A new innovative self-inflating tire called PumpTire is now looking for pledges on the Kickstarter site to help it make the jump from concept to production. The design consists of an uni-directional air valve and a small hollow tube on the outside of tire.
As you ride along the small outside tube is pushed flat allowing air to be squeezed into the tire, until it reaches its maximum pressure. Watch the video after the jump to see the concept in action.
A variety of tire designs have already been created tailored to different riding conditions, in the form of the City Cruiser for more casual riders with a 65psi and a City Pro High Performance Tire with a 100psi designed for the avid cyclist.
PumpTire was founded by Benjamin Krempel has been developed by a team of 15 individuals living across the US and Europe. Using Kickstarter it is now looking to raise $250k to be able to create around 5,000 tires and continue development. So if you feel the design is something you could use jump over and make a pledge to help it become reality.
