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.
On curved stairs, the minimum depth of the treads at their narrow end is 6 inches, and the minimum depth at the âwalklineâ is 10 inches. The walkline is measured 12 inches in from the narrowest part of the treads and follows an arc thatâs concentric to the one at the inner stair edge.
