Trucks are put into a class apart from passenger cars due to the fact that they are designed for heavy duty work. The can be separated into two categories: light and heavy.
Light trucks like sports utility vehicles (SUVs) and pickups usually carry passengers like regular cars. The difference is that they are not limited to the road since their tires are specialized to go over rough terrain. They can also carry light loads.
Heavy trucks like fire engines, buses, tractor-trailers, tankers, U-Hauls, flatbeds, and cement mixers are designed to deal with heavier workloads. Their tires are also specialized to deal with rough terrain. These trucks are usually used for construction and shipping, and can travel long distances.
The pressure in a truck tire is important to know, and is a safety requirement by most trucking companies. The average tire pressure in a truck tire varies from model to model. It is determined by the speed at which a specific truck will travel, the type of load that it carries, and the conditions in which it will travel. According to the Society of Automotive Engineers the average pressure in a truck tire can range from 30 to 100 psi (pound-force per square inch) or 150 to 700 kPa (kilopascal). Pressure is defined by the formula P = F/A (force divide by area).
