The circle of forces, traction circle, friction circle, [1] or friction ellipse [2] [3] [4] is a useful way to think about the dynamic interaction between a vehicle's tire and the road surface. The diagram below shows the tire from above, so that the road surface lies in the xy - plane .
Its hubless wheels are made from former truck tires, and a chain-driven friction drum provides power and brake force. [6] Designed "for casual cruising and slow ride-bys at shows", it consists of a 996 cc (60.8 cu in) fuel-injected Suzuki 4-stroke engine [7] in a steel frame covered by a fiberglass body with electroluminescent wire lighting.

The front-engine, rear-wheel drive layout (abbreviated as FR layout) is one where the engine is located at the front of the vehicle and driven wheels are located at the rear. [3] This was the traditional automobile layout for most of the 20th century, and remains the most common layout for rear-wheel drive vehicles. [4]
Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
Tire forces are divided into three axes: radial, lateral, and tangential (or fore-aft). The radial axis runs from the tire center toward the tread, and is the vertical axis running from the roadway through the tire center toward the vehicle. This axis supports the vehicle's weight. The lateral axis runs sideways across the tread.
Staggered wheel fitment usually appears on rear-wheel drive vehicles (and in smaller numbers some all wheel drive cars), when the rear wheels are wider than the front wheels. [11] Such a wheel setup may be found on the Ford Mustang, Infiniti G35, certain models of Mercedes and BMW, etc. A good example of such wheel combination is having 19 in ...
Performance vehicles may run zero front toe or even some toe-out for a better response to steering inputs. Increased front toe-in marginally increases the wear on the tires as the tires are under slight side slip conditions when the steering is set straight ahead. On front-wheel drive vehicles, the situation is more complex. Rear toe-in ...
Figure 1 Hard wheel rolling on and deforming a soft surface, resulting in the reaction force R from the surface having a component that opposes the motion. (W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown.
