Patients with severe mitral regurgitation, a condition in which the heart's mitral valve does not close and seal properly, have a new, minimally invasive treatment option. The MitraClip system is a procedure that uses a small clip to repair the heart's mitral valve to treat mitral regurgitation.
Here in the U.S., tire tread is measured in 32nds of an inch. A brand-new tire has a tread depth around 10/32nds of an inch (approximately 1/3 of an inch). Some tires, like winter tires or off-road tires, may have a deeper tread. As you drive on the tires, the tread gradually wears down. If you reach the point where thereâs 2/32nds of an inch of tread or less left, the tires are bald and are considered legally worn out in most states.
Tread depth will determine the overall length of the stairs from the riser of the bottom step to topmost riser. Code says that minimum depth of tread, where you step, is no less than 10. For service steps that may work, I try for a depth between 10 1/2 and 11 is more comfortable for many people.
