The common symptoms of out-of-balance tires are uneven and faster tread wear, poor fuel economy, and vibration in the steering wheel, the floorboard or the seat that gets worse at faster speeds. When all areas of the wheel-tire unit are as equal in weight as possible, the tire will roll smoothly.

Can bad rotors cause vibration at high speeds?

Worn Out Brake Pads And Rotors

Typically, if your vibration increases with speed, and you smell a burning noise when running the car, warped brake rotors are likely the cause of your vibrations.

Does alignment fix vibration?

In most cases, a wheel alignment will stop the shaking by ensuring all wheels are positioned in the same direction. One of the quickest ways to diagnose misalignment is to check the tire's tread. A vehicle out of alignment will often make tires wear unevenly, with the inside tread worn much more than the outside.
