How do you know if a lug nut is too tight?

If the lug nuts on the wheels are not tightened properly, the lug nuts are likely loose. To test the tightness of the lug nuts, check the torque settings with a torque wrench.

The brake rotors withstand a lot of heat during the process of braking, and need to dissipate this heat quickly so that the brake pads will be able to be pressed down again. Because of this mass amount of heat, the surface of the brake rotors can become uneven over time, which is often referred to as warping.

Can over torquing wheels cause vibration?

Overtorquing the lugs will cause a vibration via rotor warping, but only during brake application, it will not cause a static vibration, unless the warp is so huge that braking would be dramatically effected.

Will warped rotors fix themselves?

Will warped rotors fix themselves? No, it’s not possible for brake rotors to unwarp themselves. Rotors rarely “warp.” If they actually did so, they you would notice vibration even when the brakes are not applied (think about it, the pads on either side scarely clearly the rotors but by a few thousandths).
