What is the reason for the hissing sound from the left front wheel?

The reason for the hissing sound from the left front wheel is: there are some stones or other foreign objects on the tire. When this happens, it is recommended to clean the foreign objects on the tire surface. Tires are rubber products, and rubber products will age after long-term use, so tires need to be replaced regularly. Tires are a relatively important component of a car, being the only part that comes into contact with the ground. They are usually mounted on metal rims, supporting the vehicle body and cushioning external impacts. Tires are crucial for the driving safety and stability of the car. Under normal circumstances, tires can be used for four years after being installed on a car, and it is recommended that car owners replace their tires every four years.

As a seasoned long-distance driver, I've encountered the issue of wheel squealing several times, especially with the left front wheel. This sound is mostly caused by worn-out brake pads, where the metal grinds against the brake disc, creating a nerve-wracking noise. It could also be due to worn wheel bearings, which produce even more annoying noises when damaged; or small stones stuck in the tire treads, though these are usually removed during car washes. Ignoring these issues can turn minor problems into major ones. I once neglected them and almost had a brake failure, costing me a lot more in repairs. I suggest you stop immediately for a quick check to see if the tire surface is clean; if everything seems fine, don't delay—head straight to a professional auto repair shop for a thorough diagnosis. Safe driving should never be taken lightly. Regular maintenance and component checks, like inspecting brake pad thickness monthly, can prevent problems before they arise.

I've only had my car for a little over a year, and recently the left front wheel started making a squealing noise, which made me nervous while driving. My mechanic friend said common causes are usually either the brake pads being too thin and needing replacement, or some issue with the wheel bearings; if there's a small stone stuck in the tire, it can also cause a squealing sound, especially more noticeable during rainy days. I immediately took it to the shop and found out it was excessive brake pad wear. If not repaired in time, I would have regretted it if an accident happened. My advice is not to panic and start with the simple things: after parking, visually check the tires for any foreign objects; if none, drive straight to a repair shop for a professional inspection with proper tools. Driving with persistent noise is too dangerous, so don't try to save a few bucks. Develop a habit of walking around the car to check components every time you refuel, as a preventive measure against similar issues.

I'm quite interested in cars. The buzzing sound mostly comes from the brake system in the left front wheel area, such as worn-out brake pads or metal debris stuck in them; damaged wheel bearings can also produce a harsh friction noise; or loose suspension components causing vibrations. I recommend first observing the noise characteristics: check if there are any stones stuck in the tires when parked; if the sound gets louder when turning while driving, it's likely a bearing issue. Simple problems can be handled by yourself, but professional diagnosis is more reliable—don't rush to disassemble anything. For safety's sake, visit a repair shop early to identify the issue and avoid costly major repairs.
