frontwheels

Front wheels are the pair of wheels located at the front of a vehicle or bicycle. In many motor vehicles they serve both steering and, in front-wheel-drive configurations, propulsion. In bicycles and some motorcycles, the front wheel is primarily responsible for steering, while drive wheels may be at the rear or both ends depending on design. The term front wheels refers to the wheels and their associated components that influence steering, suspension, and handling.

In automobiles, front wheels are connected to the steering system through components such as the steering knuckle, tie rods, and a steering rack or column. They are typically mounted to independent suspension systems, such as MacPherson struts or double wishbones, which allow vertical movement while maintaining steering alignment. Steering geometry is defined by caster, camber, and toe angles, which affect stability, steering effort, and tire wear. Front wheels often bear a substantial portion of braking forces, particularly in front-wheel-drive cars, and are commonly equipped with anti-lock braking systems and electronic stability control.

The wheel assembly comprises the rim, tire, hub, and bearings, all mounted on an axle or hub. Tire choice, inflation pressure, and wheel size influence ride quality, handling, and efficiency. Regular maintenance includes keeping tires properly inflated, balancing wheels, and performing alignment checks to prevent uneven tire wear and handling drift. Rotation intervals help distribute wear between front and rear wheels.

In bicycles, the front wheel is mounted on the fork and steered by handlebars, often featuring its own brake system and, in some models, suspension. Front wheels are fundamental to vehicle dynamics, steerability, and safety, making their condition and alignment essential for reliable operation.
