We all have faced the situation of flat tire. Well, if it happens close to some garage then, it’s easy escape from arduous effort of getting it towed or pushing your car all the way to garage. But, if it happens in the middle of the road then feeling of being stranded is haunting. Technology have given a respite for such perilous situations as several tire manufacturers have developed tires that allow a vehicle to travel even with loss of pressure. There are two different approaches for this achievement
Reinforced Tire Sidewall:
Manufacturers that produce these include Bridgestone, Continental, Dunlop, Goodyear, and Pirelli. These tires can be placed on any rim. The sidewall is very well reinforced allowing the tire to support the vehicle’s entire weight. The tire is made with new rubber compounds that prevent tire damage with excessive flexing. Such tires allow a vehicle to still run effectively even with total loss of tire pressure. Braking, acceleration, and steering behavior remain unchanged in such condition and gives sufficient mobility after puncture to reach to any nearby garage.
Rubber clip on tire rim
The rubber clip prevents the tire rim cutting into your tire when you experience a sudden loss of pressure. This system has been developed by Michelin and is known as the PAX System. Like the reinforced sidewall it operates in tandem with automated tire pressure monitors.
All flat tires need not be a puncture, as it turns out many times there is loss of pressure even in good tires too. The reason for this loss of pressure is difference in ambient temperature which causes compression and expansion of air inside the tire. Atmospheric air contains moisture which expands and contract much more than inert gases like nitrogen. So loss of pressure in all compressed air filled tires is inevitable. Best way to avoid loss of pressure is to fill tires with 100 % nitrogen.
Why fill my tires with Nitrogen?
Why would you want to do this? The benefits of Nitrogen filling are as follows are plenty starting with improved comfort of ride, improved safety, increased fuel savings, improved life of tire
Nitrogen has long been the accepted gas medium for filling aircraft tires, racing tires and heavy mining and construction vehicle tires.
Nitrogen is used for safety reasons and to ensure that tires are always at a constant pressure. Compressed air, the traditional medium for inflating car tires, contains both oxygen (21%) and nitrogen (78%).
The rubber tire is like a membrane, through which oxygen permeates three times faster than the nitrogen. The result is that the oxygen slowly leaks out through the rubber walls, and the under-inflation leads to higher tire wear with a consequent decrease in safety and comfort, and higher fuel costs.
