Holy shit my brother I had seen these things for years, thrown in the ground and always figured they had something to do with cars, only didn't know WHAT. you sir have scratched that mental itch and my brain lobes are forever thankful
Oh shit. I had an old beater that would shake apart at certain rpms. It was a hand me down that I drove into the ground and didn't spend money on, so I never got it inspected. Didn't know the solution was so easy.
I got a flat tire and needed to replace the tires. Since I was going to get new tires soon anyway my quick replacement was a used tire different from my others.
My car was unbalanced and it felt so weird, had to keep checking if I got another flat because the vibration feeling was so off.
