Self-Inflating Tires
Avoid Routine Gas Station Visits with the PumpTire

By: Omar Yusuf (Star) Aug 27, 11

Answering the desperate pleas of cyclists everywhere, the PumpTire hopes to reduce or altogether eliminate the need for pesky, routine reinflations of your bicycle tires.

As an everyday cyclist, it’s frustrating to know that my tires are constantly losing pressure even as I type this article, hundreds of feet away from my locked bike. Luckily, Benjamin Krempel and his venture-capital cohorts set out to solve this problem permanently. The PumpTire is comprised of three central components: an inner tube, a unidirectional valve and, of course, the tire itself. When the wheels begin spinning, pressure is exerted onto the inner tube, forcing atmospheric air into the valve where it is held. The result is a bike wheel that constantly reinflates as you ride!

Although the PumpTire is a fully functional product, the San Francisco startup behind it lacks the funds to roll the wheel out into the market. Their goal is to raise $250,000 before the PumpTire is released to the needy cyclists of the world.
