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.
In the UK, 1.6mm across 75% of the width of the tread. There is no national law in the U.S. on tread depth. However 42 states consider 2/32 the minimum. California & Idaho coâ¦nsider 1/32 the minimum. Arkansas, Montana, New Mexico, North Dakota, South Carolina, and West Virginia have no minimum. A tire below 3/32 cannot pass the Texas safety inspection. In Canada the minimum is 2/32. Some experts including Consumer Reports consider 4/32 the minimum. My opinion is that when the tire has less than 3/32 it should be replaced.
