Car wheels on a gravel road create a distinct sound and feel compared to driving on paved surfaces. The uneven texture of the gravel can lead to a bumpy ride, as the wheels navigate loose stones and varying depths. This can affect traction and handling, requiring drivers to adjust their speed and steering. The composition of gravel typically includes small stones and sand, which can shift under the weight of a vehicle. This shifting can cause the wheels to slip or slide, especially in wet conditions. Proper tire maintenance is essential for optimal performance on such surfaces, ensuring safety and control while driving.
