Brief Guide to Tire Inflators
Every year, thousands of families hit the open road and travel to another state. At the same time, millions of people get ready to start their commute to the workplace. An unexpected problem can ruin the day for these individuals, and it all comes down to a flat tire.
What Are They?
Tire inflators are designed to refill tires with air, and to accomplish this task, they use a pump. Most people are familiar with canned tire inflators, but the canned products don’t work like compressors. A canned inflator contains a special formula, and it’s used to seal a leaking tire. Tire inflators are different because they use a pump to compress air and push it into the tire.
These products work like the typical air station that you’d find at a gas station, but they don’t need quarters to work. Modern tire inflators are designed to plug into the 12-volt outlet in a vehicle, and the stream of electricity from the outlet powers a strong compressor, which compresses air and fills the tire.
Many of the newest inflators come with a digital gauge and make it easy to check the air pressure within the tire. The major advantage of owning an inflator is the peace of mind.
Drivers who own an inflator can’t avoid getting a flat tire, but when it happens, they’ll be prepared for it. The best tire inflators feature a compact design, and they can be stored away inside of a trunk or similar space.
How They Help?
Portable air compressors are very convenient because they’re effective and easy to use. A large, stationary compressor is perfect for the garage, but it’s not a good choice for traveling, and due to its large, bulky size, it won’t fit comfortably into most trunks.
Portable tire inflators are perfect for emergency tire repairs because they can deliver the compressed air needed to refill a flat tire.
Since these products can be plugged into a vehicle’s DC power, they don’t require a conventional electrical outlet, and with a specialized valve system, they connect easily to a flat tire. The problem that most people face is knowing when they’re going to get a flat tire, which is impossible.
Portable tire deflators allow drivers to take a defensive position against flat tires, and although there is no way to know when a tire will go flat, a high-quality deflator serves as the best way to be prepared.
Once the product is plugged into the vehicle’s electrical outlet, the compressor will start compressing air. After it has built up enough air pressure, it can be used to fill the flat tire.
How to Use Them?
Tire inflators are easy to use, and most modern designs connect to the 12-volt plug in a vehicle. Depending on the product, the pump might automatically shut off when it detects the proper air pressure within the tire, or it might need to be turned off manually.
A standard tire inflator features a compact size, and once it has been plugged into the vehicle’s DC power outlet, it will begin compressing air inside of its chamber.
Since most of these products are equipped with a convenient valve, they can be quickly connected to a flat tire, and as the pump compresses air, it pushes the air into the flat tire and raises the pressure. Some products come with a digital pressure gauge and additional accessories.
The major difference between products is the speed, and in most cases, a larger compressor will be able to compress and push air into a flat tire faster than a smaller compressor. When shopping for these products, this is something to think about.
It’s worth the extra money to purchase an inflator that comes with a built-in pressure gauge because most drivers don’t carry a gauge with them. It’s extremely important to know the exact air pressure within each tire because improperly inflated tires are unsafe, and they can have a significant impact on the vehicle’s driving stability.
What To Look For
If you want to have your tire inflator with you in the car to prevent being held up by a flat tire then you definitely need a 12V inflator as it will plug directly into your car’s charger outlet.
These also have the advantage that they’re usually lightweight and small, so they are easily packed into your trunk. And to top it all, they are inexpensive, so an easy addition to your mobile gear.
If you are wanting a tire inflator for general use rather than emergencies and want to inflate your tyres first, then you might want to look at a 120V inflator. These can be plugged into a mains socket at home and will inflate tyres faster than a 12V inflator.
Just bear in mind they’re not very portable as they will be heavier and not plug into your car’s outlet. They also have a limit to how much they can inflate – so generally can’t be used for an RV’s tires for example.
Maybe you want the best of both worlds, and would like a portable inflator for emergencies but also would like to be able to plug them in to the car or at home? There are some inflators available that are cordless and run off rechargeable batteries so these are ideal. They also have adaptors for 12V or 120V inputs so can be plugged in, in various outlets.
A key thing to look for is a pressure gauge, and ideally a pump that will turn itself off once it reaches a certain pressure so that you don’t run the danger of over-inflating. Some models even have preset settings for pressure so you won’t have to look up a specific value.
Different nozzles will help you maximise the use out of your inflator so that you can blow up air beds, save time on pumping up your bicycle tires, and inflate soccer balls.
Look to see how fast the inflators work, as you don’t want to be stuck by your car tires for 20 minutes while you wait. Ten minutes or under is generally a good time for a portable inflator to inflate a tyre.
If you’re bothered by a lot of noise, you might also want to look for one that is quiet – as they do vary quite a lot in how much noise they make.
Do you like bells and whistles on your inflator? You can find some that come with safety lights for if you find yourself with a flat tire at night. Some have built-in vacuums and jumper cables as part of it too, so if you need one of those anyway why not get it all in a package?
Who Can Benefit
Anyone who has a vehicle they drive in can benefit from one of these inflators. It’s a handy thing to have in the back of your car or motorcycle, so that you don’t have to call a friend to come and get you when you get a flat, and you don’t have to wait for roadside assistance.
Even if it’s a fast leak, often an inflator will pump up a tire enough to get to a garage or to your home if you’re close by.
Maintaining your tire pressure is key to road safety, and these tire inflators will help you stay safe if your pressure gets low either out and about or at home. It will also save you money as you won’t have to pay to use the air compressor at the local garage.
Inflators are also great for inflating tubing rings for a float down the river, or beach balls for a day at the beach. If you have an air bed they will come in handy to blow that up, and you can even use them for inflating footballs or basketballs.
What To Avoid?
Avoid getting too cheap of a tire inflator, as they can be hard to fold up after using them which makes them more difficult to store. It might be better to look for one that comes with a bag so it can be easily stored and stowed away in the back of your car.
Some units may overheat too, so you should be aware of that if you are inflating more than one tyre, or keeping it running for a longer time than usual.
You also want to be careful to either get one that shuts off once it gets to your required pressure, or always stay near it and keep an eye on the gauge so that the tire doesn’t over-inflate.
Also make sure you look at how long the cord is compared to where your charging outlet is on your vehicle. You don’t want to find that it doesn’t reach the tire that has a flat!
Will a tire inflator run the car out of battery?
It might run it out of battery if you don’t have the engine running, so to be safe it would be best to keep the engine on when you are inflating tires.
How do I know how much air to put in the tires?
On a car the recommended pressure should be either on a sticker inside the driver’s door frame, or inside the glove compartment, or in the manual. There is also a maximum PSI or KPA number printed on the tires but it is generally not recommended to fill them to that pressure.
Should the car be running when I use a tire inflator?
Yes, generally you want to have the engine running so that you don’t drain the battery from the car – otherwise you will have nicely inflated tires and a car that won’t start. It shouldn’t fry the inflator because the same 12V should come out of the charging outlet whether the engine is running or not.
What happens if the air pressure in tires is too low?
If the pressure in the tires is too low then more of the tires’ surface area will be in contact with the ground. This means that your tires will wear out sooner than they should and may also overheat, and lead to an accident.
The best tire inflator protects against unexpected flat tires, and it can prevent a fun vacation from getting ruined by a small nail or screw. These products are also useful for regular vehicle maintenance, and they’re useful for cars, trucks, SUVs, ATVs and bicycles.
