Tire Safety

Worn tires cannot grip the road and can be extremely hazardous – think of tires as your lifeline in a car; the few square inches of rubber contacting the pavement is all that is between you and potential trouble.

Did you know…?

  • At 50 MPH on a wet road, worn tires need 130 feet to stop – new tires only need 85 feet. That’s a difference of 3.5 car lengths!
  • In one day last winter, CDOT assisted 22 vehicles that spun out and blocked traffic or caused an accident- 19 out of those 22 had bald tires.

Know if you need new tires? Take the Quarter Test!

  • Insert a quarter into the tire tread upside down, with Washington’s head going in first
  • If the top of George’s head is covered by the tread, your tires are OK – do this test at multiple points around each tire
  • If the top of his head is visible at any point around the tire, you need new tires
