The sound of metal grinding
The brake pads are too thin
The front-wheel brake pads of a car are generally electronic, the rear wheel is not, but most have a mechanical alarm. When the brake disc is worn too thin, a metal friction sound is emitted. When you don't hit the brakes, it's very slight. When you hit the brakes, it's louder and more jarring. Now you must take your time to change the brake.

Excessive tire pressure and abnormal noise
In general, the tire pressure of a car should be about 2.4bar before and after no-load, about 2.6bar before and 2.7bar after full load. Each car also has a difference, the specific accurate value sees their own car's instruction book. The tire pressure was so high that not only did you hear the tire noise when you ran, but you also felt as if the suspension was stiffening, bouncing, and drifting slightly. In this case, just let the air out and bring the pressure back to standard. For cars with a tire pressure monitor, this happens very rarely, because it can be seen at the top of the charge.
The bolts were not tightened properly
The sound is the moment the vehicle goes and stops, there is a "clang" "clang" sound, acceleration, and deceleration steering also has a clear sound. It's very loose, and you can feel the body twisting when you're driving, and it's hard to handle. The solution is to retighten the bolts, but it is recommended that you go to the repair shop as soon as possible to check whether the bolts or the bolt holes on the rim are damaged and if so, replace them.
