How to Determine Percent of Tread Worn

  • Obtain the original tread depth of the new tire
  • In the groove closest to the center, measure the used tire to determine the tread remaining in 32nds of an inch.
  • The percentage worn is indicated where the tread remaining line (above chart) meets the original new tread depth column.
  • To determine the adjustment charge, multiply the percentage of tread worn by the current  dealer retail selling price.
