The number 50 in tire measurements does not specifically denote a low profile tire on its own. It actually refers to the aspect ratio, which is the height of the tire's sidewall expressed as a percentage of its width. A tire marked with a '50' means the sidewall height is 50% of its width. Generally, tires with an aspect ratio of 55 or lower are considered low profile. The overall profile of a tire depends on other factors including the width and diameter as well.
