Tire load sensitivity describes the behaviour of tires under load. Conventional pneumatic tires do not behave as classical friction theory would suggest. The load sensitivity of most real tires in their typical operating range is such that the coefficient of friction decreases as the vertical load, Fz, increases.
According to the New York Times, in the 1960s and 1970s, the typical car reached its end of life around 100,000 miles (160,000 km). Due in part to manufacturing improvements, such as tighter tolerances and better anti-corrosion coatings, in 2012 the typical car was estimated to last for 200,000 miles (320,000 km) [ 4 ] with the average car in ...
For example, soft rubbers often provide better traction but also wear faster and have higher losses when flexed—thus reducing efficiency. Choices in material selection may have a dramatic effect. For example: tires used for track racing cars may have a life of 200 km, while those used on heavy trucks may have a life approaching 100,000 km.
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...

vehicle-kilometre (vkm [1]) as a measure of traffic flow, determined by multiplying the number of vehicles on a given road or traffic network by the average length of their trips measured in kilometres. [2] vehicle-mile (vehicle miles traveled, or VMT [1]) same as before but measures the trip expressed in miles.
However, meat from sheep is generally consumed far less in the US than in many European, Central American and Asian cuisines; for example, average per-capita consumption of lamb in the United States is only 400 grams (14 oz) per year. [36] In Australia, the leg of lamb roast is considered to be the national dish. [38]
Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry [2] [3]), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and ...
