Self-inflatable Tires
Well it's about time someone invented this! This has got to be one of the best inventions of 2012! Air pumps will be the thing of the past! At least for the commercial vehicles... for now.
Tire-related costs are the single largest maintenance item for commercial vehicle fleet operators with more than 50 percent of all truck and trailer breakdowns involving a tire in some way. Goodyear's Air Maintenance Technology mechanism allows tires to maintain constant, optimum pressure without the use of external pumps, electronics and driver intervention.
Proper tire inflation can result in improved fuel economy, prolonged tread life and optimized tire performance.
