When I got my Wesbank statement yesterday, it was pretty obvious that the format had changed. However, it was only once I compared the statement to my accounting record that the extent of the change became apparent.
â¦Tread Depth Lea esta pgina en espaol Tread Depth Tread depth is a vertical measurement between the top of the tread rubber to the bottom of the tire's deepest grooves. In the United States, tread depth is measured in 32nds of an inch.
The final 2/32 of a tire's tread depth isn't part of the equation when it comes to calculating tread depth percentages because the tire is already legally worn out with just 2/32 of remaining tread depth.. Useable tread depth is calculated by subtracting 2/32 from the tires' new tread depth.
