what am I even looking at here? they glued a bunch of weights to the inside of the wheel? fckn wild m8
They're wheel weights for balancing. You may have some on your own wheels. It's normal to need a few. The "mechanic" who did this number likely did it as a "fuck you" to the customer. There's no way this was negligence or ineptitude.
Hanlon's razor: never attribute to malice which is adequately explained by stupidity.
If a tire is not mounted properly to the balancing machine it will tell the tech to put pounds of weights on the wheel.
