Cost-Effectiveness: Inflatable tires are less expensive to manufacture than solid or alternative tire types. Their widespread use contributes to economies of scale, resulting in lower prices for consumers.
In technical terms, an inflatable tire consists of an outer casing (tread), inner lining (inner tube), and a layer that maintains air pressure. The tire operates on the principle of “pneumatics,” which refers to the use of pressurized air. This pressure supports the weight of the vehicle and maintains the tire’s shape, allowing it to deform slightly when it contacts the road, which maximizes grip.
Specific conditions that contribute to the preference for inflatable tires include:
-
Diverse Driving Conditions: Inflatable tires perform well on various surfaces, such as wet, dry, and uneven terrain. Their design adapts to the contours of the road.
