vehicle the gripping strength as it meets the road, so when it starts to wear out, braking and turning becomes more difficult and abrupt. This is when you will start to hear your tires squeal. Have your tires rotated and balanced regularly at your local Pep Boys to get the maximum tread life out of your tires.

Loose Wheels

One of the less noticeable causes of squeaking and squealing in your tires could be loose wheel covers or lugs. You probably won't encounter these as often as an underinflated tire or uneven tread wear, but hitting a nasty bump or edge in the road could jar the lugs (or bolts of the wheel) loose, creating awkward friction between the outer surface of the wheel and the tire. Fixing this is usually simple, but your safest bet is to take it to your mechanic to have the lugs tightened and the wheels checked for any structural damage that could cause issues somewhere down the road.


There is always a possibility that the noises you hear are coming from parts of your car that are not the tires. Squeaking noises can often be an indication that something might be wrong with your brakes - most commonly because of issues with the brake pads and rotor vibrations. If you're not sure what sound you're hearing, go to our bad brake noise page to determine the issue you may be having with your brakes.

Other Causes

Structural problems to the interior or exterior of your car can cause similar noises. You should always err on the side of caution and get these noises checked by a trusted car expert before they turn into more serious problems and impact your safety.
