Paying two dollars for four minutes of air feels wrong, especially when the station across the street gives it away. The problem is knowing which one. FreeAirPumps answers that with one map: gas stations, tire shops and stores where you can fill your tires, and whether it costs anything.
Today the map lists 28,624 places in 50 states and Washington, D.C. You can use it without an account or an app, from any phone.
Where the locations come from
We combine open data sources and check them against each other:
- OpenStreetMap, the free world map edited by volunteers. It has most air pumps, gas stations and tire shops, often with hours and whether the air is free.
- The chains' own store lists, collected by the All The Places project. They fill in stores that are missing from OpenStreetMap and add addresses, hours and phone numbers.
- US Census boundaries to add the ZIP code and city where a listing lacks them.
- Your reports. Nobody knows a pump better than the driver who just used it.
How we decide if the air is free
We only call a pump free when we have a reason to. Each pin says how sure we are:
- Confirmed free: someone reported or mapped the air as free at this exact place.
- Free by state law (CA, CT): California and Connecticut require gas stations to give free air, so every public station there counts.
- Usually free (chain): the chain offers free air at most stores, but this store has not been checked yet.
- Tire shop · staff fill free: tire shops check and fill tires for free while they are open, without a self-serve machine.
- Unconfirmed: there is air, but we don't know the price yet.
Policies change and machines break, so a pin is a strong hint, not a promise. If you find something different on site, please report it. That is how “usually free” turns into “confirmed”.
Why it matters
Correct tire pressure saves fuel, makes tires last longer and shortens braking distances. Most drivers know that, but skip the check when air means hunting for quarters. When free air is one tap away, more people top up their tires, and the roads get a little safer.
