    P – these tires are for a passenger vehicle. However 'P' denotes P metric size load and speed rating changes for P tire & non-P tires; 195 – the nominal width of the tire is approximately 195 mm at the widest point; 55 – indicates that the height of the sidewall of the tire is 55% of the width (107 mm) R – this is a radial tire

    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.

  5. Tire balance - Wikipedia

    en.wikipedia.org/wiki/Tire_balance

    In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 RPM (10 to 15 mph with recent high sensitivity sensors) or higher, 300 RPM (55 to 60 mph with typical low sensitivity sensors), and forces of unbalance are measured by sensors.

  6. Wheel sizing - Wikipedia

    en.wikipedia.org/wiki/Wheel_sizing

    The wheel size is the size designation of a wheel given by its diameter, width, and offset. The diameter of the wheel is the diameter of the cylindrical surface on which the tire bead rides. The width is the inside distance between the bead seat faces. The offset is the distance from the wheel's true centerline (half the width) to the wheel's ...

  7. Overdrive (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Overdrive_(mechanics)

    A plate warns to only engage the unit in third and fourth gears. Overdrive is the operation of an automobile cruising at sustained speed with reduced engine speed (rpm), leading to better fuel consumption, lower noise, and lower wear. [1] The term is ambiguous. [1] The most fundamental meaning is that of an overall gear ratio between engine and ...
