The size of a wheel is typically described using a specific format. For example, when purchasing a wheel, you might see something like 18x8.5, 5x114.3, +42. Here's what each part means: 18 refers to the diameter of the wheel in inches, 8.5 is the width of the wheel (also in inches), 5 represents the number of bolt holes, 114.3 is the distance between those bolt holes in millimeters, and +42 indicates the offset, which is how far the wheel sits in relation to the hub (in this case, 42 mm forward). So, there's no actual concept of "thickness" or "thinness" when it comes to the wheel itself.
Now, let’s take a look at tires. A tire marking like 245/40-18 gives you several key details. The first number, 245, is the width of the tire in millimeters. The second number, 40, is the aspect ratio — which can be thought of as the "height" or "thickness" of the tire’s sidewall relative to its width. The last number, 18, refers to the rim diameter in inches. So, when someone talks about a "thicker" or "thinner" tire, they're most likely referring to the aspect ratio.
The combination of a wheel and tire is crucial for proper fitment and performance. For example, if your car originally comes with a 16x7 wheel paired with 225/55-16 tires, upgrading might involve moving to an 18x8.5 wheel with 245/40-18 tires. As the wheel diameter increases, the tire's width also increases, while the aspect ratio decreases, making the tire appear "thinner." This adjustment helps maintain the overall diameter of the tire, preventing issues like speedometer inaccuracies or interference with the vehicle's body. If the tire thickness remained the same, the larger wheel could cause the tire to rub against the car’s fenders or suspension components. So, it's all about balance and compatibility.
