HOW TO KNOW WHEN CAR TIRES NEED REPLACING

  • Look for the wear indicators in the major grooves. Replace the tire immediately when the tread wear indicator shows.
  • Check for minimum tread depth using the tread depth measure.
  • Perform a visual inspection of the tread and sidewall. If there is any exposed steel or fabric and if any material is visible, have the tire(s) replaced immediately.
