Never Pay For Air: How To Fill Up Your Car Tires For Free

Unless you’re in a pinch, paying for a self-service air compressor at the corner gas station isn’t necessary. There are plenty of free air hoses around, and in states like California and Florida, gas stations are even legally required to provide free air to customers.

For extra convenience, some drivers steer clear of the pumps altogether and buy a portable air compressor. Those eventually pay for themselves, plus add the safety of having air anywhere, anytime, while on the road.

Whether you’re looking for a service station with free air or the perfect portable compressor to keep in your vehicle, here’s what to know about options for refilling your tires for free.

How Much Does Filling Your Tires at a Gas Station Cost?

It depends. Some stations offer it for free, while others have self-service machines that typically cost between $1.50 and $5.00 for three to five minutes of air.

How To Find a Gas Station With Free Air

• FreeAirPump.com offers a crowdsourced map of locations providing free air.
• Wawa, Sheetz, Buckee’s, Racetrac and Costco stations all offer free air.
• Some local stations do, too. Look for an air hose on the side of the building. “If the gas station has a shop, most of the time they will air up a low tire for free,” says master-certified technician Chris Pyle.
• Local mechanics, oil change centers and car dealers may also provide the service, especially for regular customers.

“Some auto parts stores will also check your tire pressure and offer top-offs for free,” says Duane “Doc” Watson of Bosch Mobility Aftermarket. “It never hurts to call around and ask!”

How To Fill Your Tires for Free at Home

If you want to fill your tires without visiting a gas station, you can buy your own air compressor. Features to look for include portability, digital pressure measurement and automatic shutdown.

Portable 12-Volt Air Compressor

These compressors are powered via your car’s 12V power outlet (cigarette lighter), and generally cost between $25 and $60. They stow compactly in a vehicle and are easy to use: simply plug them in and attach them to your tire. “These provide excellent value because they pay for themselves during the first year, especially for those who own two vehicles or are heavy drivers,” says Alan Gelfand, owner of German Car Depot.

Pros recommendations: UUP Tire Inflator and EPAuto Portable Air Compressor. Pro-tip: Buy a model with ample cord length. “A common problem is the cord barely reaching the tires, or sometimes not at all,” says auto-industry expert Melanie Musson.

Rechargeable Cordless Inflators

Lithium-ion battery-powered tire inflators are extra convenient and compact, since there’s no cord to drag around. The downside is that they cost more, usually between $50 to $120, and the battery can wane over time if it’s never recharged. So if you’re not prone to maintaining that, “I recommend a plug-in one, since the battery one could be dead when you need it,” says Pyle.

Pro recommendations: Bosch EasyPump, Ampbank AT004 and Milwaukee M12 Inflator. For a combo battery plus 12V charger, try this Greenworks model.

Wall-Powered Air Compressor

Wall-powered (120V) air compressors aren’t practical for keeping in your car, since you need a house power outlet to run them. But, they are great for keeping in your workshop, where they can perform double duty, running power tools and pressure cleaning everything from car vents to floor rugs. They’ll also fill up your car tires faster than portable models. Costs range from $140 to $400, plus you’ll need a tire chuck and pressure gauge to fill your tires using one.

Pro recommendation: EcoMax.

Bicycle or Manual Foot Pump

You might already have a bike pump in the garage, and yes, in a pinch, you can use it to fill your car tires. Expect to spend $30 to $70. “A bike pump can work if your tire pressure is only slightly low, but may be a real pain if you’re trying to refill a significant amount of air pressure,” says Watson. “On the positive side, you could skip the gym after this method.”

Is It Worth It?

It depends on your budget and how hands-on you are with car maintenance, but in general, keeping a portable air compressor in your car is more about safety than saving money. Otherwise, “For most drivers, it’s perfectly reasonable to spend a few dollars at a gas station when needed,” says Watson.

But a compressor can save money in other ways, says Gelfand. “It promotes regular tire pressure checks, which enhance fuel efficiency, tire durability and safety,” he says. “Your fuel efficiency and tire condition can suffer when your tires operate at even five PSI below the recommended level.”
