The original type of spoked wheel with wooden spokes was used for horse-drawn carriages and wagons. In early motor cars, wooden spoked wheels of the artillery type were normally used. In a simple wooden wheel, a load on the hub causes the wheel rim to flatten slightly against the ground as the lowermost wooden spoke shortens and compresses.
The first patent for wire wheels was issued to Theodore Jones of London, England on October 11, 1826. [5] Eugène Meyer of Paris, France was the first person to receive, in 1869, a patent for wire wheels on bicycles. [6] Bicycle wheels were not strong enough for cars until the development of tangentially spoked wheels.
The wagon-wheel effect is most often seen in film or television depictions of stagecoaches or wagons in Western movies, although recordings of any regularly spoked rotating object will show it, such as helicopter rotors, aircraft propellers and car rims. In these recorded media, the effect is a result of temporal aliasing. [1]
Wire spokes are under tension, not compression, making it possible for the wheel to be both stiff and light. Early radially-spoked wire wheels gave rise to tangentially-spoked wire wheels, which were widely used on cars into the late 20th century. Cast alloy wheels are now more commonly used; forged alloy wheels are used when weight is critical.
Construction of wire-spoked wheels is generally termed as wheelbuilding, so wheel construction refers to construction of non-wire wheels, e.g. wheels of cars and other heavier vehicles. Wheels are constructed in a wide variety of designs using different materials, but in the early 21st century, aluminum and steel are most often used, with steel ...
Most conventional bicycle wheels now use 32 or 36 spokes front and rear, although the asymmetry of the rear wheel (to allow for the cluster of sprockets), and the additional weight it carries, means it benefits from having more spokes than the front. Commonly used models vary from 18 spokes for racing bikes to 36 for cross-country touring bikes ...

The rear wheels of single-seat racing cars are driven by driveshafts from the transaxle and the brakes are usually mounted inboard in any case, away from the wheels. [16] Later Lotus designs, from the 26 onwards, used spoked wheels, although this was more about the shrinking diameter of racing tyres, especially fronts, rather than brake cooling.
