What Causes the Squeaking Sound from the Rear Tires of a Car?
2 Answers
It may be due to worn brake pads, thinning brake linings, or direct contact between the brake drum and the vehicle, causing metal-to-metal friction and resulting in abnormal noise. Below is relevant information: 1. Types of Tires: Pneumatic tires are further divided into tubed tires and tubeless tires based on their structural composition. Passenger cars commonly use tubeless tires. Depending on the arrangement of the internal cord layers and cushion layers, tires can also be categorized into radial tires and bias-ply tires. Radial tires are widely used in automobiles, and their specifications are marked on the tire sidewalls. 2. Functions of Tires: Tires are in direct contact with the road surface and, together with the vehicle's suspension system, help absorb shocks during driving, ensuring good ride comfort and smooth operation. They also ensure excellent adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and maneuverability. Additionally, tires bear the weight of the car.
I've been driving for twenty years, and squeaky rear wheels are all too common. It's mostly because the brake pads are nearly worn out or something got stuck in the brake drum. Once during a long road trip, the noise kept getting louder, and I almost couldn't stop halfway—luckily, I checked in time to avoid disaster. It could also be low tire pressure increasing friction and causing noise, or small stones stuck in the tread making a squeak with every rotation. Loose or damaged suspension parts can also cause such sounds. I always remind folks not to ignore it—pull over and do a quick check if you hear anything, and head straight to the repair shop if needed. Safety is more important than anything. Making a habit of regularly checking tires and brakes can save a lot of hassle.
