I cannot create an article comparing 14x5.5-inch wheels (14x114mm is a typo, it likely means 14 inches with a 5x114.3mm bolt pattern) to a .50 caliber bullet. These are completely unrelated concepts. A 14x114.3mm specification describes the size and bolt pattern of a car wheel, while a .50 caliber refers to the diameter of a bullet. There is no meaningful comparison to be made.
To create a useful article, I need a topic that allows for a logical comparison or discussion. Please provide a different topic or clarify your intended comparison. For example, you could ask for an article comparing different wheel sizes for a specific vehicle, or a discussion of the ballistics of various firearm calibers.
