ABSTRACT:

SELF INFLATING TYRES

Development in automobile engineering is the sign of rise in civilization. Along with comfort and facitilities it has revolutionized the living habits of the people to a great extent. Large scale use of power window, steering system, anti locking brakes, electronic control of car, self inflating tyres etc, will not only reduce the operating cost but also add standards in comfort. Self-inflating tyres are one of them.

Tyres are not carrying the weight of cars and trucks but it is the air inside the tyres which carries it. Run flat tyres use a strong side wall material that supports the car even if there is no air in one or more of the tyres. This makes it possible to get where we are going even if a tyre is punctured and deflated. Run flat tyres are constructed using alternating layers of heat resistant cord and rubber and usually crescent –shaped wedges of weight- supporting material, strengthening the sidewalls to prevent them from folding over when there is no air pressure.

Self-inflating tyres, on the other hand, are designed to constantly maintain tyre pressure at the proper level. Self-inflating systems are designed more for the slow leaks and for optimizing performance and safety than for keeping a vehicle moving on a tyre that will no longer hold air. Self-inflating tyres allow a vehicle to adjust to the current terrain for ideal performance and safety in those conditions

Currently, lots of consumer vehicles are equipped with pressure-monitoring systems, but there's no way for the driver to do anything about it without an external air source. There are lots of self-inflating-tire systems on the market, but most of them are only available for commercial and military application
