Hypercapnia is an unusually high concentration of carbon dioxide in the blood which may be accompanied by hypoxemia, in which the oxygen level in the blood is low. This condition occurs as a result of poor gas exchange at the lungs which makes it difficult for people to eliminate carbon dioxide from their bodies.
Quick Answer. A tire treadwear rating refers to the amount of time the treads on a tire should last in specific conditions. Tire manufacturers indicate treadwear rating on their tires using a set of numbers between 100 and 700. These numbers indicate how long tire treads will remain safe and perform at their highest capacity.
If a vehicleâs tires are âtoe-outâ (also known as negative toe), the front of each tire is angled outward. It is actually normal for a vehicleâs tires to have a tiny amount of toe. The amount of toe can increase due to wheels being out of alignment, and that is when it can cause your tires to wear prematurely. A tire with toe wear will typically be worn on the inside shoulder of the tire. That is, it will have a smooth strip of wear around it on the side that is facing the wheel well.
