tire rubbing on inner fender when turning: Why does this happen and how can it be prevented?

When the tire of a vehicle starts to rub against the inner fender while turning, it is usually due to misalignment or improper wheel alignment. This issue can cause not only a frustrating noise but also potential damage to both the tires and the fenders. To understand why this happens, we must delve into the mechanics of a vehicle’s suspension system and the importance of proper wheel alignment.

Firstly, let’s examine the role of the suspension system. It consists of components like shocks, struts, and springs that work together to absorb road vibrations and provide a comfortable ride. The wheels, which are connected to the suspension system through ball joints and tie rods, should ideally move in unison with the steering system. However, if these components are not properly aligned or if there is wear and tear, they may start to move out of sync, leading to the rubbing sound you hear.

Secondly, improper wheel alignment can significantly contribute to this problem. Wheel alignment involves adjusting the angles of the wheels relative to the car’s frame. These angles include caster, camber, and toe settings. If any of these angles are off, it can lead to uneven tire wear and potentially cause the tires to rub against the inner fender when turning. For example, if the camber angle (the inward or outward tilt of the wheel) is too high, the tire will lean inward, causing it to scrape against the inner fender during turns.

Thirdly, the condition of the tires plays a crucial role in this situation. Tires that are worn down or have uneven tread patterns can also contribute to this issue. When tires are not properly maintained, they may become misshapen or deformed, affecting their ability to follow the intended path. Additionally, if the tires are overinflated or underinflated, it can alter their contact patch with the road, leading to abnormal wear patterns and increased chances of rubbing against the inner fender.

Fourthly, environmental factors such as potholes, speed bumps, and other irregularities in the road surface can also exacerbate the problem. These obstacles can create sudden changes in the car’s trajectory, forcing the wheels to make sudden adjustments, which may lead to the tires rubbing against the inner fender. Over time, repeated exposure to these conditions can cause further wear and tear on the suspension system, making the problem worse.

To prevent this issue, regular maintenance of your vehicle is essential. This includes checking the alignment of all four wheels, ensuring proper tire pressure, and inspecting the overall condition of the suspension system. Professional alignment services can help ensure that your vehicle is running smoothly and efficiently. Additionally, maintaining a safe driving routine, avoiding abrupt maneuvers, and driving at consistent speeds can help minimize the likelihood of this problem occurring.

In conclusion, the issue of tire rubbing against the inner fender during turns is often caused by misalignment or improper wheel alignment. Proper maintenance and regular checks can help prevent this from happening, ensuring a smoother and more comfortable driving experience for you.
