Using gas station air on a bike tire
The 40 public air pumps mapped in Marylandare compressors, mostly at gas stations, convenience stores and car washes. Their air chuck is made for car tires, which use Schrader valves, the same valve found on most kids' bikes, cruisers and many mountain bikes. Road and gravel bikes usually have thinner Presta valves; for those, screw a small brass Presta-to-Schrader adapter onto the valve first. Our guide to Presta, Schrader and Dunlop valves shows which one you have.
A compressor fills a bike tire in a second or two, so press the chuck on for short bursts and check the pressure between them. If the pump has a preset gauge, set it to the pressure printed on your tire sidewall before you start. Coin-operated machines often run for a few minutes per payment, which is more than enough for two bike tires. Many stores switch the air on for free if you ask at the counter; the free air guide lists which chains usually do.
FAQ
Where can I get free air for bike tires in Maryland?
OpenStreetMap lists 40 public air pumps in Maryland; 38 are tagged as free and 7 as paid. Another 82 public bike repair stations are mapped, many with a built-in pump. Open the map to see the closest one.
Which Maryland city has the most public air pumps?

Can I use a gas station air pump for a bike tire?
Usually yes, if you add care: gas station compressors are built for car pressure and fill fast. Set the pressure on a bike gauge first, add air in short bursts, and use the right valve adapter for Presta valves.
