What Causes a Regular Zizzing Sound from Tires?

[AthenaLee]

Tires making a regular zizzing sound may be due to foreign objects on the tires or brake pad noise. It is advisable to promptly inspect, clean, or replace the brake pads. Below is the method for replacing brake pads: 1. Release the handbrake and loosen the hub nuts of the wheel where the brake needs to be replaced. Note: only loosen them, do not remove them completely. 2. Remove the screws of the brake caliper. 3. Secure the brake caliper with a rope to avoid damaging the brake line. Then remove the old brake pads. 4. Use a C-clamp to push the brake piston back to the innermost position and install the new brake pads. Note: Before doing this, open the hood and unscrew the cap of the brake fluid reservoir. This is because the brake fluid level will rise when pushing the brake piston. 5. Reinstall the brake caliper and tighten the caliper screws to the required torque. 6. Reinstall the tire and tighten the hub nuts.

A rhythmic hissing sound from the tires is likely caused by small stones, nails, or metal fragments stuck in the tread. I've encountered this situation myself, where the noise resembles a constant rubbing sound while driving. This occurs because foreign objects penetrate the tire and rub against the road surface. If not addressed promptly, it may scratch the tread or cause slow air leakage, posing significant safety risks. It's advisable to immediately find a safe place to pull over and inspect the tire surface for any obvious lodged objects. If found, try removing them with tools. However, if the sound persists or the cause remains unclear, it's best to drive to a nearby repair shop for professional inspection. Regularly cleaning the tire grooves can prevent such issues, ensuring safer and more worry-free driving.

I also used to hear a constant ticking sound from the tires when I first started driving, as regular as a clock. This is usually caused by unbalanced tires or uneven wear. Check if the tread depth is normal or if the wheels are out of round or deformed. Sometimes poor driving habits, like slamming on the brakes or taking turns too fast, can accelerate tire problems. The sound might become more noticeable at certain speeds, like around 40 km/h. You can't adjust it yourself—you'll need to go to a tire shop for a dynamic balance check. Don't ignore this sound, or it could lead to a blowout on long trips. Regularly check your tire condition and ensure proper tire pressure to greatly reduce the chance of strange noises. Drive carefully—safety first.

A rhythmic hissing noise from the tires is mostly caused by worn bearings or loose suspension components. When the car moves, the weight presses on the wheels, and if the bearings are damaged, metal friction can produce this sound. Worn ball joints or suspension links may also be the culprit. Start by locating the sound: it may be faint at low speeds but louder at high speeds. This issue should be addressed early, as it can affect handling and increase fuel consumption. Use a jack to lift the car and shake the wheel to check for looseness. If the bearings are damaged, they need replacement. The repair isn't complicated, but DIY disassembly isn't recommended. Visit a trusted repair shop to inspect the entire chassis and check the brake pads, as sometimes the noise originates there. Proper maintenance can be life-saving.
