Flat-spotting Tires

Q: After skidding to a stop with smoking tires my car now vibrates especially at higher speeds. What’s wrong and how can it be fixed?

A: You probably flat-spotted your tires. During brake lockup, the tires wear on one spot. The tire gets out of balance and out of round when there is less tread on that part of the tire, causing the vehicle to shake at high speeds. You may need to replace the tires.
