Tires
A tire (American English) or tyre (British English)[1] is a ring-shaped vehicle component that covers the wheel’s rim to protect it and enable better vehicle performance. Most tires, such as those for automobiles and bicycles, providetraction between the vehicle and the road while providing a flexible cushion that absorbs shock.
The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon blackand other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal that fitted around wooden wheels to prevent wear and tear. Early rubber tires were solid (not pneumatic). Today, the majority of tires are pneumatic inflatable structures, comprising a doughnut-shaped body of cords and wires encased in rubber and generally filled with compressed air to form an inflatable cushion. Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are still used on locomotives and railcars, and solid rubber (or other polymer) tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.
Valley Park
Valley Park is a city in St. Louis County, Missouri, United States. The population was 6,942 at the 2010 census.[6]
Descendants of the Mississippian culture still had a settlement along the Meramec River in the mid-18th century, until the Native Americans were pushed out by colonial French and German immigrant farmers in the 1760s.{{citation needed|date=May 2017}] The developing village over time was known as Nasby, Sulphur Springs, Quinette, Meramec, and finally Valley Park by around 1890. It had one of the first post offices established in St. Louis County. It developed as a railroad hub for the Missouri Pacific and St. Louis-San Francisco rail lines.
In 1894, the town became the site of the first lynching in St. Louis County. A black man named John Buckner was lynched when accused of raping a local black woman and a white teenager. He was taken from the authorities by several local residents and farmers and hanged from the main bridge in town overlooking the Meramec River. The lynchers were never prosecuted.
