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.
Therefore the vehicle's stopping distance increases. Although the legal minimum tread depth is only 1.6mm, independent research at MIRA shows that tyres with 3mm of tread have an average 25% better performance than those at 1.6mm-which represents an extra 8 metres stopping distance in wet conditions.
