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.
East Lansing
East Lansing is a city in the U.S. state of Michigan directly east of Lansing, the state capital. Most of the city is within Ingham County, with the rest in Clinton County. The population was 48,579 at the 2010 census, an increase from 46,420 in 2000. It is best known as the home of Michigan State University.
East Lansing was an important junction of two major Native American groups: the Potawatomi and Fox.[6] By 1850, the Lansing and Howell Plank Road Company was established to connect a toll road to the Detroit and Howell Plank Road, improving travel between Detroit and Lansing, which cut right through what is now East Lansing. The toll road was finished in 1853, and included seven tollhouses between Lansing and Howell.[7]
Michigan State University was founded in 1855 and established in what is now East Lansing in 1857. For the first four decades, the students and faculty lived almost entirely on the college campus. A few commuted from Lansing, and that number increased when a streetcar line was built in the 1890s, but there were few places to live in the then-rural area immediately around the campus.
That started to change in 1887, when professors William J. Beal and Rolla C. Carpenter created Collegeville, along what is now Harrison Road and Center and Beal Streets, north of Michigan Avenue. Few faculty were attracted to the location, and the first residents were “teamsters and laborers”.[8] In 1898, the College Delta subdivision (including what is now Delta Street) had the support of the college itself, which provided utilities, and several professors built homes there (one of which survives today at 243 W. Grand River Ave.).[9] Other subdivisions followed.
At that time, the post office address was “Agricultural College, Michigan.” A school district encompassing the nascent community was created in 1900. In 1907, incorporation as a city was proposed under the name “College Park”; the legislature approved the charter but changed the name to “East Lansing.” The first seven mayors, starting with Clinton D. Smith in 1907 and Warren Babcock in 1908, were professors or employees of the college.
