Mitral valve stenosis can be treated using percutaneous (keyhole), minimally invasive or standard surgery. Keyhole techniques, where a balloon is inflated inside the valve via a wire in the groin (balloon valvotomy), are the first line of treatment if the mitral valve is not heavily calcified. This can be repeated as needed over several years.
You can only mount a tire of equivalent load or higher load than indicated for your vehicle. The higher the tire's load index number, the greater its load carrying capacity. Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 130. See full table
The first two digits (87S) represent the tire's load index and are followed by a single letter (87S) identifying the tire's speed rating. Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire's service description. A service description identifies the tire's load index and speed rating. Service descriptions are required on all speed rated (except for Z-speed rated) tires manufactured since 1991. The first two digits (87S) represent the tire's load index and are followed by a single letter (87S) identifying the tire's speed rating.
