One way to encourage motorists to keep their tires fully inflated is to offer free air. So freeairpump.com has begun providing drivers with what it claims to be a comprehensive map of gas and service stations across the U.S. and Canada that offer free air.
The website is the brainchild of Brian Peterson, a senior at Illinois State University studying renewable energy and economics.
The user-generated website—which said it's for “anyone who is tired of digging for loose change or for bicyclists traveling light”—maps thousands of service stations that offer access to free air pumps for filling up tires.
Mr. Peterson spent months searching online and calling gas stations throughout the U.S. and Canada to build the site's initial database. The site is free of charge and its database continues to grow as users log onto the website and add new locations.
California and Connecticut are the only states that mandate a no-charge policy for service stations providing air pumps, according to the website, “which leaves travelers in 48 states in a frustrating position when they don't have change for the air pump.”
